####################################################################

This file contains a list of any changes you should be aware of when
upgrading from one version to the next, or even between multiple
versions. Be sure to heed the warnings contained herein as they will
save you many hours of grief.

7.7.19
--------------------------------------------------------------------
    * The search indexer was not properly indexing non-ASCII content
      entered via TinyMCE.  The behaviour has been corrected.  If your
      site has content in languages other than English, you should
      re-index the site.  This can be done with the search.pl utility
      script by running
        perl search.pl --configFile=www.mysite.com.conf --indexsite
      or, to index all of the sites on the server:
        perl search.pl --indexall

    * For searching content with ideograms, ft_min_word_len must be
      set to 2 in the Mysql config file.  WebGUI will safely pad the
      characters so that it does not need to be set to 1.  The WRE
      has ft_min_word_len set to 2 by default.

    * If upgrading from WebGUI 7.6, you must first upgrade to 7.6.35,
      then you can upgrade to WebGUI 7.7.19 and beyond.

7.7.18
--------------------------------------------------------------------
    * The search indexer was not properly indexing non-ASCII content.  The
      behaviour has been corrected.  If your site has content in languages
      other than English, you should re-index the site.  This can be done
      with the search.pl utility script by running
        perl search.pl --configFile=www.mysite.com.conf --indexsite
      or, to index all of the sites on the server:
        perl search.pl --indexall

7.7.17
--------------------------------------------------------------------
    * It was found that the combination of
        DBI: 1.52
        DBD-mysql: 3.002
      will cause an error during the 7.6.32 upgrade.  Later versions
      of these modules should work.

    * Spectre now works like many other programs and uses a PID
      file.  By default, it will use /var/run/spectre.pid, but you
      can change that in your spectre.conf file:

# The location of the file that keeps track of the master spectre
# processId.
"pidFile" : "/var/run/spectre.pid", ##Or some other location

      After installing this version, you should manually kill spectre and
      then modify the spectre.conf file to add the pidFile directive.

    * The Default Gallery Album View Thumbnails template has been reworked
      to get rid of intermittent rendering bugs with IE7.  The thumbnail
      pop-up is now completely CSS.  The thumbnails.js file is still available,
      but is now considered deprecated.

7.7.16
--------------------------------------------------------------------
    * There was some confusion about the state of 
      WebGUI::Shop::PayDriver::PayPal::PayPalStd.  While it was in fact
      dysfunctional, it was using the Paypal Website Standard API, while
      the new Paypal module was using Express Checkout.  Express checkout
      is only available in the US, UK, and Canada.  PayPalStd has
      been repaired, and the newly written Express Checkout module is
      available at WebGUI::Shop::PayDriver::PayPal::ExpressCheckout.

7.7.15
--------------------------------------------------------------------
    * WebGUI::Shop::PayDriver::PayPal::PayPalStd has been replaced by
      WebGUI::Shop::PayDriver::PayPal.  The old module by that name (a base
      class for PayPalStd) has been removed.  If you had the PayPalStd working,
      the new module very likely will not work (the old one did some very
      un-Shop things, which is why it was replaced).  Please test the new one
      with your setup.

    * 29 templates have been replaced with new ones. These are the templates
      for the Article, File, Folder, Image, Navigation, Layout, Poll, Search
      and Syndicated Content assets. 13 templates have been deleted (Article,
      Navigation and Layout templates). These were deleted because of deprecated
      code, redundancy and because we are want to reduce the number of
      templates. This will make the whole set of templates more comprehensible.

      Changes for all these templates:
      - extra divs, classes and IDs have been added;
      - consistent markup for recurring code, like titles, descriptions, attachments and pagination;
      - inline styles and deprecated code removed.

      Article
      - All Article templates:
          - Removed pagination. This will be re-added later, when the pagination macro bug has been fixed (bug #10619)
      - Default Article:
          - Added attachment loop (RFE #4152)
          - Removed code for image, since there now is a dedicated Article with Image template
      - Center Image:
          - Deleted: align="center" is deprecated
      - Left align image:
          - Changed name to Article with Image
          - Removed tables and added styles for img positioning
      - Linked Image with Caption
          - Removed tables and added styles for img positioning
      - Item:
          - Added attachment loop
      - Item w/ popup links:
          - Deleted: pop-up links are bad practice and this doesn't need to be a default
      - Article with files:
          - Deleted: attachment loop now added to Default Article
      - article.css added

      File
      - Default File:
          - The linktext is title instead of the filename (RFE #10173)
      - Flash File:
          - Template now uses swfobject code
          - Absolute width and height attributes are set in the html to replace the percentage value and inline style

      Folder
      - File Folder:
          - The linktext is title instead of the filename (like in the Default File template)
          - Tables have not been removed, since they are semantically correct here

      Image
      - Image:
          - Only added extra div with ID and class
      - Annotate Image:
          - No changes

      Changes for Navigation
      - crumbTrail:
          - No specific changes
      - verticalMenu:
          - Deleted: best practice is using "Bulleted List" for vertical navs
      - horizontalMenu:
          - Based on unordered list
          - Added styles
      - DropMenu:
          - Javascript cleaned up
          - Noscript alternative added
      - Tabs:
          - Based on unordered list
          - Added styles
      - Tree Navigation:
          - Javascript cleaned up
      - Hierarchical top nav:
          - Javascript cleaned up
      - Synopsis:
          - HTML based on definition list
      - Bulleted list:
          - Now always generates validating html (closing ul and li tags)
      - Indent Nav:
          - No specific changes
      - navigation.css added

      Layout
      - All table layouts:
          - Deleted: using tables for positioning is bad practice
      - All non table layouts:
          - Removed unnecessary divs ("layoutColumnPadding" and "content")
          - Styles for positioning added
      - One Over Two:
          - Newly added
          - Replaces News, but has one less content position
      - News, Three Over One, Left column:
          - Deleted: we want to reduce the number of templates and only kept the basic/most used page layouts
      - layout.css added

      Poll
      - Default Poll:
          - General cleanup, added extra classes and IDs
      - poll.css added

      Search
      - Default Search:
          - Results in a definitions list
          - Form post back to the current page instead of to the asset in wobject focus,
            this prevents possible "breaking" of the style

      Syndicated Content
      - Default Syndicated Content:
          - General cleanup, added extra tags, classes and IDs
      - Syndicated Articles:
          - General cleanup, added extra tags, classes and IDs
          - Removed inline style

7.7.13
--------------------------------------------------------------------
   * WebGUI has allowed metadata possible values to be processed differently
     by Posts than from other Assets.  This causes problems when metadata is
     shared between Posts and other Assets.  To rememdy this, all metadata
     possible values are being moved into the standard "pipe format", and
     the Post will no longer process data in the other format.

7.7.8
--------------------------------------------------------------------
   * A basic behavior of the Inbox has been changed.  If a message is
     sent to a Group of WebGUI users, and any member of the group reads
     the message, then that message is marked as read by all members.  This
     most often happens for commit reminders for version tags that require
     approval.  The old behavior often resulted in several users trying
     to approve version tags that had already been approved.

7.7.7
--------------------------------------------------------------------
   * WebGUI now requires Digest::SHA.
   
   * WebGUI now requires JavaScript::Minifier::XS 0.05
   
   * WebGUI now requires CSS::Minifier::XS 0.03


7.7.6
--------------------------------------------------------------------
   * You must upgrade to WebGUI 7.7.5 before going to this version. 

   * WebGUI now requires Business::Tax::VAT::Validation.

   * WebGUI now requires Crypt::SSLeay 0.57 or greater.

   * WebGUI now requires Scope::Guard 0.03 or greater.

7.7.5
--------------------------------------------------------------------
   * You must upgrade to WebGUI 7.7.4 before going to this version. 

   * Due to a long standing bug in the Profile system, if the type of a
     Profile Field was changed, the database column was not updated to match
     the requirements for the new type.  The most common place this problem
     would be noticed would be if a text field was changed to HTML field.

   * The Event url template variable was being used incorrectly.  This has
     been fixed, but requires new template variables for viewing a list
     of events, printing events and editing and deleting events.  Please
     check the online Help for the new template variables.

     Event templates using HTML::Template are automatically updated.  If your
     site uses a different parser for this template it will need to be manually
     upgraded.

   * WebGUI now requires HTML::Packer, JavaScript::Packer, and CSS::Packer 

7.7.4
--------------------------------------------------------------------
   * You must upgrade to WebGUI 7.7.3 before going to this version. 

   * WebGUI now requires XML::FeedPP version 0.40 or greater.

7.7.2
--------------------------------------------------------------------
   * WebGUI now requires Clone version 0.31 or greater.

   * You must upgrade to WebGUI 7.7.2 before going on to higher versions of WebGUI due
     to changes in the database table for the Cart.

   * The RSSCapable class and RSSFromParent asset have been removed.
     Any custom assets using those are recommended to switch to the new
     RssFeed AssetAspect.  If not used by custom assets, the tables
     used by them will be removed from the database.

     This will change the URLs for your RSS Feeds from "myAsset.rss" to
     "myAsset?func=viewRss".  You will need to update all Syndicated Content
     assets and other content aggregators that had the old URLs.  Alternately,
     you can use Redirect assets to forward the old URL to the new one.

7.7.1
--------------------------------------------------------------------
   * Keywords are now comma separated rather than space separated.  Quotes are
     no longer treated specially and will become part of keywords.  Keywords
     cannot contain commas.  Keyword searching is still case insensitive, but
     keyword will preserve the case of what is entered.


7.7.0
--------------------------------------------------------------------
   * WebGUI now requires Params::Validate version 0.81 or greater.

7.6.11
--------------------------------------------------------------------
   * If upgrading from WebGUI 7.5, you should upgrade to 7.5.40 first,
     then you can upgrade to WebGUI 7.6.11 and beyond.

7.6.10
--------------------------------------------------------------------
   * The Survey JSON fields (Survey.surveyJSON and Survey_response.responseJSON)
     will alter to longText from LongBlob's.

7.6.9
--------------------------------------------------------------------
   * The ukplayer example, slideshow.html in /extras/ukplayer, used
     to be loaded with a javascript called AC_RunActiveContent.js. 
     This file is removed due to licencing issues. If you use this 
     script in custom HTML, you should replace it with swfobject.js 
     as is demonstrated in the new example slideshow.html file. 

7.6.8
--------------------------------------------------------------------
   * Due to an error during the 7.6.6 development cycle, an Itransact template,
     for displaying the credentials screen, needs to be reimported.  Any changes
     that you have made to this module will be lost, so please make a back up
     of this template.

7.6.5
--------------------------------------------------------------------
   * The deprecated use of Graphics::Magick has been eliminated. WebGUI uses
     Image::Magick exclusively for all image processing functions once again.

   * The Head Block of Templates has been merged into the Extra Head
     Tags field.  Extra Head Tags are now added for all templates and
     assets included on a page, except for Style templates, which do
     not have Extra Head Tags.  Existing Extra Head Tags for Style
     templates will be lost.  If your current Style template uses
     the Head Block please put any content from there directly into your
     style template inside the <head></head> tags.

   * Web Services Client is no longer part of the official distribution of
     WebGUI, but is still available to be maintained by third-parties. However,
     if you don't want to use Web Services Client any longer, make sure you
     delete all Web Services Clients from your site prior to the upgrade *and*
     purge them from your trash. Then the upgrade will automatically uninstall
     the Web Services Client from your site.


7.6.4
--------------------------------------------------------------------
   * The user facing portions of WebGUI's profile, inbox, friends, and "invite
     a friend" systems have been completely updated.  No data will be lost
     but all templates including custom templates that are related to these
     systems will be deleted on upgrade.  Please make sure you export your
     custom templates prior to upgrading as you will need to modify them for
     the new system.

   * The Auth display account template no longer has the account.options loop
     available.  This loop has been replaced entirely by macros to provide more
     flexibility.  Any custom templates will need to be updated accordingly.

   * The Survey system has been completely updated.  Please make sure you
     create full backups of your survey results and export them as needed.
     Results will not be imported into the new Survey system.  Your old surveys
     will be imported into the new survey system.


7.6.3
--------------------------------------------------------------------
 * WebGUI now requires XML::FeedPP version 0.36 or greater.

 * The Syndicated Content asset has been heavily modified. Your templates
    and settings should automatically migrate, but in less than 1% of cases
    there will be problems that the migration cannot handle. Check your
    Syndicated Content assets after upgrade to ensure they are still
    working as expected.

7.6.1
--------------------------------------------------------------------
 * WebGUI now requires Class::C3 version 0.19 or greater.


7.6.0
--------------------------------------------------------------------
 * WebGUI now requires Module::Find version 0.06 or greater.

 * You must be fully upgraded to 7.5.24 before upgrading to 7.6.0

 * You can no longer template the AdminBar macro. Any custom template
   id that you pass it will be ignored, and the original template will
   be removed from your site.


7.5.21
--------------------------------------------------------------------
 * Previous versions of WebGUI used the wrong day of the week for
   scheduled workflows.  This resulted in them being run a day later
   than they should have.  If you relied on the old behavior, you
   will need to update your workflow schedules.


7.5.19
--------------------------------------------------------------------
 * WebGUI now requires Text::CSV_XS version 0.52.  If you have been
   using an earlier version you will need to upgrade this perl
   module before you upgrade.

 * If a user profile field allowed multiple selects, and it also had
   more than one default value, the User method profileField would
   return the first.  It will now return all default values as a string,
   joined by commas.

7.5.17
--------------------------------------------------------------------
 * If users are allowed to self register and emails are not required, this
   might cause downstream bugs in other assets that require email addresses.

7.5.16
--------------------------------------------------------------------
 * You need the following Perl Modules installed before you upgrade:
    File::Path


7.5.13
--------------------------------------------------------------------
 * RSSFromParent now uses the parent asset's canView method to 
   determine if the user is allowed to see the RSS feed.
   The upshot of this is that a user must be able to view the 
   Collaboration System in order to view its RSS feed.
   Previously, RSSFromParent did no view restrictions, allowing 
   anyone with the right URL to see an RSS feed, even if they do not
   have permission to view the Collaboration System it came from.

 * The 7.5.11 upgrade contained a bug that didn't import existing
   Data Form entries properly.  The script has been corrected, so if
   you didn't already upgrade to 7.5.11, there is nothing to worry
   about.  If you already upgraded, the information can be restored
   from a backup. See
   http://www.webgui.org/bugs/tracker/data-form-listing-existing-entries-wrong-missing-data
   for information on how to retrieve this information without having
   to revert entirely to a past backup.


7.5.11
--------------------------------------------------------------------
 * You need the following new Perl Modules installed before you upgrade:
    Archive::Any
    Exception::Class
    Path::Class
    Image::ExifTool
    List::MoreUtils

 * SQL Form is no longer part of the official distribution of WebGUI,
   but is still being actively maintained by third-parties. However, if you
   don't want to use SQL Form any longer, make sure you delete all SQL Forms
   from your site prior to the upgrade *and* purge them from your trash. Then
   the upgrade will automatically uninstall the SQL Form from your site.

 * WebGUI versions since 7.3.0 (when the new Calendar was added) 
   have allowed users to post Events to Calendars, but the owner of
   the Event has been saved as Admin (user ID 3). Also, anyone who
   was allowed to add an Event was allowed to edit any Event in the
   Calendar.
   The permissions have now been fixed, but it is not possible to
   fix the owner of Events posted by individual users. Users are
   not allowed to edit the owner of an Event from the web interface
   as a security measure.
   The new permissions are:
        * Users who post an Event are allowed to edit and delete the
          Events they post
        * Users who can edit the Calendar are allowed to add, edit,
          and delete all Events

 * The commerce system was completely rewritten. As such you will need
   to tweak some settings to get commerce back up and running.

 * Shipping configurations are going to be lost when you upgrade. You'll
   need to set up a shipping option if you're using the commerce system.

 * Products in the old Commerce system have been converted to new Asset-based
   Products in a new folder called Products.  Instead of using the ^Product()
   macro to display a Product on a page, either place the Product directly
   onto a page (like any other asset) or use the AssetProxy macro.  In all
   Wobjects, Templates and Snippets, the Product macro has been replaced
   with the AssetProxy macro.

 * The Product template variables now use the new WebGUI standard of not
   using dots in their names.  For example, brochure.icon is now brochure_icon

 * All Product Templates that shipped with earlier versions of WebGUI have
   been deleted, except for the Default Product Macro.  During the upgrade,
   all products have been updated to use the Default Product Macro.  If you want
   to keep these, you will need to make a copy of them before the upgrade.

 * All Commerce Templates that shipped with earlier versions of WebGUI have
   been deleted.  If you want to keep these, you will need to make a copy of
   them before the upgrade.

 * Subscriptions have been converted to assets. These assets will be placed in 
   the import node in the folder 'Migrated Subscriptions'. 
   
 * It used to be possible to link subscription codes to multiple subscriptions. 
   This is no longer the case. Subscription code that are not yet expired or used
   and link to multiple subscriptions will be migrated in the following manner:
     1) The subscription codes will remain valid for one of the subscriptions they
        linked to.
     2) For the other subscriptions connected to these codes new subscription codes 
        will be generated. The upgrade script print all the new codes in the case.
        The new codes will also be logged in the webgui log file.

 * With the new shop system the Payment plugins have been changed too. The default
   WebGUI Payment Plugins are automatically migrated for you, but custom plugins 
   will have to be adapted to use the new WebGUI::Shop API.

 * If you are using the ITransact payment plugin you'll have to change the postback
   url. The new value is printed by the upgrade script and can also be found in
   the edit screen of the ITransact plugin.

 * The Commit With Approval and Commit Without Approval workflows have been
   rebuilt.  If you have changed these default workflows and wish to retain your
   changes, be sure to back them up before you install 7.5.11

7.5.9
--------------------------------------------------------------------
 * WebGUI 7.5.6 uses a Unicode database connection, but this can cause problems
   with old data stored in an erroneous format.  The 7.5.6 upgrade has been
   adjusted to compensate for this.  If you are upgrading from prior to 7.5.6,
   the data should be repaired automatically.  However, if you had already upgraded
   past 7.5.6, there is no automated way to resolve the differences in the data.
   For information on how to resolve this if you have already upgraded, see
        http://www.webgui.org/bugs/tracker/charset-db-connection


7.5.4
--------------------------------------------------------------------
 * YUI has been upgraded to 2.5.0.  The resizable textarea implementation in
   WebGUI has been rewritten using YUI instead of the Ext library.  This has
   removed Ext as a depenancy, and it has been removed.


7.5.1
--------------------------------------------------------------------
 * The resizable textarea implementation in WebGUI has been reimplemented to use
   the code present in YUI 2.5.0. As such, WebGUI's YUI implementation has been
   updated to version 2.5.0, and the no-longer-needed extjs library has been
   removed.


7.5.1
--------------------------------------------------------------------
 * There was a corrupt template in a package for the 7.5.0 upgrade.
   If you already upgraded to 7.5.0, please import the package 
   located at: 
   WebGUI/docs/upgrades/packages-7.5.0/root_import_timetracking_user.wgpkg

 * WebGUI requires newer versions of some existing modules. Be sure to
   install them BEFORE upgrading. They are:

        JSON 2.04
        Config::JSON 1.1.2


7.5.0
--------------------------------------------------------------------
 * You must upgrade to 7.4.40 before you upgrade to 7.5

 * Event related links are now displayed using a template loop 
   rather than a template variable. See the default templates for 
   details.
   Your custom Event Edit and Event View templates may need fixing.

 * If you want to use the beta, you must first upgrade to 7.4.21 then
   upgrade to the beta. If you upgrade past 7.4.21 then you cannot
   use the beta.


7.4.12
--------------------------------------------------------------------
 * Any customizations made to the Matrix default Search, Compare or
    Detailed listing templates will be lost.  Please back up your
    custom templates before running the upgrade.


7.4.11
--------------------------------------------------------------------
 * The 7.4.8 upgrade script had an error for sites using Dashboards.
    This would prevent the script from completing successfully.  The
    script has been fixed for future releases.


7.4.3
--------------------------------------------------------------------

 * You must upgrade to Config::JSON 1.1.0 or higher prior to upgrading.
    Due to a bug in CPAN you should type "force install Config::JSON" in
    order to upgrade to this version.
 
 * For Poll Wobjects, we're using a new way to store the graph 
    configuration. If you were having problems with your Poll graphs, 
    you will need to re-create the graph's configuration. It may not
    be possible to read your graph configuration, so if you have 
    problems with the Poll graphs you will need to re-create the graph's
    configuration. After you create a new configuration, everything will
    work fine.


7.4.0
--------------------------------------------------------------------

 * You must upgrade to the latest 7.3.x release before upgrading to
    7.4.0 or you will encounter fatal errors during the upgrade
    process.

 * The userProfileData table has been completely re-done. Now, each
   user profile field has its own column in the userProfileData table.

   Any applications that you may have that makes raw SQL queries against
   the userProfileData table will need to be updated to reflect these
   changes.

 * DatabaseLinks no longer automatically set LongReadLen and LongTruncOk
   for Oracle or ODBC databases.  These parameters, and others, can now
   be set in the DatabaseLink.  The old settings used were
     LongReadLen: 512*1024
     LongTruncOK: 1

 * WebGUI now requires the following additional perl modules to operate,
   and you should install them prior to upgrading:

    Config::JSON
    Text::CSV_XS
    Class::InsideOut
    HTML::TagCloud

 * WebGUI now uses Graphics::Magick instead of Image::Magick for
   image processing functions. However, for the next few versions you
   will still be able to use Image::Magick if you already have it
   installed, to make the transition easier. Graphics::Magick is a
   fork of Image::Magick, but it's focus is stability and compatibility
   over adding new features. Another note will be added to this file
   when support for Image::Magick is officially removed. That will
   most likely happen in WebGUI 7.6.0. Note that WRE 0.8.0 includes
   Graphics::Magick, so if you upgrade to WRE 0.8.0 then you'll
   automatically be ready for the future.

 * Any customizations made to the Inbox or Inbox/Message templates 
   will be lost. Please back up your custom templates before running
   the upgrade
   
 * The Transaction Error template in commerce has been merged with the Checkout 
   template.  All Transaction Error templates are purged from the system on upgrade.
   Make sure you back up your custom templates and apply them to the Checkout template.
   None of the template variables have changed.


7.3.19
--------------------------------------------------------------------

 * There was a bug fixed in this release relating to the Image asset.
   The bug was that if you edited an Image, then the original image file
   in the asset was replaced with its thumbnail.  There is no easy way to
   automatically fix this the results of this bug.  To recover affected
   Image Assets, then just upload a copy of the original image file.  You
   do not need to Trash/Delete the Image Asset.


7.3.16
--------------------------------------------------------------------

 * There was an inadvertent override of the Asset method isLocked inside
   of WebGUI::Asset::Post::Thread.pm.  Normally, isLocked will return true
   if the Asset is being edited by another user.  However, the isLocked inside
   of Thread.pm returned true if the Thread was locked to prevent more
   replies from being added to the it.

   In 7.3.16, the thread lock method inside Thread.pm was renamed
   isThreadLocked.  No template variables, field names or database
   columns were changed.

 * The create.sql script for 7.3.15 was released with 7.3.16. While
   upgrading to 7.3.17 you'll notice it also processing the 7.3.15-
   7.3.16 upgrade. This is to be expected.

7.3.15
--------------------------------------------------------------------

 * The Event Management System now uses an extra table to store
   information about events in the user's cart. This fixes a bug
   where a user that logs out after adding events to their cart but
   before they complete their transaction will be charged for their
   events but not registered for them.

   Existing sessions affected by this bug are not fixed, so there may still 
   be errors. This SQL query will get the session IDs of the
   sessions affected by this bug:

    select distinct(sessionId) 
        from shoppingCart 
        where itemId IN (SELECT productId from EventManagementSystem_products) 
            AND sessionId IN (SELECT distinct(sessionId) FROM userSessionScratch WHERE name LIKE "purchaseId%");
   
   You may want to expire these sessions from the Admin Console > 
   Active Sessions screen.

7.3.12
--------------------------------------------------------------------

 * The sbin/thumbnailer.pl script was almost completely rewritten.
   It now accepts a script to only thumbnail things that do not
   already have thumbnails, to help compensate for problems with
   the RTE Collateral Image manager upload/thumbnail bug.
   Run the script with no arguments to get a summary of the new
   usage.

7.3.11
--------------------------------------------------------------------

 * The weather data asset stopped working because our old weather
   provider went away. We've remade the weather asset using a data
   feed from weather.com. The feed is free, but you'll have to
   register to use it on your site. The up side is that the weather
   asset now supports international cities.

   You must now also have Weather::Com::Finder 0.5.1 installed. Do
   this before you upgrade.

7.3.10
--------------------------------------------------------------------
 * This version fixes a bug in the 7.2.3-7.3.0 upgrade where the
   incorrect revision of an Event would be migrated.
   
   If you have already upgraded, either restore from a backup or
   go over your Calendars and ensure that your Event's informations
   are accurate.
   
   If you have not yet upgraded, you do not need to do anything.

7.3.9
--------------------------------------------------------------------
 * This upgrade may appear to freeze when it gets to the "Adding
   thread rating column" step, especially if your site has a large
   number of collaboration systems and posts.  Let it run, it's
   working.  We have to recalculate the rating for every single post
   and it can take upwards of an hour on large sites.

 * If you're using the Events Management System and have a custom
   checkout template, you will need to use the following template
   variables to implement the fix: isError, errorLoop, error.
   Documentation on their use is in the online help and you can also
   look at the default template for an example use.

 * The c_companyName macro now uses HTML encodings for comma and
   single quote to make it safe to embed inside other macros.

7.3.8
--------------------------------------------------------------------
 * For those who upgraded to 7.3.7, any EventsCalendars (with their 
   attached events) in the trash or on the clipboard during the 
   7.2.3 - 7.3.0 upgrade were NOT migrated. This version will delete 
   those from the database, since it is not possible to recover them 
   based on their current state.
   
   Those who are upgrading from 7.2.3 - 7.3.8 will not lose any 
   data.

   NOTE: Any Events Calendars in the trash will be purged and no 
   longer recoverable.
   

7.3.7
--------------------------------------------------------------------
 * For those who performed a multiple site upgrade from 7.2.3 to 
   7.3.1 or higher and began having problems with navigation and 
   calendar wobjects, you can fix those problems by restoring your 
   7.2.3 database, restoring the 7.2.3 WebGUI source, re-applying 
   the 7.3.7 WebGUI code, and running the upgrade again.
   If you are not affected by these problems, you do not need to 
   restore.

7.3.5
--------------------------------------------------------------------
 * Template variables used in templates that use XML, or that are used
   inside of Javascript need to be escaped to make quotes and other
   characters safe.  This can be done by appending ESCAPE="HTML" or
   ESCAPE="JS" to the tmpl_var tag.  Examples were added to the
   Template Language help page.

 * A javascript confirmation was added to the default Edit Wiki Page
   template.  It will need to be manually added to custom templates.

7.3.2
--------------------------------------------------------------------
 * The testCodebase.pl script will now automatically set the CODE_COP
   script unless you give it the --noLongTests switch.

7.3.0
--------------------------------------------------------------------
 * The i18n/label.t and help/setHelp.t test now require that you set
   an environment variable, CODE_COP to run them.  This should make
   running the entire test suite prior to SVN commits easier to do
   since it won't take so long.

 * Password recovery has been redone, and is now based on profile fields
   rather than email access.  Since there's no real way to migrate the
   one to the other, this upgrade _disables password recovery_.  The template
   variables for password recovery are also different, so if
   you have a custom template, you will have to update it.

   To enable password recovery, you must first pick a set of profile fields
   to use such that any user who knows that set of fields can reset their
   password based on those.  Edit each of those profile fields to turn the
   "Required for password recovery?" flag on; then you will be able to
   enable password recovery.  It is highly advisable to pick several fields,
   as one field only is very easy to break.

   There is a new Calendar wobject which replaces the current EventsCalendar
   wobject.  The upgrade will migrate all of your events but it will *not*
   migrate any of your custom templates.  All custom event calendar templates
   will be *_D E L E T E D_* so make sure you have a backup if you need them.
   Also, the Event List view of the calendar works a little different
   than it used to.

   The upgrade script takes an unusually long time to migrate EventCalendar
   wobjects to the new Calendar wobjects.  We're looking into the cause but
   don't kill your upgrade thinking its hung up, we promise it will finish.

7.2.0
--------------------------------------------------------------------
 * NOTE: if you tried to upgrade to 7.2.0 and it failed during the
   addition of RSS From Parent capability, there have been bugs fixed
   in that section of the relevant upgrade script in 7.2.1.

 * Server side spellchecking has been added to this release. You must 
   install Text::Aspell, and any dictionary you like. If you want to 
   use spellchecking you have to setup the dictionaries you want your 
   users to use in the config file. Also you'll have to check the 
   spellchecker checkbox in the RichEdit asset you're using.

 * The sales tax in the commerce system requires the Locale::US perl
   module.  You will need to install it.

 * To combat a phishing exploit, all image form controls used in the
   user profiling system now default to a state that only allows 
   image files to be uploaded through them. If you have a user profile
   field that needs to accept images and files you will need to edit
   that field and set the "Force Image Only" property to No.
	
7.1.3
--------------------------------------------------------------------
 * The column that stores the graph configuration in the Poll table 
   has the wrong type. In MySQL 5 this results in corruption of this 
   hash. The upgrade script will fix the column type, but not the 
   corrupted graph configs. Polls with an erroneous configuration
   will display the old text based graphs. To fix the Polls, just edit
   them, set the correct graphing options again and finally save.
   
7.0.8
--------------------------------------------------------------------
 * 7.0.7 was released with a critical bug that broke the search engine
   for many sites, but not all. This bug has been corrected and tests
   have been written to help ensure it doesn't happen again. However,
   as a result you must rerun the search indexer program (sbin/search.pl)
   on all your sites.


7.0.4
--------------------------------------------------------------------

 * Version 7.0.3 shipped with a 7.0.2 create.sql script. This doesn't
   really hurt anything, it just means that if you installed 7.0.3
   as your starting point, you'll see an extra upgrade go through
   when you upgrade to 7.0.4.



7.0.3
--------------------------------------------------------------------

 * Numbers generated by the Splat_random macro were not evenly
   distributed.  It returned numbers between 0 and 'max' (inclusive)
   with this two numbers occurring about half as much as other numbers.
   This is now fixed, so it will return numbers between 0 and 'max-1'
   (inclusive), with an equal probability of any of these numbers.
   If you're using this macro, you might need to increment the max
   parameter.

 * We've made a number of improvements and bug fixes to the search
   indexing system in this release. You may want to use the search.pl
   utility in sbin to reindex your site to get better search results.


7.0.2
--------------------------------------------------------------------

 * We've cut the memory leak in half. It turns out we had a bad perl
   module that was causing a big part of the memory leak. As such,
   you now need to install POE::Component::Client::HTTP.


7.0.0
--------------------------------------------------------------------

 * There is a memory leak in Spectre. We're working on a solution to
   this problem, but in the mean time you will need to restart spectre
   every so often to clear out the memory. We recommend setting up a
   cron job to restart it once per day.


6.99.5
--------------------------------------------------------------------

 * In transferring LDAP from the users to group module, it was discovered
   the ldap link must also be saved with the group.  The upgrade attempts 
   to determine the proper LDAP Link to use, however it is not guaranteed
   to be accurate.  If you use LDAP groups in WebGUI, be sure and check 
   each one to make sure they are assigned to the appropriate LDAP Link.


6.99.4
--------------------------------------------------------------------

 * A bug was just discovered in the WebGUI::Auth API in that it was
	missing the editUserSettingsFormSave() method. If you have
	built your own auth module, then you need to add this method
	or your auth settings will not save. See WebGUI::Auth::WebGUI
	for an example of how to do this. If you are not using custom
	auth, then don't worry about this.


6.99.0
--------------------------------------------------------------------

 * The 6.99 series is the last round of changes before 7.0.0 is
	released. It will serve as the beta, gamma, and release
	candidates for 7.0.0.

 * The group SQL query mechanism has been changed to be more efficient,
	more practical, and more consistent with the rest of WebGUI. As
	such, your old query will no longer work. You used to do something
	like "select 1 from table where foo='bar'", but now you need to
	"select userId from table where foo='bar'".

 * The "messageLog" table will be deleted during the upgrade process,
	and all of the messages in it. This is because the messages
	contained in there are no longer useful because they won't
	work with the new workflow system. If you need the data in
	that table, you should save it before performing the upgrade.

 * The session system has been replaced by a new object-oriented one,
	which has caused massive API changes. Please consult
	migration.txt to bring your custom code up to date with the
	new API.

 * You need to upgrade to the latest 6.8 release before you can
	upgrade to 6.99.

 * If you wish to use one of the new optional template engines
	you'll need to install the perl modules for them:

	Template
	HTML::Template::Expr

 * In order to make the upgrades run quickly, the upgrade process
	will not automatically index your sites for the new search
	engine. You need to do this manually after the upgrades
	have completed by running the search.pl script in the
	sbin folder.

 * The following perl modules are now required:

	MIME::Tools
	POE
	POE::Component::IKC::Server
	POE::Component::Client::UserAgent
	Net::Subnets
	DateTime::Format::Mail
	Net::POP3
	List::Util
	Color::Calc

 * The upgrade script is going to convert your WebGUI config files
	from the current PlainConfig format to the new JSON format.
	Don't be alarmed by this, it's a normal part of the upgrade
	procedure.

 * You no longer need the cron job for runHourly.pl. Instead, you
	must start sbin/spectre.pl when your server starts up.
	Spectre is WebGUI's offline execution engine. It triggers
	scheduled events and executes workflow tasks. Be sure to
	edit each of your WebGUI config files to set the
	spectreSubnet setting to match your IP address or IP range.

	Running spectre requires a spectre.conf file.  Like the
	log.conf file, the name is fixed.  Make a copy of the sample
	spectre.conf, etc/spectre.conf.original, and place it in the
	etc directory.	Then make any final edits or configurations
	and start /sbin/spectre.pl.

	You must have a spectre.conf file before you run the upgrade
	to 6.99.0.

 * If you wish to run the full test suite, you'll need to install
	these optional modules:

	Test::Deep
	Test::MockObject

 * The content in the import node has had inappropriate privileges
	since it was created. We're resetting the privileges to be
	viewable by everyone and editable by the turn admin on
	group. If this is not what you want for your site, or for
	segments of the content in your import node, you'll need
	to change it after the upgrade.

 * Because collaboration system posts are now integrated with
	the workflow engine, the approve/deny links are no longer
	needed or used in your templates. In addition if you wish
	to use an approval process on any of your collaboration 
	systems, you'll need to re-enable it after this upgrade.


6.8.4
--------------------------------------------------------------------
 * The If macro has been removed because it's far too dangerous and
   	error prone. If you use the If macro you may continue to use
        it at your own risk, maintenance, and support cost, but it
        is no longer supported by Plain Black.




6.8.1
--------------------------------------------------------------------
 * Before upgrading you must install the following new Perl modules:
	Data::Structure::Util

 * Fixed a major versioning system bug in this release where when purging 
	the last revision of an asset, if it had children, the children were 
	not purged with it. This may have caused problems in some people's 
	databases if they used any 6.7.x version or 6.8.0. If it has all you 
	need to do to fix it is upgrade to this release and then run 
	sbin/rebuildLineage.pl


6.8.0
--------------------------------------------------------------------

NOTE: If you're upgrading from MySQL 4 to 5 you MUST do a mysqldump on your
databases from 4 and then after upgrading to 5, reimport them. If you do not
do this your databases will become corrupted.


 * Before upgrading you must install the following new Perl modules:
	DateTime
	DateTime::Format::Strptime
	DateTime::Cron::Simple
	JSON
	Finance::Quote
	Archive::Zip

   And optionally, these:

	Test::More
        Pod::Coverage

 * If you have previously installed the community contributed version
	of the In/Out Board (IOB) then you will need to completely
	uninstall it before you can proceed with this upgrade.

 * The core API has changed. Check docs/migration.txt for details.

 * WebGUI now requires Apache2 with mod_perl2 so CGI, FastCGI, PerlEx,
	although never officially supported, are no longer possible.
	Making this change gave us more than 70% performance improvement
	and opens up even more possibilities for performance and other
	optimizations.

	You'll need to make the following changes in Apache to upgrade
	to this release:

	Install libapreq2. You can either download and compile this
	from the mod_perl web site, CPAN as Apache2::Request, or by
	getting the version of the WRE 0.6.0 or higher.

	Edit your httpd.conf or httpd.modperl.conf and add the following
	directives to your global server config:

  	LoadModule apreq_module modules/mod_apreq2.so
 	PerlSetVar WebguiRoot /data/WebGUI

	You may also remove this block if you have it:

	<Files ~ "\.(pl)$">
    		SetHandler perl-script
    		PerlHandler ModPerl::Registry::handler
    		PerlOptions +ParseHeaders
	</Files>

	You also no longer need the ExecCGI directive.

	Edit each of your virtual hosts and add the following directives,
	changing them to suit your needs:

	SetHandler perl-script
        PerlInitHandler WebGUI
        PerlSetVar WebguiConfig www.example.com.conf

	If you were using mod rewrite you'll need to adjust your rules
	because they no longer need to remove the gateway (index.pl)
	from the URL.

	If you were using the uploadsAccessHandler.perl you no longer
	need that as it is built in to the WebGUI handler.

	For more information consult the WebGUI Done Right documentation.

 * WebGUI now requires MySQL 5.0 to operate. This is due to the huge
	number of new features afforded us in the MySQL 5.0 database,
	which will increase performance, and add to our functionality
	for the future.

 * WebGUI now requires Perl 5.8 to operate.

 * The Macro API has been changed. If you have any third-party macros
	installed make sure to update them prior to upgrading. See
	docs/migration.txt for details.

 * You may now optionally create sbin/preload.exclude with a carriage
	return seperated list of modules you don't want to be preloaded.
	This file requires each line to contain exactly one full module
	name such as "WebGUI::Asset::Wobject::WSClient" (without the
	quotes) per line. No spaces or additional formatting can be
	present. You may, for example, just copy sbin/preload.exclude.example
	to sbin/preload.exclude and save yourself about 5MB of memory
	because that will eliminate some of the least commonly used
	components. 

	If you mistakenly exclude modules that WebGUI actually needs
	to run, it will load them at run time, and just use more RAM,
	so you don't need to worry about breaking WebGUI. However, this
	doesn't mean you should just exclude everything because doing
	runtime loading will likely use 5-10 times more RAM than just
	preloading them to begin with.


6.7.0
--------------------------------------------------------------------
 * In order to upgrade to 6.7 you must first upgrade to at least 6.6.1.

 * The asset API has changed slightly due to versioning, so if you
	have any custom assets, check out migration.txt to make
	sure they will comply.


 * The templates for Survey assets has changed a little.  After
        upgrading you will notice that your custom view templates
	will not display your questions for editing in Admin mode.
	You will need to put your questions loop inside of a section
	loop.  See the default view template for an example.

 * If you have any SQL reports going against the asset table, note that
	it has been split into two tables "asset" and "assetData" and
	your SQL reports will need to change.

 * The indexed search asset has been disabled until 6.8 where it will
 	be entirely rewritten from the ground up.


6.6.4
--------------------------------------------------------------------
 * Please ensure you're running HTML::Template version 2.7, which
        supports javascript escaping and is needed to ensure js
        menus work everywhere. To see what version you're running,
        type:
        perl -MHTML::Template -e 'print $HTML::Template::VERSION."\n"'
        at a command prompt, or alternatively use the
        sbin/testEnvironment.pl script included with WebGUI. If
  	you've had your WebGUI site running on versions prior to 6.4
	then you should delete your lib/HTML folder as it contains
	an outdated version of HTML::Template.


6.6.3
--------------------------------------------------------------------
 * If you created your site using the create.sql script from 6.6.2
        you will need to recreate it from the new create.sql script
        from 6.6.3. The 6.6.2 version has some unrecoverable
        problems in it. If you just upgraded to 6.6.2, you need not
        worry, the upgrade is unaffected by this problem.

 * If you're randomly getting logged out before upgrading to this
        release, clear your browser cache and cookies after upgrading
        to this release and the problem will go away.


6.6.0
--------------------------------------------------------------------
 * Perl modules that used to be shipped with WebGUI are now required
	to be installed on your system manually. You can optionally
	just use the WebGUI runtime environment to save yourself
	the hassle of downloading all of them. You can also install
	them using testEnvironment.pl The new modules you'll need 
	to install are:

	Log::Log4perl
	Net::LDAP
	Date::Manip
	DBIx::FullTextSearch
	HTML::Highlight
	HTML::TagFilter
	HTML::Template
	Parse::PlainConfig	
	Tie::IxHash
	Tie::CPHash
	XML::RSSLite
	XML::Simple

 * After upgrading you'll need to create a log.conf file in your etc
	folder for the new logger. For most situations you can just copy 
	log.conf.original to log.conf and you'll be fine. If you want
	to set up custom logging rules, see this web page:
	http://log4perl.sourceforge.net/releases/Log-Log4perl/docs/html/Log/Log4perl/Config.html

* The Payment plugins should provide two new methods: shippingCost and 
	shippingDescription. Plugins that do not have these methods
	will fatal error when checking out.

* The Commerce/ConfirmCheckout template has a lot of new variables to
	use, but also some (existing ones) have been renamed. Please refer
	to the corresponding help file.


6.5.6
--------------------------------------------------------------------
 * The uploadsAccessHandler.perl script has specific issues with
   various versions of mod_perl and Perl CGI due to the many recent
   changes in mod_perl and Perl CGI. For this reason it may not work
   on your platform. We're working to make a script that will work
   everywhere. Until then, using the latest versions of mod_perl and
   Perl CGI should produce working results.


6.5.0
--------------------------------------------------------------------
 * The International Macro must be enabled in all WebGUI configuration
   files for the Help to work correctly.

6.4.0
--------------------------------------------------------------------
 * Image Magick is no longer optional.


6.3.0
--------------------------------------------------------------------
 * After upgrading your site you'll have to reset the privileges on
        your uploads folder to make sure that the web server has
        the privileges it needs to write due to a large number of
        changes on the filesystem.

 * In order to upgrade to 6.3.0 or beyond you need to have already
	already upgraded to 6.2.0 or above. The upgrades will fail if
	you try to jump from any 6.1 (or prior) version directly to
	6.3.

 * Your upgrade process will be a little different from here on out.
	Use the following steps to do the upgrade:

	a) Back up everything.

	b) Extract the 6.3 archive over your existing install.

	c) Restart apache (don't shut down as normal, just restart).

	d) Run upgrade.pl in the sbin folder.

	e) Test.

	The reason for this is that WebGUI has an innovative new way
	of releasing sites for public view as soon as they become
	available during the upgrade, even while the other sites are
	still being upgraded. Each site will have a maintenance 
	message displayed until its upgrade is complete.

 * The EmptyTrash scheduler plugin has been removed since there's no
	need for it with the more useful DeleteExpiredTrash module in
	place.

 * This upgrade process will run for a very long time and output a
	lot of debug information which will be useful if something
	goes wrong. You may wish to pipe the debug info to a log
	file like this:
	
	perl upgrade.pl --yourcommandlineoptions > /tmp/upgrade.log

 * If you're using languages other than English, you'll need to get
	new versions of those language files before upgrading. The
	language file format has a new requirement. Also, the
	language files are now all converted to UTF-8.

 * If you were using any non-English language files on your site,
	you may now have to convert your site content to UTF-8
	format. Check with your language file provider for details.

 * If you're upgrading from a release earlier than 5.5.0 then you'll
	need to download and upgrade to 5.5.x before you can upgrade
	to 6.3 or higher.

 * All Site Map wobjects will be migrated to Navigation assets 
	during the upgrade. All the site map templates will
	be lost. If you want them, save them before the upgrade. Also
	check your site after the upgrade for all site maps to make
	sure that they look the way you want them to look.

 * All File Manager wobjects have been migrated to File Folder Layout
	assets. The File Manager templates will be deleted during the
	upgrade, so if you want to keep yours, get them before upgrading.

 * If you have any SQL reports querying internal WebGUI database tables,
	you'll need to update them after the upgrade. Most of WebGUI's 
	database tables will be changed during the upgrade process.

 * If you have any custom page templates, they'll need to be updated
	to work with the new Layout system. The templates have been 
	changed significantly enough that automatic migration of them is
	not possible.

 * You may add optional protection for your uploaded WebGUI files. This
	will check the privileges of the files from the WebGUI database
	before sending them to the browser. To enable this you must use
	these directives:

	PerlSetVar WebguiRoot /data/WebGUI
	PerlRequire /data/WebGUI/sbin/uploadsAccessHandler.perl

	And then add this to each virtual host you wish to protect:

	PerlSetVar WebguiConfig www.example.com.conf
	<Location /uploads>
		PerlAccessHandler WebGUI::UploadsAccessHandler
	</Location>

 * If you have any custom code, please check out docs/migration.txt as
	there have been many changes to the API in this release.

 * There are many new components in this release, and as a result many
	tables. Here is a list of the new tables. Make sure you have no
	plug-ins installed that conflict with this, or tables you've
	created for your own uses: Collaboration, Post, Thread,

 * Due to the sweeping changes in this release the migration script may not
	work perfectly on your site. It should get you 90% of the way there,
	but it will be up to you to fix the problems it can't catch. Some of
	the things to look out for are Collaboration System (formerly USS
	and forum) templates. Also look at images and navigations as they've
	been moved from outside the content system, to inside it as assets
	in the new asset tree.

 * If you are using the SMB auth module, please note that it has been removed
	from this release. It has been long deprecated and is no longer an
	official part of WebGUI. It will be made available in the user
	contribs section of plainblack.com for people wishing to continue to
	use/maintain it.


6.2.10
--------------------------------------------------------------------
 * The recommended default location for the WebGUI log is now
	/var/log/webgui.log instead of /data/webgui.log

 * The default path for WebGUI backups is now /tmp/backups rather than
	/data/backups


6.2.8
--------------------------------------------------------------------
 * Due to a bug in the theme system, if you created any themes in any
	6.2.x version prior to 6.2.8 they will need to be deleted and
	recreated. Otherwise they will export a corrupt theme file.


6.2.2
--------------------------------------------------------------------
 * If you used 6.1.1 for a while, and feel like there's something
	wrong with your navigation or page tree, then there just
	might be. We corrected a rather large problem in the Page
	system that could have caused page tree corruption. To test
	and fix this problem, get the page tree tools from the user
	contribs area of plainblack.com. Be sure to back up your
	databases before using this tool.


6.2.0
--------------------------------------------------------------------
 * WebGUI now requires Time::HiRes to operate. Be sure to have it 
	installed prior to upgrading or the the upgrade will fail.

 * Parts of the WebGUI API have changed once again, so be sure that
	any third-party plug-ins you have installed have been updated
	to work with 6.2 before upgrading.

 * A new configuration option has been introduced: 
	exportPath = /path/to/export/dir
	If exportPath is defined in the WebGUI config file, a new 
	"Export" icon will appear in the page toolbar.


6.1.0
--------------------------------------------------------------------
 * See docs/migration.txt for changes in plug-in coding.

 * You no longer need Data::Serializer.

 * See docs/migration.txt for changes in the template system.

 * See docs/migration.txt for changes in the Internationalization
	and help systems.

 * If you're using any third-party plug-ins, you'll need to get
	updated versions to work with 6.1.

 * If you're using a language other than English on your current site,
 	you'll need to obtain a language pack from either the user
	contributions or one of the WebGUI Worldwide sites.

 * Each user's language has been reset to the default language for
	the site as specified in the profile settings.

 * We removed a bunch of the cryptic-hack code that was allowing
	backward compatibility all the way back to some 2.x, 3.x, and
	4.x stuff. To be sure that your site will still work, copy
	the gateway script (index.pl) over your old one. Also make
	sure you have extrasPath and extrasURL defined in your config
	file.

 * The ThumbnailLinker macro has been removed. You can now use the
	Thumbnail macro because it is templated.


6.0.2
--------------------------------------------------------------------
 * You need to add all of your site aliases to the sitename variable
        in your WebGUI config file.


6.0.1
--------------------------------------------------------------------
 * Apache 2.0 is now the recommended web server for WebGUI. As such
	sbin/preload.perl has been defaulted for use with mod_perl
	2.0. If you are still using Apache 1.3, don't worry, WebGUI
	will still work great for you. You just need to edit
	sbin/preload.perl to match your environment.


6.0.0
--------------------------------------------------------------------
 * As part of the upgrade process our scripts will attempt to
	migrate your styles, page, FAQ, Item, Link List, and
	SQL Report templates. However, the migration scripts are not
	perfect due to the wide-variety of templates out there, so
	you may need to update some portions of your templates
	manually.

 * The Authentication Module API has been completely rewritten.
	Please see docs/migration.txt for details.

 * The Paginator API has been significantly changed.
	Please see docs/migration.txt for details.

 * WebGUI now requires the following Perl modules to be installed:
	Data::Serializer
	SOAP::Lite
	Cache::Cache (no longer optional)

   WARNING: Be sure you install these modules BEFORE you attempt to
	upgrade or the upgrade will fail and you'll have a mess to
	clean up!

 * If you've created any custom Events Calendar templates, they will
	no longer work due to the new template structure for events
	calendars. Your old templates will remain intact, however,
	so that you can migrate them manually to the new template
	variables.

 * The Synopsis macro no longer exists. If you were using it to
	retrieve the current page's synopsis, then please use the
	^Page("synopsis"); macro. If you were using it to build a
	synopsis style navigation please use the new ^Navigation();
	macro.

 * The old navigation system has been entirely replaced. If you've
	built or are using any navigation components that did not
	come with WebGUI then you'll need to remove them and use
	the new configurable navigation system. See migration.txt
	for additional details.

 * The old realtime search subsystem has been replaced with the new
	indexed search wobject. As such, we've removed the ^?; macro.
	If you were using the ^?; macro then you'll need to set up
	a search wobject to replace it.
 
 * Themes that were created with 5.x versions of WebGUI will fail to
	import into WebGUI 6.0. Sometime after the release of 6.0
	(gamma) there will be a theme converter available on
	plainblack.com to convert your old 5.x themes into 6.0
	themes. If you've already imported a 5.x theme you have
	nothing to worry about. All of the theme components will
	automatically be converted to 6.0.

 * If you have any SQL Reports going against any USS, they will need
	to be updated as the USS tables have changed.

 * During the upgrade process you may see some database errors during
	the migration of SQL Reports. Don't be alarmed. Your upgrade
	has not failed. Instead, some of the queries in the SQL Reports
	may have failed and will cause the SQL Report templates to not
	be automatically generated.
