The fact that there is a section of the forums called 'FreeNAS 8' does NOT mean that it only relates to 8.x. The forums have NOT been updated to reflect that we are indeed on 9.x.
There is not enough of a difference between 8.3.x and 9.1.x to warrant an entire new section of forums....good god, we would double the amount of useless sections and posts if we did that.
Please simply ignore the 'FreeNAS 8' banner above the door, it was merely an indicator/deterrent (that obviously didnt work for all that came in here) to the ones that came in looking for the new version of FreeNAS .7, which literally has nothing to do with FreeNAS/iXSystems.
So, Alfred. In answer to your question, no, FreeNAS 8.3.x is NOT an old project. It is still openly supported here.
If you came in asking about FreeNAS .7, you would be kindly shown the door. ;)
