The PMD team is pleased to announce PMD 6.30.0-SNAPSHOT.

This is a minor release.

CPD

• The C# module now supports the new option --ignore-literal-sequences, which can be used to avoid detection of some uninteresting clones. Support for other languages may be added in the future. See #2945

API Changes

Deprecated API

• ASTPackageDeclaration#getPackageNameImage, ASTTypeParameter#getParameterName and the corresponding XPath attributes. In both cases they’re replaced with a new method getName, the attribute is @Name.
• ASTClassOrInterfaceBody#isAnonymousInnerClass, and ASTClassOrInterfaceBody#isEnumChild, refs #905

Internal API

Those APIs are not intended to be used by clients, and will be hidden or removed with PMD 7.0.0. You can identify them with the @InternalApi annotation. You’ll also get a deprecation warning.
