+### Added
+- A complete, but as of yet **unverified** classification of the groups of
+  class numbers 15 to 20 (by T. Breuer) can now be loaded using
+  `LoadUnverifiedSmallClassNrGroups()` (which replaces the old command
+  `LoadIncompleteSmallClassNrGroups()`).

+### Changed
+- `IdClassNr` is now even faster for most groups, and no longer relies on
+  `IdGroup` / `SmallGrp`.
+- Now requires GAP version >= 4.15.
+- Updated installation instructions.
+- Janitorial changes.
