WordPress 3.3 should be released somewhere in November this year. One change in the API that interests me most is improved Editor API. According to a post on WordPress development blog new API will allow to use TinyMCE anywhere.
WordPress Editor API. This is an updated API for both TinyMCE and Quicktags that outputs all parts of both editors in the same way as used on the Add / Edit Post screens, #17144. Plugins will be able to use the WordPress editor anywhere including the Visual/HTML tabs and the links to upload files and show the media library.
By anywhere i understand it will be both frontend and backend, if so then i will be able to implement WYSIWYG in WPJobBoard 3.5 for job description (and maybe some custom fields). There are already few examples how the new editor API could be used and i must say it looks really promising, but let’s wait for final WordPress 3.3 release.
