+In [1211](https://github.com/palantir/palantir-java-format/pull/1211) we shipped Java 21 support. Since then we've
+kept up with the language and now also support formatting the newer syntax introduced up through Java 26, including

-- the Gradle daemon and the Intellij Project SDK are set to Java 21
+- the Gradle daemon and the Intellij Project SDK are set to Java 26 (or, at minimum, to the JDK version in which the

 - or that the gradle property `palantir.native.formatter=true`. This will run the formatter as a native image, 
 - independent of the Gradle daemon/Intellij project JDK version.
