I checked SourceForge, and it does not contain the version.
I've tried the official Nuget repository, but that also does not have v1.2.11, neither the old key or new key.
I tried looking at the FAQ section, looked into Jiří Činčura's blog where he says he published a package for 1.2.11, and his blog links back to the official Nuget repo, which does not have a v.1.2.11.
Where would I find a safe, trustworthy binary for log4net 1.2.11? If I downgrade to 1.2.10, would I be missing out on bug fixes? I assume moving to 2.x contains breaking changes, so it doesn't look like an option.
