pari-2.5.2(STABLE) released


Dear PARI lovers,

I would like to announce the release of pari-2.5.2 (STABLE). The sources
and a basic Windows binary are available from

  http://pari.math.u-bordeaux.fr/download.html

This is a BUGFIX release for the stable branch. It fixes a bug that show
up when compiled with gcc 4.7, and some all significant problems that could be
fixed in a simple, harmless way. However we strongly encourage you to upgrade
since it fixes a number of cases where PARI was returning an incorrect result.

Thanks to all those who reported problems, on the mailing lists or through
our Bug Tracking System. ( See http://pari.math.u-bordeaux.fr/Bugs/ ), or
who tested the prelease.

Have fun,

  Bill and Karim
