AW: Is it time to move to 2.0?

[Dominik Psenner]

1.2.11 already contained breaking changes and so did 1.2.12. Thus I would
not mind breaking backwards compatibility within 1.X even further. The next
good milestone could be 1.3 RC1 since we won't be compatible with log4j2 and
we should go to 2.X only if we port log4j2 features into log4net.
