pari-2.11.3(STABLE) released |
Dear PARI lovers, I would like to announce the release of pari-2.11.3 (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: Bug numbers refer to the BTS at http://pari.math.u-bordeaux.fr/Bugs/ Done for version 2.11.3 (released 03/03/2020): [last column crossreferences current development release 2.12.1] Fixed 1- qfisom([16,6;6,10],[4,3;3,10]) was not 0.
