Wren:IG 5.0.0 Released

September 25, 2025

We are excited to announce that the brand new release of Wren:IG 5.0.0 is finally out! This is the first release of Wren:IG that is fully independent of the legacy infrastructure. Its technological stack has been updated to be compatible with JDK 21, and all changes have been carefully curated to provide a high level of security while still offering a reliable migration path from legacy OpenIG installations.

If you are already running Wren:IG or an unsupported version of OpenIG, we strongly recommend that you upgrade, as only the new versions will receive the support they deserve.

List of significant changes:

• Add Java 21 support and drop Java 8 support
• Change Maven groupId to org.wrensecurity.wrenig
• Upgrade to the newest wrensec-parent and wrensec-commons
