ANNOUNCE: Version 4.21 released

[MW Mike Weiner (5028)]

Would it be appropriate to use the RPM to upgrade an existing 4.20 install
that was done via tarball?? And if so, what "gotchas" should i be looking
out for? 

Things are running pretty well, but it seems that there are some "features"
in 4.21 that i can use.

I used the install.sh script for the installation of 4.20 out of the
tarball, which i have appeneded to this message, in case anyone wondered
where things were installed in the previous version. In other words, i am
not using the PREFIX of /opt for this install, rather the directories as
spelled out in the attached install.sh script provided with 4.20. 

I just want to make sure the RPM will not break whats already working!!

Any help would be greatly appreciated.
