Subject Re: [ANNOUNCEMENT] Apache Logging log4j 2.0-beta2 released
Date Sat, 13 Oct 2012 19:39:11 GMT
Hello,

I just forwarded this to announce@apache.org

I can only remind how important sending the release announcement to
announce@ is - let us add this recipient to our defaults for
announcments please :-)

In addition, I posted it to our blog.

Thanks for the hard work!

Cheers
Christian
