A new Beta version of WordPress 3.5 has been released, with several fixes and enhancements that are slowly improving implementation.
The Beta 2 of WordPress 3.5 adds a simple way to manage image galleries. You can drag and drop images to organize and edit subtitles with one click. This is part of the planned media renewal in WordPress 3.5 Beta 2.
There is also a new graphical interface for static front pages used by the Setup screen reading (Reading Settings). Finally, it has also added a new image editing API.
