The release candidates for new Nim versions 1.4.8 and 1.2.14 are out.
Based on our limited testing, this should fix the antivirus problem on Windows encountered with Nim 1.4.6, but we would like you to try it yourself too and report back.
If you use choosenim, trying out the release candidate is as easy as choosenim #version-1-4.
Please try them out and report if you encounter any regression (not just antivirus-related).
Changelog: ORC bugfixes.
Moved to GCC version 11 to silence the antivir software.
I still have the issue with Defender. nimble, nimgrep and vccexe flagged as Win32/Uwamson.A!ml. I ended up building nim from source (using clang 12) which was easy (kudos on that one). Sorry I can't provide any useful information.
On the plus side, building from source demonstrate that nim compilation approach is really fast :)
