Today we released Zarafa 6.20.9.

Some highlights of the 6.20.9 release:
- Fixed some (rare) memleaks in the server, mostly when errors occur.
- Fixed two rare server segfaults
- Fixed an attachment access denied error with Outlook XP and draft emails
- Fixed that HTML becomes plain text (during 6.20.9 beta's only)

The full changelog is available here:

The upgrade manual (of 6.20 final) describes most of the features and provides upgrade information for administrators. The manual can be found here:
