2.2 Release Note

These are the changes that have been committed for Version 2.2.

Server Connectivity

• Support for multiple pluggable server adaptors (ticket #250)
• Improved <<importTiddlers>> to allow tiddlers to be obtained from any server type (for example, MediaWiki? or Socialtext, as well as from standalone TiddlyWiki files)
• Added support for server synchronisation with the <<sync>> macro
• Added support for missing tiddlers to be automatically retrieved from a server
• New 'field' toolbar command that pops up a list of the extended fields attatched to a tiddler
• New 'syncing' toolbar command that pops up a menu showing the current synchronisation status of a tiddler and allowing it to be synced to a different server
• Added changeCount extended field to all tiddlers to simplify synchronisation (ticket #249)
• Extended 'contentPublisher' mechanism and renamed tag to 'systemServer'

Backstage

• Added "backstage" user interface to provide a consistent location for tools needed by TiddlyWiki authors (ticket #247)
• Added <<backstage>> macro that creates a button that jumps straight to a particular backstage tab. For example, <<backstage sync>>

Usability

• Added popup previews of tiddler contents in the <<plugins>>, <<import>> and <<sync>>
• Added ability to progressively reveal additional commands in tiddler toolbars with '>' (which renders as 'more')
• Added explanatory annotations for shadow tiddlers when in edit mode
• Extended <<allTags>> macro to allow tags to be excluded if they are themselves tagged with excludeLists
• Added <<options>> macro to automatically list all available config.options
• Improved message displayed by core code when the browser has JavaScript? switched off
• Improved error message for failed saving
• Added 'size' column to ImportTiddlers? and PluginManager? (ticket #298)

Performance

• New storage format using <PRE> to preserve white space
• Rearranged HTML file layout to bring the user content closer to the top of the file
• New 'DOM scrubbing' feature to deal with memory leaks. This will have a big impact on TW coding styles - it permits two useful techniques to be used safely:
  1. the use of closures to pass parameters to event handlers
  2. the storage of JavaScript? objects in DOM attributes

• Improved animation engine that adapts better to the performance of the browser
• Added new Morpher animator that allows for some cleaner, faster animations

Internationalization
