[Announce] [log4net] release 2.0.12

[Davyd McColl]

Hi all

I'd like to announce the release of log4net 2.0.12, which resolves issues 
LOG4NET-652 AND LOG4NET-653, both of which are related to correctly 
retrieving the username for the current thread, which would throw an 
exception on non-win32 platforms.

The site is up, nupkg is released, please can a member push artifacts the 
last mile to apache download servers. GitHub release is here: 
https://github.com/apache/logging-log4net/releases/tag/rel%2F2.0.12

Thanks
