From the Preface of GAP 3.4.4

Welcome to the first release of GAP from St Andrews. In the two years since the release of GAP 3.4.3, most of the efforts of the GAP team in Aachen have been devoted to the forth-coming major release, GAP 4.1, which will feature a re-engineered kernel with many extra facilities, a completely new scheme for structuring the library, many new and enhanced algorithms and algorithms for new structures such as algebras and semigroups.

While this was going on, however, our users were not idle, and a number of bugs and blemishes in the system were found, while a substantial number of new or improved share packages have been submitted and accepted. Once it was decided that the computational algebra group at St Andrews would take over GAP development, we agreed, as a learning exercise, to release a new upgrade of GAP 3.4, incorporating the bug fixes and new packages.

Assembling the release has indeed been a learning experience, and has, of course, taken much longer than we hoped. The release incorporates fixes to all known bugs in the library and kernel. In addition, there are two large new data libraries: of transitivie permutation groups up to degree 23; and of all groups of order up to 1000, except those of order 512 or 768 and some others have been extended. This release includes a number of share packages that are new since 3.4.3:

for computing the automorphism groups of soluble groups;
for computing with finite Coxteter groups, Hecke algebras, Chevalley groups and related structures, replacing 'weyl';
for computing with crystallographic groups;
for comnputing with near-rings and semigroups;
for computing with rational and integer matrix groups;
linking to Knuth-Bendix package for monoids and groups;
for analysing matrix groups over finite fields, replacing 'smash' and 'classic';
linking to a polycyclic quotient program;
for computing the representation theory of the symmetric group and related structures; and
for computing with crossed modules.

A number of other share packages have also been updated. Full details of all of these can be found in the updated manual, which is now also supplied in an HTML version.

Despite the tribulations of this release, we are looking forward to taking over a central role in GAP development in the future, and to working with the users and contributors who are so essential a part of making GAP what it is.
