I just sent you a pull request over at GitHub and updated all the things.
- Update to latest bbPress r4754 code changes
- Added README.md
- Updated bbpress-functions.php
- Updated bbpress.css
- Added custom CSS changes to bbpress-rtl.css
- Removed unused templates
bbPress r4754 is at this stage bbPress 2.3 Beta 2 and I am pretty sure any other changes we make before releasing 2.3 won’t affect any of what I just updated.
There are no changes to your code, just the bbPress updates to the latest version available.
