### New and noteworthy

#### Lua support

Thanks to the contribution from [Maikel Steneker](https://github.com/maikelsteneker), and built on top of the ongoing efforts to fully support Antlr-based languages,
PMD now has CPD support for [Lua](https://www.lua.org/).

Being based on a proper Antlr grammar, CPD can:
*   ignore comments
*   honor [comment-based suppressions](pmd_userdocs_cpd.html#suppression)
