Release justification: bug fix. Release note (bug fix): CockroachDB could previously crash when evaluating queries with window functions with GROUPS mode of framing when OFFSET FOLLOWING boundary was used and when the offset was a very large value such that it could result in an integer overflow. This is now fixed.
