TM4E 0.3.0 ships source code as a Git tag https://github.com/eclipse/tm4e/tree/0.3.0 and p2 repository for usage in the Eclipse IDE or in dependency management (target platforms) download.eclipse.org/tm4e/releases/0.3.0
No API was modified.
TM4E removed the "TextMate editor" that was present in 0.2.0. While some users may have been using it, it's know to be very low popularity and using the Generic Editor is a more recommended approach.
TM4E is internationalized using Eclipse NLS mechanism.
TM4E 0.3.0 is tested against Eclipse Platform 4.10. It probably works with older versions of the Eclipse Platform, but that was not tested.
Bugfixes
Remove useless "TextMate Editor"
