It is a work in progress and I have never heard any mention of specific release or finalisation dates for any sme releases for the very reason that no one knows, until when it is ready !
We're hoping 7.0 isn't too far off, but we can't commit to a timetable. Everyone is doing this in the time they have available.
7.0alpha26 is looking very good indeed. Most of the bugs in the bug tracker have fixes, but there are a few important ones which still need to be squashed. If you think you can help, please look through the bug list:
https://sourceforge.net/tracker/?group_id=96750&atid=615772I've been running 7.0alpha for some time, but you should only do so if you know what to look for, will report bugs in the bug tracker, and ideally could help investigate how to fix them. We don't need code for that, but someone else spending time Googling really helps. Clear bug reports are wonderful. Ones with pointers to fixes are gold.
There are lots of ways people can help - bug reporting, testing fixes, documentation, spreading the word, contributing/releasing code to expand the product.
If you can, please give 7.0alpha26 a run. But, please check the bug tracker, and remember it's called "Alpha" for a reason - bugs are expected in Alphas. Please, please, only reports bugs in the bug tracker linked above - it's the best use of our limited development cycles.
