Logi Composer Version 25 Summary Of Changes

This is a summary of the major changes made in version 25 of Composer. It is provided so you can quickly identify new and changed Composer features before upgrading from Composer 24 to Composer 25.

Composer is offered on a quarterly release schedule, and our version numbering system reflects this. The current major release of Composer is v25.2.

Upgrade Considerations

Be sure to back up your metadata store (see Back Up the Metadata Store) before you upgrade.

Upgrading to Logi Composer v23.2 or later includes an upgrade of Java runtime from 11 to 17, installed and configured automatically during upgrade.

Important: Before you upgrade to Composer v25.2 you must use a newer version of CentOS than CentOS 7. If you are not using this tool, you can exclude the sdk-service when installing or upgrading Composer.

Note: New installations of Logi Composer(v24.3 and later) use PostgreSQL 16. If you are upgrading your environment to v24.3 or later, you can retain your existing PostgreSQL version.

To ensure services start properly after upgrade in a Linux environment:

1. Verify all of your JVM setting overrides are defined in the /etc/zoomdata directory (not /opt/zoomdata/conf).

2. The .jvm files in /etc/zoomdata/ only contain parameters that are different from default ones, typically Xms/Xms settings, javaagent settings.

If you have copied the entire .jvm file from /opt/zoomdata/conf for placement into /etc/zoomdata, that configuration is not overwritten after upgrade. Properties such as XX:+UseConcMarkSweepGC can prevent services from starting on Java 17 runtime.

For more information on configuration setups and overrides, see Configure Memory Settings and Connector Properties and Property Files.

Note: If you are upgrading from an earlier version of Logi Composer, this may be a breaking change: the introduction of the system attribute User.timeZone may cause a conflict if you used this as a custom attribute. See Upgrade Workflow.
