I have moodle 2.5.1 that came with TinyMCE 3.5.8
I want to upgrade TinyMCE to version 4.0.7
are there any upgrade guidelines for this ? any tutorial or documentation ?
Moodle HQ are busy looking in to an upgrade of the editor - we may not settle on TinyMCE4, but we will likely share the code we create to test the different editors, so you could use that as a starting point to create your own editor plugin for TinyMCE4, if we select a different editor.
