# CHANGES to the 'primgrp' GAP package

- Add `PrimitiveGroupsAvailable` to the manual (it has been around
for a long time but we forget to link it up there)

if the extra data set is not installed
## 4.0.0 (2024-12-06)
- Add support the primitive groups of degree 4096 to 8191; these
must be downloaded separately, see README.md for details
- Add Jesse Lansdown as package author
- Stop using `InstallValue`
## 3.4.3 (2022-12-10)
- Fix inconsistencies in `COHORTS_PRIMITIVE_GROUPS` in degrees 1550 and 1575

- Ship data files compressed to save disk space
- Update some links
- Minor janitorial changes
## 3.4.2 (2022-05-03)
- Unify notation for names that involve Mathieu groups to use
M(n), instead of a mix of M(n) and M_n

- Fix the names of PrimitiveGroup(i,j) for (i,j) in
{ (100,14), (121,38), (289,35) }
- Rename PrimitiveGroup(960,7) from OPlus(8, 2) to O+(8, 2)
to be consistent with all other groups related to O+ or O-
