- The text formatting is now fixed - you should be able to post any sort of HTML/PHP/Javascript code in there and not lose characters.
- The comments are displayed monospaced to further help readability of the text.
- Smileys work.
- CVS links, bug links and web links should all now just work automatically.
- There are also some instructions on-screen when adding a bug or a comment to an existing bug.
If you want to play with or test the changes please use Bug 2658.
