pari-2.1.1 released |
Dear PARI lover, this message is to announce the release of version 2.1.1 of the PARI/GP system. The new release can be downloaded from ftp://megrez.math.u-bordeaux.fr/pub/pari/pari.tgz DOS/Windows binaries will be available shortly. This is a BUGFIX release for the stable version 2.1.0 and corrects a number of minor annoyances [configuration problems, compiler bugs, various errors] as well as the following major bugs [session killer, wrong results]: 1) when setting the 'lines' default to a non-zero value, any error (such as ^C) could upset the output driver, eventually wrecking the GP session. 2) nfgaloisconj() could give bogus results due to precision problems 3) when factoring (very) large polynomials over Q[X] using a variant of van Hoeij's algorithm, some factors could be silently forgotten Have fun, The PARI group. P.S: The complete Changelog: Done for version 2.1.1 (released 30/04/2001): [last columns crossreferences the current development release 2.2] Fixed 1- return() could forget objects on heap [F2] 2- polhensellift(x^3+x^2+2,[x^2,x+1],2) --> pols not coprime [F3] 3- Configure missed some shared libraries [e.g RedHat 7.0] [F4] 4- requests for precision of bnfinit(x) [ = Q ] could yield SEGV [F6] 5- compatible = 3 not taken into account when reading a file [F7] 6- lines > 0: output driver didn't reset properly after user output [F9] 7- nfdisc(x^5+2*x^4+3*x^3-3*x^2+122*x-1) --> impossible inverse [F10] 8- bug in gcc-2.95: SEGV on Linux (quicksqri) [F11] 9- addrfrac: could return a t_RFRAC whose denominator wasn't a t_POL[F12] 10- bnfcertify (zimmertbound): off by two error when reading bound [F13] BA 11- pbs in Fp_factor_irred (factoring over Fq a pol. defined over Fp)[F25] 12- typo in quadhilbertimag (SEGV for very large discriminants) [F28] BA 13- isprime(n < 2, 2 or 3) gave wrong result [F31] BA 14- nfgaloisconj(polcyclo(11)+1)--> oo loop [F35] nfgaloisconj(polcyclo(40))-->incorrect result IS 15- typo in squfof tuning on 64bit machines [F36] 16- van Hoeij's algorithm (factor(Z[X])): wrong bound in LLL_cmbf [F41] 17- rare SEGV in nfdisc [F44] 18- rare problem in isprincipal (large non Galois base field) [F56] --> wrong result (generators not required) or infinite loop. 19- build failed with readline-4.2 [F57] Changed 1- DOS distribution archives (GPM removed) [C1] XR 2- try more prime ideals in nfsqff [nffactor, modular part] [C4] 3- renamed library function gsize() to sizedigit() [pb with gtk] [C10] IK 4- let lisGEN() return NULL when EOF is met (was oo loop) [C12] 5- install the whole distribution (see ?12) + improved Configure [C17] Added 1- README.WIN, config/[arch-osname|locatesymbol], doc/tex2mail.1 [A1]
