Thank you for your post.
It's weeks from now, but not too many. Initially, we planned to release version 6.9 much earlier. In fact it would have already been available at the moment. Then we decided to add quite a few important fixes and features - namely two-factor authentication. So it will take a while.
I had a total of about 8 machines that Windows Defender and Security Essentials had quarantined.
That might be the case, although Microsoft was very fast to fix the issue. We haven't been reported issues with Windows Defender since then.
We continue to send reports and communicate with a/v software vendors regarding false positive classifications. The problem is that nowadays almost all a/v software vendors heavily rely on machine learning algorithms which are very inaccurate. Alas, they don't care much about their customers who have to restore their lost data or installations after another erroneous detection.
