I spent the greater part of the morning working on upgrading my Wordpress 2.02 TinyMCE from the default old version to the new TinyMCE 2.0.5 which is scheduled to be released with Wordpress 2.1. I’ve created a zip file that you can unzip over your wordpress installation that will upgrade your TinyMCE to 2.0.5.
I have only done preliminary testing and so far it seems OK but I’d highly suggest making a backup of your entire Wordpress folder just to be sure if you need to roll back.
I have tested this with the Gallery2 WPG2 plugin. There were some extra hacks I had to make in the tiny MCE code to make it backward compatible.
