Eclipse Temurin has achieved a remarkable milestone: 700 million cumulative downloads! This achievement is a testament to the community's trust and the increasing popularity of open source Java, which has seen downloads grow exponentially over the last three years.

The Adoptium Summit, a free half-day virtual event happening on 1 October 2025, will bring together developers, users, and ecosystem stakeholders from around the world to explore the latest innovations in Java and showcase practical real-world use cases powered by Adoptium technologies.

The Eclipse Migration Toolkit for Java (EMT4J) is an open source project under the Eclipse Adoptium Working Group, specifically designed to simplify the process of migrating Java version.

The article introduces Canonical's new builds of OpenJDK, offering enterprise-grade security, extended support, and timely access to new Java releases. A key highlight is the rigorous testing process: Canonical's OpenJDK builds are rigorously tested against the Technology Compatibility Kit (TCK) using the Eclipse AQAvit by Adoptium testing framework to ensure their correctness across various architectures and Ubuntu LTS versions. 

We’re looking to hear from both project developers and contributors eager to share their journey and evolution, and from project users who can speak to how they’re applying these tools in real-world use cases. Submit your talk for the Adoptium Summit and inspire a global Java audience.

We have launched the Eclipse Temurin Sustainer Program, inviting enterprises to invest in the long-term sustainability of Eclipse Temurin and other Adoptium projects.
