# 2019

DNAnexus publishes release notes by deployment date. Most platform releases are deployed on Tuesdays throughout the year, which provides a predictable cadence for delivering security updates, reliability improvements, and new platform capabilities.

{% hint style="info" %}
**Product Versioning**: Release versions are identified by deployment date. For example, a release deployed on June 17, 2025 can be identified as `_20250617` in validation and compliance records. This format helps regulated customers identify exact production release versions for compliance.
