Just Writing 3.5 is the first beta release of WordPress 4.1 support. There are a few notes on the WP4.1 support:
- There is no text mode editor at this time. Most of the code is in place to support it but at the moment switching between them corrupts the post so it has been disabled.
- Switching between the edit page and writing mode, unlike the old DFWM, requires a full page load.
- There are a few hard coded pieces around, so there may be some weird effects with non-english languages.
- At the moment, only editing the post title and body are supported, however the rest of the post meta data will be added over the next few releases after the base code is stabilized.
