PCRE is a widely used Unicode-compatible regular expression engine. It implements Perl5 regex syntax and semantics, some Python, .NET and Onigurama extensions. It uses just-in-time compilation, has consistent escaping rules, and allows for recursion, assertions and conditional patterns or complex subroutines and callouts, thus goes far beyond classic regular expressions.
minor bugfix: This release is happening soon after 10.38 because the is important. 1. incorrect detection of alternatives in first character search in JIT. 2. Update to Unicode 14.0.0. 3. Some code cleanups (see ChangeLog).
