Bloo Beta 2 has been released! You can download it here.

Here are the highlights:

• Refactored the loading of SnapOns, and unified their format. Now everything in Bloo follows a common SnapOn format, whether for core SnapOns, extension SnapOns, or theme SnapOns.
• Optimized the loading of SnapOns so that the system only loads the resources it needs, rather than loading everything
• Implemented the CTCode extension SnapOn. This is a spam checker that is quite effective against both trackback and comment spam, and that doesn't require the commenter to answer questions, type kaptchas, etc.
• Improved the administrative interface
• Created the Bloo Wiki SnapOn, which gives a blog certain Wiki-ish features (such as allowing the author to enclose post titles in [[ ]] brackets, which converts the entry into a link to that post title. Note: this SnapOn is not part of the core release. It will be deployed eventually on the main bloo documentation site (http://outofthebloo.com) soon.
• Created the ThemeDownload SnapOn, which allows the administrator to place Theme Download links on the blog which will contain the zipped code for the current theme. Note: this SnapOn is not part of the core release. It will be deployed eventually on the main bloo documentation site (http://outofthebloo.com) soon.
• Created "pend" type overlays, which will autmatically append or prepend themselves to specified overlays. Very handy for extending the Bloo interface.
• Improved the Comments interface
• Added Theme Screenshots to the administrative interface for Themes
• Improved the Theme administration panel
• Implemented Session messages, to provide a common facility for displaying information and warnings.
• Cleaned up and upgraded the Quicktags buttons, and added Quicktags to the comments form (optional)
• Added extension SnapOns that protect the user from losing unsaved changes to posts or comments if an errant back or close button is pressed.
• Added better security checks to prevent the unauthorized loading of a SnapOn.
• Added new themes: Lush, Jill, Quentin, Monochrome.
  
• Now administrators can associate a blog logo image to their blog.
• Theme Credits now can appear at the bottom of the main page
• Fixed general problems with the RSS interface
• Fixed the problem with Smilies not displaying properly in edited posts and comments.
• Fixed the problem with the PopularPosts extension SnapOn that had it counting removed spam comments in the total comments count.
• And performed a lot more behind the scenes enhancements and fixes.
