Comments & Antispam:
- Comments can now be deleted with a single click... no more javascript confirmation... no more wasting time when slaughtering spam.

- Comment feeds configuration. Comment feeds can now be disabled per blog. It's also possible to just include a small excerpt for every comment. (@sam2kb).

Blog skin design & features:
- Colorbox (jQuery Lightbox alternative) integration: clicking on images attached to posts will now automatically open a zoom window. When multiple images are attached to a post it's possible to start a slideshow. (@francoisplanque)

- Basic antispam plugin: remove repetitive characters and trim whitespace (@sam2kb)
Statistics:
- Improved search engine detection algorithms (@sam2kb)
- Better handling of regional character sets and "serp ranks".
- Search engines definitions moved to /inc/sessions/model/_search_engines.php.

Enhanced Skins:

  - Cascading widget params: overall defaults < widget defaults < container/calltime params < widget specific configs (saved in DB)
- Default widgets:

    - Public blog list : Display list of all blogs marked as public.
    - Same owner's blog list : Display list of all blogs owned by the same user.
