2.0.21
The change to run the Windows service as NT AUTHORITY\NetworkService
has been reverted, as it was reported to break logging (Windows only).
There are no other changes. If you are running version 2.0.20 on non-Windows platforms, or if you installed the service yourself, upgrading is not necessary.
Oh, and if you know how to switch back to NT AUTHORITY\NetworkService
and still have the ability to write log files, your help would be welcome.
