= Release Notes for Trac [milestone:0.12] ''Babel'' Release =

[[PageOutline(2-3)]]

== Highlights == 
 * [trac:wiki:TracL10N Translation] of Trac in your language,
   using [http://babel.edgewall.org Babel].
 * [TracRepositoryAdmin Multiple Repository Support] per environment
 * Improved Wiki, more powerful syntax and nicer user interface with 
   automatic preview in side-by-side editing mode
 * Improved Ticket user interface, with editable comments and 
   automatic preview


== Detailed User Visible Changes ==

=== Wiki ===
 * Wiki user interface
   - show ''Last Modified ...'' link on the upper right side of the page
   - show clickable wiki page name path on the upper left side of the page
   - [http://www.universaleditbutton.org/Universal_Edit_Button Universal Edit Button] support
   - improved wiki preview
     - normal mode, with the editor on top of the preview
     - **side-by-side mode** with the editor on the left side,
       along **with automatic preview** on the right side
   - attachments are listed in a collapsed section
 * WikiFormatting improvements:
   - lists can now start right at the beginning of a line
   - improved WikiCreole compatibility
   - better '>' quoting support, arbitrary wiki text can now be quoted and
     still renders correctly
   - much improved pipe-based syntax for [WikiFormatting#Tables tables]
     (support for headings, column spans, cell alignment)
   - added several new [WikiProcessors wiki processors]
     - `#!td` and `#!th` for building complex tables with arbitrary wiki 
       content
     - `#!htmlprocessor` for embedding HTML comments in rendered pages
   - more direct help for macros (`[[?]]` gives a short list of all macros 
     and `[[macro?]]` provides help for the given ''macro'')

=== Ticket System ===

 - comments are now editable (a.k.a. #454) with automatic preview;
   you can also see previous versions of the comments and what has been changed
 - nicer comment preview (positioned closer the the comment editor, 
   no longer on top of the ticket box, and automatic preview as you type)
 - collapsible attachments, change history, and ticket modification sections 

==== Roadmap and Milestone ====

 * In the roadmap, milestones without due date can be filtered out


==== Reports and Custom Queries ====

 * Improved custom queries:
   - support for ''Created'' and ''Modified'' fields (even as criteria, see
     TracQuery#QueryLanguage)
   - OR'ed clauses (tickets having ''performance'' in description ''OR'' 
     ''performance'' in summary)
     - in the user interface
     - in query: links and ![[TicketQuery]] macro, for example:
        * query:?description=~performance&or&summary=~performance,
        * `[[TicketQuery(description=~performance,or,summary=~performance)]]`

=== Repository Browser ===

 * Show the Repository Index, in case more than one repository has been defined
 * Remember last expanded folder in the URL and automatically re-expand it
   when visiting that URL again
 * Separate sortable column for ''Author''

=== User Preferences ===

A new tab has been added for selecting the language.

=== Timeline ===
   - filtering by authors (space separated list, negation possible 
     by specifying -author)
   - filtering by repository, in case multiple repositories are defined
     (select either all repositories or a subset of repositories)


=== Caveats ===

 - This release requires a '''database upgrade''' when upgrading 
   from the 0.11.x series:
   {{{
   trac-admin $TRAC_ENV upgrade
   }}}
 - PySqlite 1.0.x is no longer supported; use PySqlite 2 (preferably 2.5.x)
 - PyPgSQL (Python bindings for PostgreSQL) is no longer supported; 
   use psycopg2
 - Text template processing has been changed from the
   [genshi:wiki:Documentation/text-templates.html#legacy-text-template-syntax legacy text template syntax]
   to the
   [genshi:wiki:Documentation/text-templates.html new text template syntax].
   Overridden text templates placed in the `templates` folder of the
   environment must therefore be converted to the new syntax (typically 
   the ticket e-mail template). 
   Also, the `[notification] ticket_subject_template` 
   [wiki:TracIni#notification-section option] can now include arbitrary 
   directives.

[[TracDev/ApiChanges/0.12]].


== Acknowledgements ==

Many thanks to the growing number of people who have, and continue to,
support the project. Also our thanks to all people providing feedback and bug
reports that helps us making Trac better, easier to use and more effective.

Without your invaluable help, Trac would not evolve. Thank you all.

Finally, we offer hope that Trac will prove itself useful to like-minded
programmers around the world, and that this release will prove an improvement
over the last version.

Please let us know. :-)
