Oracle releases Java updates for multiple versions

Oracle has released new Java Virtual Machine (JVM) updates on October 20, 2026. These updates cover several versions, including the newest short-term release, Java 27, and long-term support (LTS) releases for Java 25, 21, 17, 11, and 8.

Specific version updates include 27.0.1, 25.0.5, 21.0.13, 17.0.21, 11.0.33, and 1.8.0_511. While these are categorized as critical patch updates, they follow a quarterly schedule. The updates appear to be modest in terms of compatibility, with no immediate breaking changes reported in the release notes.

In the context of upgrading between LTS versions, such as moving from Java 21 to Java 25, developers should be aware of removals of previously deprecated features. For instance, starting with JDK 23, annotation processors no longer run by default unless explicitly configured via specific flags like -processor or --processor-path.
