WordPress 3.2 was launched a little over a week ago. There were various server incompatibility concerns with JSON in that release. This is the primary reason for the speed with which the core team handled the JSON issue and made fixes to the dashboard UI and the twenty eleven theme in this maintenance release.
If you’ve already upgraded to 3.2, this update will be much faster, thanks to a new feature in 3.2 that only updates files that have changed, rather than changing all of your files. Because we recently upgraded our sites, this update will only take a few seconds.
This haiku includes a short list of things that have been fixed:
JSON is the administrator.
Edge cases are a little neater now.
The complete changelog may be seen here.
Now is the time to upgrade to 3.2.1!
