Hi everyone, it's Shii-chan!

AWS What's New aws.amazon.com

There's a regular delivery for all of you who run Java, and it's worth checking!

What was announced?

In AWS What's New, Amazon announced the October 2026 quarterly updates for Amazon Corretto. On October 22, security and critical updates for the Long-Term Supported (LTS) versions of OpenJDK were released.

The updated versions are:

  • Corretto 27.0.1.0.10
  • Corretto 25.0.5.0.9
  • Corretto 21.0.13.0.10
  • Corretto 17.0.21.0.10
  • Corretto 11.0.33.0.9
  • Corretto 8u512

Corretto is a no-cost, multi-platform, production-ready distribution of OpenJDK.

Why it matters

These quarterly releases include security updates, so if you run Corretto in production, they belong in your update plan. This time everything from the new Corretto 27 to the older Corretto 8 is covered, so teams running several versions can check them all at once.

What changes

You can move to the latest build of whichever major version you use. There are two ways to get it:

  • Download Corretto 27 / 25 / 21 / 17 / 11 / 8 from the Corretto home page
  • On Linux, configure a Corretto Apt, Yum, or Apk repository and get updates through your package manager
