Dear GAP Forum,
This is to announce the release of GAP 4.7.6, which could be downloaded from http://www.gap-system.org/Releases/ One of the new features is that Windows users may now use the standard installer http://www.gap-system.org/pub/gap/gap47/exe/gap4r7p6_2014_11_15-20_02.exe which became an official format for the GAP distribution for Windows. Alternative installers for Linux and OS X (BOB and GAP Rsync) will be updated later in due course. The overview of changes in GAP 4.7.6 versus GAP 4.7.5 is given below. Fixed bugs which could lead to incorrect results: * A bug that may cause ShortestVectors to return an incomplete list. [Reported by Florian Beye] * A bug that may lead to incorrect results and infinite loops when GAP is compiled without GMP support using gcc 4.9. * A bug that may cause OrthogonalEmbeddings to return an incomplete result. [Reported by Benjamin Sambale] Fixed bugs that could lead to break loops: * ClosureGroup should be used instead of in case there is no parent group, otherwise some calculations such as e.g. NormalSubgroups may fail. [Reported by Dmitrii Pasechnik] * Fixed a line in the code that used a hard-coded identity permutation, not a generic identity element of a group. [Reported by Toshio Sumi] * Fixed a problem in the new code for calculating maximal subgroups that caused a break loop for some groups from the transitive groups library. [Reported by Petr Savicky] * Fixed a problem in ClosureSubgroup not accepting some groups without Parent. [Reported by Inneke van Gelder] Other fixed bugs: * Eliminated a number of compiler warnings detected with some newer versions of C compilers. * Some minor bugs in the transformation and partial permutation code and documentation were resolved. In addition to the improved functionality and fixed bugs in the core GAP system, GAP 4.7.6 includes 25 updates of GAP packages: Package name | Version | Date ------------------------------------------------ AutoDoc | 2014.08.21 | 21/08/2014 Browse | 1.8.6 | 15/08/2014 Congruence | 1.1.1 | 28/10/2014 cvec | 2.5.3 | 08/11/2014 Example | 3.4.5 | 28/10/2014 Float | 0.6.2 | 29/08/2014 genss | 1.6.2 | 24/09/2014 GradedModules | 2014.09.17 | 17/09/2014 GradedRingForHomalg | 2014.08.27 | 27/08/2014 homalg | 2014.09.14 | 14/09/2014 IO | 4.4.4 | 10/11/2014 LAGUNA | 3.7.0 | 11/11/2014 LiePRing | 1.6 | 08/11/2013 LocalizeRingForHomalg | 2014.08.27 | 27/08/2014 MatricesForHomalg | 2014.08.26 | 26/08/2014 ModIsom | 2.3.2 | 04/07/2014 Modules | 2014.07.02 | 02/07/2014 orb | 4.7.3 | 08/11/2014 RCWA | 3.7.0 | 21/07/2014 recog | 1.2.3 | 24/09/2014 recogbase | 1.2.3 | 24/09/2014 ResClasses | 3.4.0 | 21/07/2014 Semigroups | 2.1.1 | 09/09/2014 UnitLib | 3.2.0 | 11/11/2014 Wedderga | 4.7.1 | 07/11/2014 ================================================ We encourage all users to upgrade to GAP 4.7.6.
