Version history and comparing versions

Each lesson keeps its own history. Open it with the clock button at the bottom right of the lesson editor (Version history; not shown on phones). The Version History panel lists versions newest first, named or marked Auto-save, each with Compare and Restore.

• A version is saved automatically when you open a lesson whose latest version is more than 30 minutes old, and before every restore.
• Up to 20 versions are kept per lesson; the oldest go first.

Restore replaces all of the lesson's current blocks with the version you chose, after you confirm. The lesson as it stood is saved as a version first, so you can restore back to it.

A Scenes course is versioned as a whole. Open Tools → Version history (or ⌘K → Version history).

• Save Snapshot: give it a name (and a description if you like) and click Save Now before a big change.
• An automatic snapshot is taken every five minutes while you work, labeled Autosave with the time.
• Each snapshot shows whether it was Auto, Manual or Before restore, and how many slides and objects it holds, with Compare, Restore and Delete snapshot. Click a manual snapshot's name to rename it.

Restore replaces the whole course with the snapshot. The course as it stands is saved first, so you can come straight back; the editor then reloads. Up to 50 snapshots are kept; at the limit, delete older ones to save new manual snapshots.

Export → Compare versions in the course editor (or Compare next to any version) opens a comparison of two versions of the course: what a learner would see differently, with every change to a question — answer keys, options, points — called out first.

Choose From (older) and To (newer). Either can be the Current draft, any publication (every time the course was published), a Scenes snapshot, or a lesson version; the swap button reverses them. The usual question — what changed since the last publish? — is the latest publication against the current draft.

When the newer side is a publication or the current draft, Evidence pack (printable) and Evidence pack (JSON) export the comparison as a record you can hand to an auditor or a regulator. The evidence pack is part of the Enterprise plan.

Version history and restore are on every plan. Comparing versions needs a plan (the trial included); the evidence pack is Enterprise. See Plans and limits.
