[rsyslog] rsyslog 4.4.3, 4.6.0, and 5.x

[BuraphaLinux Server]

Will there be an rsyslog 4.4.3 release?  I see references to changes
from it in the website, but cannot find the 4.4.3 release itself, and
the 4.6.0 release seems to say that there will not be any 4.x releases
any more.  The web page says 4.6.0 is a stable release and a beta at
the same time, which is very confusing for me.

The top says "Version 4.6.0 [v4-beta] (rgerhards), 2010-02-24" which
means it is a beta, but then the text on the page also says "This is a
new stable v4 version." and "Do not expect any more new developments
in v4.".   I'm a bit confused.  Does this mean if we want bugfixes we
have to run a 5.x version?
