pari-2.1.5 released

[Karim BELABAS <Karim.Belabas@math.u-psud.fr>]

Dear PARI enthousiast,

  this message is to announce the release of [long overdue] version 2.1.5 of
the PARI/GP system. The new release can be downloaded from

 ftp://megrez.math.u-bordeaux.fr/pub/pari/pari.tgz

This is a BUGFIX release for the stable version 2.1.4 and corrects a
number of minor annoyances. The only really significant items are Fixed-1, 3,
5 in the list below.

Also it is now possible to test against GP's version number in .gprc (#if
VERSION < 2.2.4, etc...), so it is now possible to use the same gprc for
stable (2.1.*) and unstable (2.2.*) branch, _and_ still use recently
developped features in the version that support them.

Have fun,

    Karim.
