The current intro price will run until the end of the year.
The fixes for the current issues are being tested (rather a few days more than the previous hurry).
The loud noise issue was very likely in the EQ department, which has been rewritten in the last days (the processing part), with 64 bit processing; faster and more accurate as a side-effect.
The validation issue was the plugin blowing up the AU validator when it was told to process at 22.5 kHz. An internal downsampler was switched on to up-sample - not anticipated buffer overruns, but easy to fix.
Emailing issues from the website will hopefully be fixed now I am switching to Mail Chimp, not in the first place for marketing emails, but for the so-called transactional emails (confirmation, download links).
Even with quite some convolutions being calculated, the processing should still be light. On a medium i5 laptop I have used 16 instances (all mics) for a demo, at 50% CPU in Reaper. I advise proper routing with groups and not to add so many full length reverb tails.
TIP: if you set a reverb channel's tail to zero, it will stop calculating the tail part after 2 seconds. The mute can't do that, as you would miss reverb when you toggle it back on. This was meant for positioning-only. I will be made a more understable setting in a next version (so, one toggle for positioning, making processing extremely light).
The late December update will have an option for enabling the multi-threading (which is off in the first releases), making calculations even lighter. Another option will be the first lossy computations option (there are more eggs in the basket, but not all will be added at once).
