This release contains lots and lots of bug fixes and a few new features. Here are some details on some of them.
We added a new forced_root_block option, this enables you to force TinyMCE to always place any non block elements at root level into a block such as a P tag or a DIV.
Google video and YouTube support is now built in to the media plugin simply paste a URL to such a resource into the URL field of the media plugin and it will setup everything for you. We have been thinking of making separate dialogs for external video files but this will have to postponed for a future release.
A new default_document option was added this option makes it possible to use TinyMCE in a cross domain environment. This is more likely to be used by larger sites or corporations and if you don't know what the problem is don't bother to use the option. smile
The core has been cleaned some by removing unused code blocks, rewriting lots of it and use simpler methods for property retrieval.
Apos/' characters are no longer encoded since they only need to be encoded if they are places in attributes using apos characters as their separator values and TinyMCE doesn't support such elements since 99% of the web don't use them.
A old but annoying bug regarding IE and the removal of width and height attributes has now finally been resolved. So now you can have tags like <img src="my.gif" width="100" /> if you like.
Removed support and logic for IE 5.0. That browser is just to old now days and companies like Yahoo are beginning to end their support for it anyway.
Anyway, thanks a lot for all bug reports and patches for this release.
