We finally released jDiction 1.0.0 for Joomla! 2.5 - 3.2. This release is not the end of development, its should be more a signal that its ready to use. Anyway installing jDiction should not lead to data loss, but can temporally damage your Joomla! installation like any other extension, so make always backups before upgrading.
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.
