PMD Release Notes

Edit me

??-????-2020 - 6.28.0-SNAPSHOT

The PMD team is pleased to announce PMD 6.28.0-SNAPSHOT.

This is a minor release.

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 for details.

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