Feb 20, 2022: 3.2.0 new %option ctorinit; faster compilation of regular expressions to tables and direct code DFAs; refactored SIMD source code to enable AVX2 and AVX512BW optimizations in multi-version matcher code; updated Windows binary file opening.
Feb 23, 2022: 3.2.1 regression bug in 3.2.0 fix.
Mar 13, 2022: 3.2.2 minor improvements.
Apr 2, 2022: 3.2.3 fixed C++17 compliance and dso build.
Apr 29, 2022: 3.2.4 new %begin directive; new --batch=SIZE option argument.
Apr 30, 2022: 3.2.5 minor correction.
May 6, 2022: 3.2.6 improved fuzzy matcher.
May 10, 2022: 3.2.7 improved fuzzy matcher, see also https://github.com/Genivia/FuzzyMatcher.

Aug 29, 2022: 3.2.11 new lua2lisp transpiler example with Bison complete symbols and locations.
Jan 6, 2023: 3.2.12 regression bug fix in trailing context pattern matching, e.g. xy and x/x patterns collided when they should not; updated yaml parser example.
Jan 24, 2023: 3.3.0 overall update; corrected a problem with Unicode characters in regex patterns adjacent to curly braces; permit cxx extension in FSM filename output.
Mar 6, 2023: 3.3.1 for consistency include NAME in default header file name, tables file name, and graphs file name when option --prefix is specified.
Mar 17, 2023: 3.3.2 fix a performance issue with case-insensitive pattern construction.
May 28, 2023: 3.3.3 fix yyrestart dropping the first character; faster Matcher::find().
May 31, 2023: 3.3.4 fix Matcher::find() initialization issue in 3.3.3.

Sep 25, 2023: 3.4.1 make word boundaries \b, \B, \< and \> applicable anywhere in a pattern.
Oct 7, 2023: 3.5.0 updated to Unicode 15.1; clarify . (dot) with %unicode enabled, which is a catch-all pattern; update \X to match only valid Unicode characters.
Nov 5, 2023: 3.5.1 minor improvements.
Feb 17, 2024: 4.0.0 faster Matcher::find() with a new DFA cut algorithm to optimize match prediction speed and accuracy, see also ugrep 5.0; apply Unicode pattern canonicalization with reflex::convert(..., reflex::convert_flag::unicode).
