Starting with 1.0 prerelease 0.9.9.4 we have Joomla 3.0 support added and many enhancements. Feel free to test and give as much feedback as possible. And as always make backups!
We released version 0.9 today you find the file in the download section. We would say you could use it in production, but it's in your responsibility for any problems that may occur. Always make backups.
In the pre-release 0.8.9.6 we added a really nice feature for translation offices. XLIFF is a file specification for translation need. More at the specification Website. We support 1.2 of this file format and we would be happy to get some feedback on this.
Please make backups before you updated your system. You will find it in the download section.
