Dear GAP Forum,
This is to announce the release of GAP 4.6.5.
You can download GAP 4.6.5 from
http://www.gap-system.org/Releases/
The alternative GAP distributions listed at
http://www.gap-system.org/Download/#alternatives
will be updated in due course.
The overview of changes in GAP 4.6.5 is given below.
Improved functionality:
* TraceMethods and UntraceMethods now better check their arguments
and provide a sensible error message if being called without
arguments. Also, both variants of calling them are now documented.
* Library methods for Sortex are now replaced by faster ones using
the kernel SortParallel functionality instead of making expensive
zipped lists.
Fixed bugs which could lead to incorrect results:
* IntHexString wrongly produced a large integer when there were too
many leading zeros. [Reported by Joe Bohanon]
Fixed bugs that could lead to break loops:
* A bug that may occur in some cases while calling
TransitiveIdentification. [Reported by Izumi Miyamoto]
* The new code for semidirect products of permutation groups,
introduced in GAP 4.6, had a bug which was causing problems for
Projection. [Reported by Graham Ellis]
In addition to the improved functionality and fixed bugs in the
core GAP system, the following packages have been updated since
the previous GAP 4.6.4 release: AutoDoc, CRISP, EDIM, Float,
HAP, hecke, IRREDSOL, Modules, NumericalSgps and Smallsemi.
We encourage all users to upgrade to GAP 4.6.5. If you need any
help or would like to report any problems, please do not hesitate
to contact us at support at gap-system.org.
Please note that we regularly update the GAP distribution to include
new versions of GAP packages, but we may not announce each of them
to the Forum. We intend to use the Forum to announce updates of the
core GAP system and only of some packages which may fix serious
issues or have major influence on GAP.
Wishing you fun and success using GAP,
The GAP Group
