Compare releases

Open Settings › Model, select a model, Releases, then the release to inspect. See Releases for immutable definitions and permissions.

  1. Find Changes in this release. Read Before and After; After is the open release. The suggested predecessor comes from activation history or the earlier installed release. It is not necessarily the workspace you currently have open.
  2. Use Compare with to choose another baseline. A comparison may cross model families, so check both names and versions rather than assuming they share a lineage.
  3. Read the changes table’s Kind, Path, Before and After. These describe model definitions, not a history of record edits. Inspect removals as well as additions.
  4. No semantic changes means the two documents define the same model. No earlier release means no predecessor is available; select another baseline if offered.
  5. If Comparison unavailable names an unsupported model language, choose another release. Its metadata and Export JSON remain available for specialist inspection. A loading or failed comparison is not an empty comparison.

Release history with baseline selector and semantic before and after changes

The separate activation check under Workspaces running reads each workspace’s data. A small or empty comparison alone does not establish that activation in a chosen workspace is safe.
