After releasing the 4.0 Beta 3 as a security release with the 3.9.2 version, WordPress 4.0 Beta 4 came out just two weeks before the 4.0 milestone release. This version covers over 250 changes, and some of them are below:
- A lot of fixes to the new floating TinyMCE editor, especially with the second column of boxes. So far, I have reported over 5 bugs with TinyMCE editor (one more left to report, damn!).
- Better handling of small screens in the media library modals. Plus, a bulk selection mode for the grid media library.
- Improvements to the installation language selector.
- Visual tweaks to the plugin details module and customizer panel.
If you find any bug, then don’t forget to file a ticket on the trac.
