Fixed in this release is a bug that affected a ton of WordPress installations, the Script loader failing on no-JSON PHP servers. I had written up a fix in Help: WordPress broke after 1.3 Upgrade.
Other fixes in this release:
- Multi site upload limit fix
- Widget count on dashboard fixed
- Never show two flyouts at once
- userdata not workign properly
- Toolbar warning messages
- Unwanted backalshes in output
- Users could change logged in “Administrators” to “Subscriber” (Yikes!)
- … and a few more.
If you had to install the Hotfix 0.8 plugin, you should definitely get this minor release installed.
