To see where Trac is going in future releases, see the ​Roadmap.

0.10.4

0.10.3.1

Trac 0.10.3.1 is a security release:

• Always send "Content-Disposition: attachment" headers where potentially unsafe (user provided) content is available for download. This behaviour can be altered using the "render_unsafe_content" option in the "attachment" and "browser" sections of trac.ini.
• Fixed XSS vulnerability in "download wiki page as text" in combination with Microsoft IE. Reported by Yoshinori Oota, Business Architects Inc.

0.10.3

Trac 0.10.3 is a bug fix release. The following list contains only a few highlights:

• Timeline fail to load with a "NoSuchChangeset" error message (#4132).
• Timed out MySQL connections not handled properly (#3645).
• Subversion repository resync broken. (#4204).
