Release Candidate for 3.9.1
I’ve packaged up WordPress 3.9 RC1 and intend to ship it Wednesday morning. For a complete list of the 33 issues, please see this report. Some highlights:
- Widgets: Theme preview empties sidebar on active theme. #27897.
- Multisite: Fixes regressions with uppercase characters in network paths; and with www as a subdomain. #27866, #27927.
- Header images: Fix weird behavior (or hiding) of various buttons: #28046, #27848, #27936.
- Performance: Fix potentially slow query on the new/edit post page. #27985.
- Various playlist, media, and editor fixes, including drag-and-drop text (#27880) and positioning of images when adding a caption (#27922).
- Some minor internationalization and RTL issues, like #27924 #27893 #27845.
Note this does not address a number of other issues, which are slated for a 3.9.2 release. Notably, many of these will require updates to TinyMCE, or require additional study or testing.
