OpenJDK
JEP 430, String Templates (Preview), has been promoted from Candidate to Proposed to Target status for JDK 21. This preview JEP, under the auspices of Project Amber, proposes to enhance the Java programming language with string templates, string literals containing embedded expressions, that are interpreted at runtime where the embedded expressions are evaluated and verified. The review is expected to conclude on April 13, 2023.
Gavin Bierman, consulting member of technical staff at Oracle, has published the first draft of the joint specification change document for JEP 440, Record Patterns, and JEP 441, Pattern Matching for switch, for review by the Java community.
