Changelog

3.2 (2005.08.25)

Major Features

New dead-simple AJAX-powered installation/upgrade process (see screencast demo) which replaces mt-load.cgi and all mt-upgrade* scripts. Also eliminated the upgrade distribution since only the config file would be different.
Combined mt.cfg and mt-db-pass.cgi into mt-config.cgi. Shipping as mt-config.cgi-original so as to prevent overwriting when upgrading.
Introduced the new System Overview section which allows administrators to configure and manage aspects of the system across all weblogs
Introduced a plugin-based feedback rating framework which scores comments and TrackBacks upon submission on a scale from -10 (least desirable) to 10 (most desirable)
Introduced the auto-expiring Junk folder which contains all negatively-scored feedback received by the app and deletes it after a time specified in the weblog feedback configuration
Now shipping with a 3.2-compatible SpamLookup plugin. Stops spammers cold!
Added TrackBack moderation and editing like comments
Added comment/TrackBack master switches on both the blog and system level. These allow a user to shut off receipt of these items in one place.
Major rearrangement of the weblog settings. Humanized options and implemented better grouping.
Major overhaul of all listing pages. They are now optimized for bulk actions and consistent wherever they appear in the application. Items can be selected by clicking anywhere on the row and contiguous selection is possible with the shift key. The checkbox in the header bar selects all, none and inverse (with the shift key). Introduced display options for each listing allowing a user to customize their view. New filtering mechanism on all listings
Major overhaul of the search/replace functionality. One can now search not only entries, but comments, TrackBacks, templates, commenters and activity log. Much safer replace functionality. New context-sensitive search added to nearly every page of the application.
Introduced the system- and weblog-level plugin management pages allowing a user to enable/disable, configure and get information about all installed plugins. All functionality works with MT 2.x plugins as well!
Implemented much simpler template code for the individual archive page, especially with regards to comments and TrackBacks. Moved most TypeKey logic to the site javascript.
Introduced the new MT 3.2 default stylesheet: "Vicksburg".
Implemented the standard Six Apart HTML structure which enables all MT users to easily share dozens of gorgeous styles created for TypePad and LiveJournal by just switching out the CSS.
Introduced the TemplateRefresh plugin, bundled with 3.2. which performs backup of single of multiple templates and refresh of those templates from the defaults. This can be triggered from either the template listing screen or the system overview weblogs listing.
Major overhaul of the commenter listing screen and introduction of the individual commenter record which lists information about each authenticated commenter and all of their comments.
Added a Trusted state for authenticated commenters which allows a commenter to bypass the junk mechanism. This can also be used on the weblog side to highlight valued contributors and (with a little ingenuity) give them special abilities on the weblog side.
An entirely new Live User Manual written from scratch by Tim Appnel powered by Movable Type and which includes user comments on every entry. More details here.
Opened up the Movable Type Knowledge base to all Movable Type users. Previously this was only available for paid licensees.
Major improvements to the Activity Log including pagination, display options, reverse-chronological sorting and CSV export.
Revamp of the main MT menu including more links to the places you want to go, weblog sorting by title, date of creation or date of last modifcation
New multi-category selection widget enabling very easy selection of secondary categories. Also present on the quickpost page.
New archive file path controls for mapping templates to archive types. Now includes many common archive maps in a simple dropdown and shortcut specifiers for making your own. MT template tags are still supported.
Introduced the basename field on the edit entry and Quickpost pages which allow users to specify the filename of the individual archive file. This allows for nice filenames that do not depend on the entry title.
Added dynamic publishing support for PostgreSQL and SQLite databases
Implemented outbound trackBack control enabling administrators to restrict (by domain or IP) where TrackBacks can be sent and auto-discovery is allowed. Admins can also specify whether or not to TrackBack entries on the same weblog.
Added itemset widgets (the dropdown on the right side of all listing screens) which contain secondary native actions and can be extended by plugins to provide extra functionality.
Revamped the template listing screens providing much better information at-a-glance
Added the default_templates folder containing all default Movable Type templates added to new weblogs. These templates can be customized to affect the default templates for new weblogs.
Easy mini-wizard TypeKey authentication setup allows you to easily and quickly enable TypeKey on your blogs.
Enhanced the "Remember me" checkbox on the comment form to remember not only form details but TypeKey authentication status
Added new gorgeous color icons which boost your blogging productivity by enabling you to stare at the Movable Type interface for extended periods of time without tiring.
Added Save & Rebuild functionality to the template editing page
Implemented System administrator and Blog administrator permissions and removed problematic blog-level "add/edit authors" permission

Developer features

Introduced easy plugin configuration integrated right into the application doing away with the need for most plugins to write CGIs
New MT::Bootstrap module implemented to make it easier to create CGI scripts which work with Movable Type
Implemented binary data support in PluginData for PostgreSQL allowing those users to use plugins which store PluginData
PluginData now uses MT::Serialize instead of Storable. PHP can also access PluginData now (although it's read-only)
Added pre_run, post_run callbacks to MT::App.
Now storing a permanent Atom ID for each entry
Now setting ID attribute on body tags of application screens to __mode for cool and interesting CSS/Greasemonkey foolin
Made MT directory discovery more robust (under both UNIX and Windows)
Plugin lib directories are sucked into @INC automatically by MT upon plugin directory scanning obviating the need for pesky relative use lib statements
Enhanced DBM objectdriver to accept both a limit and range/range_incl arguments.
Upgraded Smarty libraries to Smarty 2.6.9.
Added MT and MT::App methods for accessing configuration, query parameters and session data.
CMSPostEntrySave is now invoked after saving each entry through poweredit.
Plugins can now use AdminCGIPath
Now handling relative paths in the mt-config.cgi much better by converting them to absolute paths before use (based on mt_dir).

Usability features

Now building out the entire blog path upon saving if it hasn't already been created and the parent directories are writeable. If it's not writeable, a useful error is presented.
The weblog site directory is created if it didn't already exist when creating the .htaccess file for dynamic publishing.
Compiled templates directory (templates_c) is created with open permissions, when possible.
All static files are now in mt-static folder in the MT directory which makes installation/upgrade easy for those who need to move their static files out of the cgi-bin.
Comment form now disappears on published blog (after rebuild of mt-site.js) when comments are turned off on system or blog level.
Retired Closed status for comments and changed comment status dropdown to a checkbox.
Eliminated nearly all popup windows in the application
Added 'show_all' parameter for search/replace, which is useful when you want to see all items in a particular date range.
Added comment and ping permalink anchor notation in default templates: comment-<id>, ping-<id> for Six Apart style support. Legacy comment/TrackBack permalinks still supported in default templates but deprecated.
Implemented safeguard against deleting parent categories. Must delete subcategories first.
Now beautifying published links by stripping index page names (ie, "index.html"). Added optional with_index attribute to all link tags to preserve the filename.
Switched to Windows linebreaks in the mt-config.cgi because they are universally compatible. Notepad fans: Rejoice!
Now including an "import" folder in the default distribution
Categories are now shown with hierarchy in the "Assign Multiple Categories..." popup

Performance improvements

Many, many fixes which improve MT's mod_perl compatibility and performance (Thanks Tweezerman!)
Removed calendar from the main index template because it's a CPU hog. Code will retire to the documentation.
Implemented caching for ID-based lookups at ObjectDriver level
Added caching for plugin config objects.
Added support for HTML::Template file cache.

Error and exception handling improvements

Better error messages across entire application (missing config file, quickpost with no weblogs, invalid Site URL, etc)
Added fatal errors for failure to write to DataSource directory or failure to lock files.
Improved reporting of unwritable/uncreatable templates_c directory when enabling dynamic publishing.
Now producing a useful error message if the directory containing a SQLite database isn't writeable by the web server.
Now checking for the minimum required version of the "DBI" module (v1.21). Implemented better handling of DBI module requirement and reporting when it's unavailable.
No longer allowing ".." in Site URL because it's illegal in URLs
Template errors are now reported when publishing an entry
Category-archive tags no longer cause errors in rebuilding when category archives are disabled
Rebuilds no longer fail silently after saving an entry if a problem exists in your templates (for example, mismatched tags or a missing include module).

Template tag additions/deprecations/changes

Now shipping with the new Atom 1.0 feed template. No longer shipping with an RSS 1.0 feed template.
Now allowing disabled archive_types in ArchiveList which can be used for grouping entries, for instance, by week even if weekly archiving isn't enabled.
Added MTIfStatic and MTIfDynamic template tags, for checking which style of publishing is in use and using these to differentially build and display the sidebar content on all archive pages.
Changed Author Nickname to "Display Name". Added MTEntryAuthorDisplayname, MTEntryAuthorUsername. MTEntryAuthor and MTEntryNickname are deprecated but aliased to the new tags.
MTSubCategories contained tag now admits top="1" parameter to list all categories, even on a category page.
Added a template container tag, IfRequireCommentEmails, which prints its contents if email address is required from commenters.
Made the monthly archive block conditional now that the archivelist tag can function whether the archive type is enabled or not (archivelinks would still fail though, so the conditional is necessary).
Removed email address from Atom feed
Aliased the deprecated EntryIfCommentsAllowed directly to IfCommentsActive tag to address a disparity between the two.
Added MTCommentsHeader/MTCommentsFooter tags
MTIfNonZero and MTIfNonEmpty can now be used to test tags which require attributes. For example:

<$MTSetVar name="myvar" value="1"$>
<MTIfNonZero tag="MTGetVar" name="myvar">
Tag is evaluating properly
</MTIfNonZero>
<MTIfNonEmpty tag="MTGetVar" name="myvar">
Tag is evaluating properly
</MTIfNonEmpty>

Configuration file changes

The config directive HelpURL- is now the base URL for the help links in the app as well as documentation. HelpURL will be set by default to point to the User Manual Six Apart website, but of course can be changed to point locally.
Added IndexBasename configuration directive for defining the index page basename (see previous feature). Default setting is "index".
Added an MTConfigFile tag which is now used in building the mtview.php script.
Added WSSETimeout configuration directive to control the Atom WSSE authentication timeout window (default is 120 seconds).
Added UpgradeScript, MTAtomScript configuration directives which point to the respective scripts (defaults is mt-upgrade.cgi and mt-atom.cgi respectively).
Added WeblogDefaultTemplates configuration directive to specify the location of the default template directory (default is default_templates).
Added DBPassword directive as a replacement for mt-db-pass.cgi
Now forcing database setup upon initialization instead of assuming a default of BerkeleyDB (./db) because it's the least recommended choice of databases.
Introduces IdentitySystem directive which makes it easier to set up alternate TypeKey-compatible auth systems

Internationalization/Localization

3.17 (2005.06.02)

Once an entry or category has been set to receive TrackBack pings, disabling pings for it through the UI will not actually refuse pings to that item but will suppress display of those pings.
Rebuilds will fail silently after saving an entry if a problem exists in your templates (for example, mismatched tags or a missing include module). An error will be shown, however, upon manual rebuild using the "Rebuild Site" functionality.
The nofollow plugin will cause a spurious warning for users with older versions of Perl upon running mt-check.cgi, mt-testbg.cgi or any of the mt-upgrade scripts. This warning can be safely ignored.
Upon originally selecting a Creative Commons license, version 1.0 of the licenses are provided. Upon subsequent edit, version 2.0 licenses are provided.
Movable Type can't be used with DBD::Pg 1.4 because of a bug in that version of the database driver.
Plugins that need to save configuration data cannot be used with the DBI::postgres driver (mt_plugindata.data column has incorrect type).
When using MySQL 4.1, "modified" date strings will be mangled--for example, the output of the <MTEntryModifiedDate> tag is incorrect.
When a template is linked to a file, changes to the file are not written to the database until the user views the template and hits the "Save" button. As a result, when using dynamic pages, changes to the file are not reflected on the dynamic pages until the user saves the template.
Categories are shown without hierarchy in the "Assign Multiple Categories..." popup.
It is impossible to create two categories with the same name, even if they have different parents (on MySQL, PostgreSQL, or SQLite).
The recently_commented_on attribute to MTEntries may not function correctly when the MTEntries block is nested in a constraining block such as MTSubCategories.
It is impossible to produce files with no file extension by using the "File extension for archive files" box.
When a thumbnail is generated for a GIF image with animation, the thumbnail appears broken.
Under Windows XP (with IIS), the TrackBack URL that is displayed by <MTEntryTrackBackLink> does not work without further server configuration. For instructions, see "Configuring TrackBack on IIS Servers" in the TRACKBACK section of the Movable Type manual.
Better error checking disallows blank names in new categories, but they are still allowed when you edit and save an previously existing category.
If a post contains the URL of a large binary file (such as an image or a music file) and TrackBack auto-discovery is on, saving the post may fail.
If an error occurs while run-periodic-tasks is running, an entry may be put into "Published" status but not rebuilt.
On some versions of IE, after "maximizing" the QuickPost window, the entry text are may appear wider than the window itself, obscuring the scrollbar.
When importing or exporting a weblog, unique IDs in Atom feeds may change.
<MTComments> with lastn attribute produces an error message on dynamic pages.
When a reader submits the "Mail This Entry" form, no confirmation is displayed.
Clicking "Go Back" in a pop-up rebuilding window only re-tries the last group of pages upon which a rebuild was attempted, rather than taking the user back to a previous choice. On full-page error messages, "Go Back" does return the user to the screen where the action was taken.
After the first weblog, additional weblogs have category archives off by default, even though the default templates have category archives listed on the main index.
TrackBack pings received from a site using a different character encoding are displayed incorrectly.
<MTEntryBasename> isn't yet supported in dynamic templates.
<MTCalendarCellNumber> isn't yet supported in dynamic templates.
The new "locale" attribute for <MTBlogLanguage> returns a value in dynamic templates that is inconsistent with its return value on static templates.

3.17 (2005.06.02)

Fixed problem where MT installs at the root of a domain would continually log out the user.
Fixed a bug in nofollow which causes HTML sanitization of everything within an <MTPings> block.
Fixed a bug in mt-db2sql.cgi which caused it to fail in certain situations when subcategories are in use before conversion.
Fixed URL-encoding of uploaded file paths (e.g. images%2fbeach-pic.jpeg)

3.16 (2005.04.13)

Security

Made several important improvements with regards to application authentication and security.

Notifications

Fixed ``Send Notifications'' feature for multiple recipients.
Fixed a bug where comment notifications weren't being sent for some moderated comments.

Error checking

Improved validation of user input in many places. Leading and trailing whitespace is trimmed from author names, category names, and blog names. None of these can be left blank except for a known issue with editing the name of a previously existing category. Duplicate items are now disallowed in several areas.
Authors can no longer delete their own accounts, which could result in disabled installations.
If configuration of remote authentication is incorrect, error is reported when rebuilding instead of on the published site.
Fixed a bug where commenters were prompted to log in to a remote authentication service, even though registered comments were disallowed (if ``remote auth token'' was not blank). This fix only applies to new blogs.

User Experience

Fixed a bug with TypeKey authentication under IE when blog is published in UTF-8.
Number of items per screen in listings (e.g. ``Show 5 comments, 20 comments, ...'') is now persistent for each user.
Throughout the application, when a listing screen is filtered, the UI now displays the active filter parameters.
Wider use of background tasks for rebuilding, to make interface more responsive.
``Go Back'' button goes back to the screen from which you performed the initial action.
Added a ``Cancel'' button to preview screen, which returns the user to the entry listing screen.
Authenticated commenters' e-mail addresses are displayed on the comment editing screen, when available.
Comment listing now links to authenticated commenter's profile page.

Templates and Publishing

Default feed templates now use <MTBlogLanguage> tag, where applicable, to identify the blog's language.
Improved the HTML sanitization function in comments or any template tag that uses the sanitize attribute.
Fixed a bug where <$MTCategoryCount$> included ``draft'' entries in the count.
By default, <MTEntryAuthorLink> and <MTCommentAuthorLink> tags no longer display commenter's email address (currently applies only to static rendering).
Improved correctness of encoding filters (e.g. encode_js, encode_url, etc).
Fixed a bug where categories could not be sorted in ascending order on weblog pages. This now works in both directions.
Autolink URLs now recognizes https URLs in static pages.
The use of brackets in template names no longer causes an error.
By qualifying the category name with its ancestors, <MTEntriesWithSubcategories> tag can now select entries within a precise (sub)category, even if two categories have the same label.
Fixed comment preview to respect the ``Allow HTML in Comments'' setting.
Default templates now show full depth of subcategory hierarchy.

Configuration

After updating the weblog archive configuration, the user is now prompted to rebuild.
Added support for Creative Commons 2.0 licenses. More information about Creative Commons can be found at http://creativecommons.org/.
Added support for suppressing nav-commenters.gif publication based on new mt.cfg configuration setting ``PublishCommenterIcon'' (default value is 1).
Improved the application's ability to guess the desired weblog URL and filesystem path in new weblog setup screen.
Comment configuration now defaults to a safe and error-free configuration: Registered comments are not enabled and unregistered comments are moderated.

Internationalization/Localization

dirify now works with UTF-8 blogs as well as Latin-1.
When a category name is all non-Latin characters (or all punctuation!) the numerical ID is used as its ``dirified'' form.
Added localization support for weblog search.
Fixed a bug where new blogs and authors would default to an unexpected language.
Internationalization of default template names is now more consistent.

Dynamic Publishing

Fixed bugs which caused <MTArchiveCategory> and <MTCommentOrderNumber> to produce nothing,
Fixed a bug which caused <MTArchiveDate> to produce nothing when used inside <MTArchiveList>.
<MTSubCategories> now displays empty categories,
Fixed a bug where URLs weren't being autolinked in comments when the blog was configured to do so.
Fixed a bug where <MTCalenderIfToday> was not correctly detecting the date.
Dynamic pages can no longer be enabled if certain underlying system requirements are not met (i.e. MySQL).
On setup of dynamic rendering, Movable Type tries to create most of the pieces it needs (.htaccess, compiled-templates directory) on its own. Better error messages help the user create these pieces when Movable Type doesn't have sufficient rights.
Fixed a bug in which, given a large number of entries, rebuilds may time out when using dynamic templates (under dynamic publishing the FileInfo table is rebuilt, instead of pages on the filesystem). We are now doing these ``rebuilds'' in stages to prevent timeouts in the browser.

Entry Creation/Editing

The weblog dropdown on the QuickPost screen is now sorted alphabetically.
Fixed keyboard formatting shortcuts for Internet Explorer and Mozilla FireFox for the entry editing screen and the QuickPost screen.
Improved subcategory hierarchy display in the interface. Subcategories are displayed hierarchically in the following places: the Primary Category dropdown on the New Entry, Edit Entry and Quickpost screens, the category filter dropdown on the List Entries screen, the category filter and assignment dropdowns on the Power Edit screen and the popup category creation window.
QuickPost bookmarklets with lots of options no longer overflow the URL size limit in Internet Explorer 6.
Fixed a bug where the permalink of a post changed when saving from the ``Preview'' screen.
Added option in entry editing screen customization to display entry edit page action buttons at both top and bottom of the page.
Uploading files handles temp file creation error more gracefully.
TrackBack discovery is now more forgiving when domain name is mismatched (ie, 'www.example.com' and 'example.com').

Server Environment Compatibility

Fixed a bug under Windows servers, where links to plugin configuration pages contained bogus path information (e.g. plugins/C:\something\myplugin.cgi).
Improved handling of uploaded files and images and creation of thumbnail images on Windows.
File upload dialog displays Windows paths properly.
Fixed a bug when running under mod_perl that caused a spurious error message (``The uploaded file is too large.'') to be displayed on alternate requests.
Added support for SQLite 3 by routing around a bug in the DBD::Sqlite driver which prevented our timestamps from being stored.
DateTime Perl module is no longer required, which improves compatibility with more environments.

Developers

Fixed MT::ObjectDriver::DBI's count_group_by method.
Clarified application-template search path: app templates can now be overridden in more ways.
Fixed bug with SQLite 3 driver and storage of binary data from plugins.
Fixed a problem in the MT schema for PostgreSQL which allows plugins to store config data in PluginData (using BLOB). Because this required a schema change, this only applies to new installs. An upgrade script will be provided in the next release which fixes this problem for our current customers.
Added more comprehensive documentation for utility routines that can be used by plugins.
post_save callbacks now have access to the original object as well as the object which was saved.
Better defaults for MT::App subclasses make it easier to create a plugin with a UI. Example ``Mirror'' plugin (which has been updated for this release) demonstrates this.
Improved discovery of MT directory and active CGI working directory makes plugin UIs compatible with more environments.
Added support for a new DebugMode. Setting the DebugMode configuration parameter in mt.cfg to ``1'' can enable/disable unsightly warning messages. (Defaults to off).

3.15 (2005.01.24)

Closed an exploit that allowed an attacker to send mail to an arbitrary address.
Disallow any email addresses that contain newline characters.
MT::Mail now converts newlines in mail headers to simple spaces.

3.14 (2004.12.20)

Unnecessary rebuilds upon comment moderation are eliminated.
Generation of internal bookkeeping data for dynamic pages is not performed when using static pages.
New weblogs default to having comment moderation enabled.

3.12 (2004.10.19)

Rebuilds are faster due to caching some data.
Fixed ``The uploaded file was too large'' message when running under mod_perl.
Resolved some compatibility issues with perl versions before 5.6.0.
We now create an .htaccess file upon enabling dynamic pages.
<MTEntryModifiedDate> was returning creation date.
Fixed error reporting problems for template & plugin errors.
> and < Comment previews no longer show in the text-entry area.
Scheduled posting would only post one of many new entries on an archive page.
More robust upgrade script for PostgreSQL users, users of dynamic pages.
Default to use full entry body in RSS feeds.
A new template's dynamic/static setting is set correctly.
Duplicate sibling category names are prohibited.
Support for binary columns in PostgreSQL (enables some plugins that didn't work in that environment).

3.11 (2004.09.03)

Correct some problems with upgrades: from 3.0x to 3.1x with Berkeley DB, or from 2.6x to 3.0.
Updates to templates were not reflected on dynamic pages after saving an entry; that's now fixed.
In some older versions of Perl, a syntax error blocked any use of the application.
Category paths (e.g. ``Mammals / Primates / Orangutans'') were being omitted on some blog pages.
