JEP 532, Primitive Types in Patterns, instanceof, and switch (Fifth Preview), has been elevated from its JEP Draft 8379318 to Candidate status. This JEP proposes a fifth preview, without change, after four rounds of preview delivered in JDK 23 through JDK 26. This feature enhances pattern matching by allowing primitive types in all pattern contexts, and extending the instanceof and switch constructs to work with all primitive types.
