From ~2001 to 2020, there were lots of version upgrades in the supported programs. Fortunately, now gathering all the data is easier due the new Dockerized regex tester (see #6).
Some programs have changed fundamentally:
JavaScript: now using Node.js instead of Netscape
lex: now using GNU flex
PHP: switch from old ereg to preg (PCRE)
Some programs added support for new metacharacters or new features in the regexes. Some notable changes:
{} quantifier is supported
Escaping with \\ to avoid gotchas
Updated literal chars escapes
\ must be escaped inside []
POSIX is supported
[\t] works
Please see the individual commit messages for details.
