pari-2.11.4 (STABLE) released

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

Dear PARI lovers,

I would like to announce the release of pari-2.11.4 (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 a regression introduced in 2.11.3 that affected Sagemath
and other 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.

  -------------------------- 
 
We would like to dedicate this release to Peter Montgomery who sadly passed
away last February. Peter was a long time PARI developer and a number of
algorithms he invented are implemented in PARI, initially by himself in
most cases.

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

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

    1- [from 2.11.3] bnfisunit could return wrong sign [#2208]
BA  2- factor((x-1)*(x-y)^2) --> oo-loop                                   [F62]
BA  3- ellap could fail with division by 0                                 [F63]
