New Features:
- The operator # now works for associative arrays (returning
the number of keys).
Changes and Removals:
- The speed of RandomSubset has been improved for large sets.
Bug Fixes:
- The functions And, Or, Xor, and Not no
longer crash when one of the arguments is the null sequence.
- A bug has been fixed which could cause hashing of multisets to return
invalid values for certain underlying types such as vectors.
- A bug in associative arrays that could cause crashes when keys of
different universes are used has been fixed.
- A memory leak which occurred when records are created has been fixed.
