Versions and history

Publishing writes a version. The History tab lists them, newest first.

Version history is a Teams feature. Without a Teams-licensed organisation the tab explains that rather than opening. Publishing still snapshots, but the snapshots cannot be browsed or restored.

What a version holds

A complete frozen copy of the blueprint at publish time: tabs, diagram sources, strata and files. It is not a diff, so an old version renders as it did rather than being reconstructed.

Comparing

The panel offers four views of a version:


Snapshot preview	The version rendered faithfully, as it was
Diff	What changed against the previous version
Compare with this version	Pick any earlier version as the baseline instead
Raw JSON	The snapshot itself, when the rendered view is not enough

Diffing against the previous version answers "what did that publish change". Compare with this version sets an older baseline and answers "what has changed since the release we shipped against".

Restoring

Restore replaces the current content. It deletes and recreates the blueprint's tabs, strata and files from the snapshot, and anything you have not published since is gone. Confirming takes two clicks, and the second one says so.

History is append-only, so the state you replaced is itself still a version. A restore you regret is undone by restoring the one before it.

Pinning

An embed can be pinned to a version rather than tracking the latest. A blueprint quoted in a report then stays as it was on the day it was quoted.
