The Nim team is happy to announce the double patch release of versions 1.2.10 and 1.4.4.
The crucial bugfix that demanded these releases is the rework of the SSL certificate handling; it is now performed correctly and also enabled on Windows. The 1.0.x line is not affected simply because 1.0 does not check SSL certificates at all. Please upgrade to either 1.2.10 or 1.4.4 immediately.
