In short, RPM 4.11.1 release candidate 1 is out for testing:


While we haven't typically bothered with alpha/beta/rc stages with 
maintenance updates to stable branches, the number of changes here is 
somewhat larger than usual for a maintenance update ...  so to play it 
safe, starting with rc1. Unless something dramatic turns up, I'm 
expecting to simply rename this to 4.11.1-final in a couple of weeks 
time, but knock wood.

In addition to the usual assortment of more or less minor / corner-case 
bug fixes, the big thing here is macro- and spec parsing performance. 
You can (reasonably :) ask who cares about spec parsing speed, but with 
monsters like Fedora's > 300k line texlive.spec on the loose... it was 
always slow, but with rpm 4.11 it regressed beyond tolerable due to bad 
interaction between string pools and braindead code. The numbers speak 
for themselves, these are 'rpmspec --parse texlive.spec' timings from 
unoptimized builds on my laptop:

rpm   15.6s
rpm   32.8s
rpm 4.11.1-rc1:  3.2s

This involved some fairly heavy surgery in librpmbuild and the macro 
performance work from Alexey. I'm not aware of any regressions but... 
hence the rc. The things to watch out would be oddities in macro 
behavior and overall spec parse results, dependencies in particular.
