Hi Martin,
Nice to see that you are following us closely ;-)
I can assume that you know that except for fixing bugs, there are a few other major things we did lately, right?
You probably noticed the new KB and the constantly extending Companion Kit tools, those tools require some effort and are curtail for complementing the product from the documentation, knowledge and education angles.
As for 6.4, it's rapidly progressing, and natively, the last issues that remained are more of a research type of issues and occasionally added issues. I feel quite wired to have to tell this to you, but we just finished the summer vacations period, I guess that this fact too had some effect on the speed of progress.
In general, I'm really satisfied with the thousands of issues we were able to solve and the large number of infrastructures we enhanced and created within v6.4 and this time we take it one step at a time with lots of testing and re-testing before we officially release v6.4.
Having said that, 6.4 RC1 is coming out very soon and the official release will be announced in no later than within a few weeks time.
I must point out that RC0a and all the more so the upcoming RC1 are completely usable, and fully supported for production usages. Despite the above, we truly appreciate your patience, and will keep on doing everything we can to boost RC1 and announce the official release as early as we can.
Cheers,
Itzik
