Releases
Version lines your licenses can target and that the update checker can use.
Software releases tie licenses to a specific build or channel and power license-aware updates in the dashboard and from /api/Updates/... for the SDK.
Dashboard
Manage releases under each product and via global Releases routes. When creating a license, you select a softwareReleaseId so validation and update checks can reason about compatibility.
API
Release lines, metadata, and attachments are exposed alongside product routes (see catalog topic). Pair with storage connectors if binaries live on Drive/OneDrive/custom servers.
