pari-2.9.5(STABLE) released |
Dear PARI lovers, I would like to announce the release of pari-2.9.5 (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 2.9.5 (released 18/05/2018): [last column crossreferences current development release 2.10.0] Fixed 1- powuu(0,1) -> SEGV [F123] 2- matsolvemod([;],2,[]~) -> no solution [ instead of []~ ] [F125] 3- a[1]=vector(10):a[1][1]=b;a[1]=vector(10); could leak memory [F126] 4- lcm(Pol(0),0) -> division by 0 [F127] 5- QX_complex_roots(a*x^n,) => SEGV [F128] BA 6- default(strictargs,1); my(a=2);(f(b,c)=123);f(1) => SEGV [#2004] [F129] 7- factor(0.*x + 1) -> SEGV [#2005] [F130] 8- sinh(x close to 0): loss of accuracy [F131] 9- sinc(0.*I) -> division by 0 [F132] 10- nffactor(y^8-y^6+y^4-y^2+1,x^4-1) -> concatenation error [#2009] [F134] 11- memory corruption in nffactor [#2013] [F137] BA 12- partitions(1,[0,5],[3,4]) -> incorrect result [F138] 13- quadclassunit(-699,,[6,6]) -> SEGV [#2015] [F139] 14- polcoeff(t_SER) -> incorrect types and values polcoeff(1/(1+x+y+O(y^2)+O(x^2)), 1,y) -> 2*x-1 [now -1+2*x+O(x^2)] polcoeff(y+O(y^2), 0, x) -> 0 [now y+O(y^2)] [F141] 15- ellperiods([1,0.1 + I/10^50]) -> division by 0 [F142] 16- nfmodpr(nfinit(x),[],[]~) -> SEGV [#2020] [F143] 17- nfisisom(nfinit(x^2+4),x^2+1) -> reverse isomorphism [#2022] [F144] 18- missing GC in lfuntheta [F148] 19- gamma(0.0+1/2*x+O(x^2)) -> domain error in factorial [F150] 20- affrr(0.0, x) did not reset the exponent correctly.
