7 Changes between GAP 4.3 and GAP 4.4

This chapter contains an overview of most important changes introduced in GAP 4.4. It also contains information about subsequent update releases of GAP 4.4.

7.1 Changes in the core GAP system introduced in GAP 4.4

7.1-1 Potentially Incompatible Changes

These changes are, in some respects, departures from our policy of maintaining upward compatibility of documented functions between releases. In the first case, we felt that the old behavior was sufficiently inconsistent, illogical, and impossible to document that we had no alternative but to change it. In the case of the package interface, the change was necessary to introduce new functionality. The planned and phased removal of a few unnecessary functions or synonyms is needed to avoid becoming buried in "legacy" interfaces, but we remain committed to our policy of maintaining upward compatibility whenever sensibly possible.

7.1-2 New Packages

The following new Packages have been accepted.

7.1-3 Performance Enhancements

The improvements listed in this Section have been implemented by T. Breuer and A. Hulpke.

7.1-4 New Programming and User Features

Finally, as always, a number of bugs have been fixed. This release thus incorporates the contents of all the bug fixes which were released for GAP 4.3. It also fixes a number of bugs discovered since the last bug fix.

Below we list changes in the main system (excluding packages) that have been corrected or added in bugfixes and updates for GAP 4.4.
