This release of PMD brings support for Java 18. There are no new standard language features. Note: Support for Java 16 preview language features has been removed.
Better XML XPath support
The new rule class DomXPathRuleis intended to replace XPathRulethe use of XML rules. This rule executes XPath queries in a different way, which means that expressions are interpreted in PMD the same way they are in all other XPath development tools.

New XPath function
The new XPath functions pmd:startLine, pmd:endLine, pmd:startColumnand pmd:endColumnare now available in XPath rules in all languages. They replace node attributes @BeginLine, @EndLineetc. These properties will be deprecated in a future release.
