### New and noteworthy

#### Updated PMD Designer

This PMD release ships a new version of the pmd-designer.
For the changes, see [PMD Designer Changelog](https://github.com/pmd/pmd-designer/releases/tag/6.17.0).
It contains a new feature to edit test cases directly within the designer. Any feedback is highly appreciated.

#### 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)

#### Modified Rules

*   The Java rule {% rule "java/errorprone/CloseResource" %} (`java-errorprone`) ignores now by default
    `java.io.ByteArrayInputStream` and `java.io.CharArrayWriter`. Such streams/writers do not need to be closed.

*   The Java rule {% rule "java/errorprone/MissingStaticMethodInNonInstantiatableClass" %} (`java-errorprone`) has now
    the new property `annotations`.
    When one of the private constructors is annotated with one of the annotations, then the class is not considered
    non-instantiatable anymore and no violation will be reported. By default, Spring's `@Autowired` and
    Java EE's `@Inject` annotations are recognized.
