Trac 0.11.7 (March 10, 2010)
http://svn.edgewall.org/repos/trac/tags/trac-0.11.7

 Trac 0.11.7 is nearly identical to 0.11.7rc1 except for a few more fixes:
  - avoid an infinite loop when using an AtomicFile in a read-only
    directory (#9081)
  - don't report client disconnects during writes as internal errors (#9103)
  - don't reuse a closed cursor, which could happen in one specific case
    for the pysqlite backend (#9104)

Trac 0.11.7rc1 (February 23, 2010)
http://svn.edgewall.org/repos/trac/tags/trac-0.11.7rc1

Security fixes:
 - Fixed a ticket validation issue that would allow unauthorized users to modify \ 
the status and resolution of a ticket (#8884)

Performance improvements:
 - Trac wiki had some trouble handling very long unicode words (#9025) \ 
[[comment(intentionally kept vague, we don't want to advertize a DOS, do we?)]]
 - Full text search was very slow if lots of custom fields were used (#8935)

Bug fixes:
 - Fixed a race condition that could lead to the destruction of the trac.ini \ 
file (#8623)
 - Fixed creation of new milestone which could have been a rename if performed \ 
after a name clash has been detected (#8816)
 - Fixed display of value 0 in report cells (#7512)
