The 4.13.1 release has:
- Some minor performance improvements
- An optional build tag -tags antlr.nomutex which allows a build without
using mutexes, when the user knows they will not use it with multiple
go routines. (Note, somewhat experimental)
Note that I did not remove the sort.Slices calls. They will not be experimental for long
and are implemented efficently. Please make a fork if you must use it without this
dependency. Maybe review whether you need to do so for the sake of one call.
