The few tests to look closer at seem to be: BIGNUM/PARI-200-5,
 I can also see a very slight preformance regression shown by the PI-*
benchmarks, nothing major

There was a problem with gnuplot. I was printing floating point numbers with the wrong exponent character and the plots got messed up. Now they should be ok: FFT is one of the benchmarks that improved most!
Is there an easy way for users to reproduce these benchmarks and
generate plots?  I remember that when trying some benchmark suite I had
some trouble to set it up, but it was a while ago.  It'd be nice to
have a comparision between official release versions too once the next
release it out.

It is a collection of hacks, plus fixes of Eric's benchmarks, so that they also run on ECL, catch errors, etc. I uploaded a tarball with the current version of those files here

This reminds me that the releases are rare, and that the CVS/GIT
snapshots continue to pretend to be the same version over long periods
of time, which is confusing when users submit bug reports

This only partially true. Right now ECL uses also the VCS (git) commit id to identify itself. This distinguishes the different versions and allows me to better find out what changes the user has.

OTOH, the release engineering problem continues to be that: a problem. The only reasons why there are no releases is because testing on all platforms takes time and the current infraestructure I have does not work well enough. See for instance how many of the platforms here have outdated tests: http://ecls.sourceforge.net/logs.html

Sage (www.sagemath.org) project perhaps might help with testing infrastructure.
(I"m not speaking for Sage here, although I think this will be welcome).
ECL is released as a part of Sage, and this happens on a regular basis (not on all platforms ECL supports though, but at least on a handful on different Linuxes and MacOSXs).
Juanjo, if you are interested in this, just post on sage-devel.
