[GAP Forum] GAP 4.9.3 release announcement

[Alexander Konovalov]

Dear GAP Forum,

The next minor release of GAP, version 4.9.3, is now available at

	http://www.gap-system.org/Releases/

An overview of changes introduced in GAP 4.9.3 is given below.

* Fixed a regression in HighestWeightModule caused by changes in 
sort functions introduced in GAP 4.9 release, which in certain
cases lead to a break loop (#2491).

* Fixed a compile time assertion that caused compiler error on
some systems (#2691).

In addition, GAP 4.9.3 distribution contains contains updated
versions of some packages from GAP 4.9.2 distribution, and
three new packages:

* The curlInterface package by Christopher Jefferson and Michael
Torpey, which provides a simple wrapper around libcurl library
(https://curl.haxx.se/) to allow downloading files over http,
ftp and https protocols.

* The datastructures package by Markus Pfeiffer, Max Horn, 
Christopher Jefferson and Steve Linton, which aims at providing
standard datastructures, consolidating existing code and
improving on it, in particular in view of HPC-GAP.

* The DeepThought package by Nina Wagner and Max Horn, which
provides functionality for computations in finitely generated
nilpotent groups given by a suitable presentation using Deep
Thought polynomials.

The full list of new and updated packages in GAP 4.9.3 
distribution is:
