Dear GAP Forum,
This is to announce the release of GAP 4.8.8, which can be downloaded from
http://www.gap-system.org/Releases/
The changes in the core GAP system introduced in GAP 4.8.8 are:
* Fixed bug in RepresentativeAction producing incorrect answers for both
symmetric and alternating groups, with both OnTuples and OnSets, by
producing elements outside the group. [Reported by Mun See Chang]
* Fixed bug in RepresentativeAction for S_n and A_n acting
on non-standard domains.
* Fixed a problem with checking the path to a file when using the default
browser as a help viewer on Windows. [Reported by Jack Saunders]
For the corresponding changes in the GAP source code, see the GAP 4.8.8
milestone on GitHub:
https://github.com/gap-system/gap/milestone/15?closed=1
Additionally, GAP 4.8.8 distribution contains updated versions
of 29 GAP packages:

Furthermore, the Gpd package by Chris Wensley has been renamed to
Groupoids.
We encourage all users to upgrade to GAP 4.8.8.
Just in case, a common pitfall during GAP installation on Linux and macOS
is to compile only the GAP kernel, but not the packages. This procedure
had changed less than a year ago (in GAP 4.8.4), so let me remind you that
after running
./configure
make
in the GAP root directory you need to change to the 'pkg' subdirectory
and call
../bin/BuildPackages.sh
to run the script which will build most of the packages that require
compilation (provided sufficiently many libraries, headers and tools
are available).
If you need any help or would like to report any problems, please do
not hesitate to contact us at supp...@gap-system.org, or submit new
issues on GitHub:
https://github.com/gap-system/gap/issues
There is also a 'gap' tag for questions about GAP at the
Mathematics Q&A site:
http://math.stackexchange.com/tags/gap/info
In addition, you may find some GAP related news on Twitter:

(you may also read the GAP Twitter feed at http://www.gap-system.org).
Wishing you fun and success using GAP,
Alexander Konovalov
