As always, all binaries are thoroughly tested and available free of charge without usage restrictions on a wide range of platforms. Binaries, installers, and source code are available from the Temurin download page, official container images are available at DockerHub, and installable packages are available for various operating systems.
Fixes and Updates
This release contains the following fixes and updates.
New and Noteworthy
Windows aarch64 Not Included for JDK 25 and JDK 26
Eclipse Temurin does not currently ship Windows aarch64 binaries for JDK 25 or JDK 26. Work to deliver these builds is ongoing; users who require Windows aarch64 support for those versions should watch the Adoptium blog for announcements when availability changes.
Ubuntu 26.04 LTS Package Support
Native installable packages (.deb) for Ubuntu 26.04 LTS (Resolute Ringtail) are now available for all supported JDK versions (8, 11, 17, 21, 25, 26). Ubuntu 26.04 packages can be installed through the Adoptium package repositories in the usual way. Users running Ubuntu 24.04 (Noble Numbat) or earlier are unaffected; their packages continue to be provided as before.
Updated CA Certificates
The CA certificate bundle bundled with Eclipse Temurin has been refreshed to incorporate the latest Mozilla root-certificate updates. This ensures that TLS connections made with the built-in cacerts truststore remain valid against current certificate authorities without requiring any manual intervention.
Reproducible Build Improvements
Several improvements have been made to the reproducible-build verification tooling in this release cycle:
- Windows aarch64 cross-compiled targets are now handled by
windows_repro_build_compare.sh, extending reproducibility verification to that platform combination. - The Linux and macOS
repro_build_compare.shscript now correctly clones the upstream OpenJDK GA tag, fixing a regression that caused incorrect source checkouts in comparison runs. - Pandoc version validation in the SBOM reproducibility check for JDK 25+ has been tightened, allowing the check to pass with a broader range of compatible Pandoc versions while still enforcing correctness.
Build Reliability: Boot JDK Download Retry Logic
The build tooling now retries failed curl commands when downloading the boot JDK. This reduces transient build failures caused by temporary network issues in CI environments, improving overall release reliability.
