pari-2.15.1 (STABLE) released

[Bill Allombert <Bill.Allombert@math.u-bordeaux.fr>]

Dear PARI lovers,

I would like to announce the release of pari-2.15.1 (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 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.

For the first time, binaries for ARM-based Mac are available, thanks to the
hardware provided by the Sagemath project, donations made to
https://opencollective.com/sage_math, and technical support from William Stein.

  --------------------------

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, Aurel and Karim
