pari-2.5.2(STABLE) released |
Dear PARI lovers, I would like to announce the release of pari-2.5.2 (STABLE). The sources and a basic Windows binary are available from http://pari.math.u-bordeaux.fr/download.html This is a BUGFIX release for the stable branch. It fixes a bug that show up when compiled with gcc 4.7, and some 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 prelease. Have fun, Bill and Karim P.S: The Changelog: [last column crossreferences current development release 2.6.0] Done for version 2.5.2 (released 20/06/2012): Fixed 1- [from 2.5.1] substvec slowdown [F25] 2- logfile: strip properly color escape sequences [#1225] [C18] BA 3- ispower(x < 0,, &n): n could have the wrong sign [#1302] [F45] 4- mathnf(..., 4) didn't remove 0 columns from HNF [#1271] [F61] JD 5- possible SEGV in pari_init_opts [#1264] [F62] BA 6- ellorder(E,P*Mod(1,p)) did not work if E was defined over Z [F63] 7- parimacro.tex: pdftex --output-format dvi would produce a PDF [F66] BA 8- pari_close failed to free all allocated memory [#1297] [F67] 9- issquarefree(0) => error [#1304] [F71] 10- sqrt(0.E-97-1.12-97*I) -> div by 0 [#1309] [F76] PH 11- vecsort0 was not valid C code (miscompiled by gcc 4.7) BA 12- FpX_gcd(0,x) -> div by 0 [F77] 13- x; y; p; q; subst(Mod(q,p), q, x + y) --> Mod(1, p)*x [#1321] [F78]
