JetBrains Blog·low signal

JetBrains published same-day Java 26 support documentation for IntelliJ IDEA, covering AOT cache profiling workflow integration, a new PEM format editor, and the preview feature enablement toggle for structured concurrency and primitive patterns. Day-one IDE support for JDK releases is now the expectation rather than the exception. Developers running Spring Boot, Quarkus, or Micronaut can upgrade to Java 26 without waiting on IDE tooling lag.
