b2evolution 0.9.0.11 aka "Paris" bas been released. You can get it from the downloads section.
Why "Paris" you might ask? Well that's because I live nearby the city of light again... ;)
The meat of the new developments has now gone to the 0.9.2 branch, so this is only a service release focused on first class stability and includes the most complete language files ever. It also includes a few other enhancements which were easy to port back from 0.9.2.
This is a recommended upgrade for best stability and security. Moreover, a few little enhancements might make your life easier... (and no, 0.9.2 won't be here next week and no it probably won't be as stable and as secure as this one! :P)
Changes in "Paris" include:
New locales (fi-FI,en-NZ)
Updated locales (it-IT, zh-TW,ja-JP...)
Antispam blacklist checking: (fplanque)

Minor bug fixes
No configuration/database/skin update is necessary if you upgrade from 0.9.0.10,
EXCEPT:
if you use weekly archive mode, you will need to update the archive list displaying in your skins. In this case, the minimum is to update /skins/_archives.php .
Also, some new features will not be available without updating the conf (files in /conf folder).
