0.12 'Babel'

(June 13, 2010)

Trac 0.12 is a major release introducing i18n and multiple repository support as the most visible changes.

The following list contains only a few highlights:

• The user interface is translated in a dozen of languages, provided the [Babel:] package is installed
• Multiple repositories can be associated to a single Trac environment; the repositories can be of heterogeneous types (svn, hg, git, darcs...)
• Usability improvements for the Wiki, with a nice side-by-side edit mode with automatic preview
• Richer Wiki syntax, with much improved support for tables, partial ​WikiCreole compatibility and numerous smaller improvements
• Usability improvements for the Ticket module, with automatic preview of comments while you type and possibility to edit or remove them later
• Improved Custom Queries (time fields, multiple disjoint conditions, a.k.a. OR queries)
• Timeline filtering by user
• ... and numerous smaller features added and bugs fixed since 0.11!
