pari-2.9.5(STABLE) released


Dear PARI lovers,

I would like to announce the release of pari-2.9.5 (STABLE). The sources
and Windows and MacOS binaries are available from

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

This is a BUGFIX release for the stable branch. 
This release addresses 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 preleases.

Have fun,

  Bill and Karim

P.S: The Changelog:
