### New and noteworthy

#### CPD's AnyTokenizer has been improved

The AnyTokenizer is used for languages, that don't have an own lexer/grammar based tokenizer.
AnyTokenizer now handles string literals and end-of-line comments. Fortran, Perl and Ruby have
been updated to use AnyTokenizer instead of their old custom tokenizer based on AbstractTokenizer.
See [#2758](https://github.com/pmd/pmd/pull/2758) for details.

AbstractTokenizer and the custom tokenizers of Fortran, Perl and Ruby are deprecated now.
