Every time you publish a model, or save a change to its draft, Tekst records a version. The version history shows what changed and when, lets you open an earlier version to read it, and lets you bring any earlier version back as a new draft.
This article covers the history sheet and older versions. To publish the draft you are working on, see the "Publish a model draft" article.
Open the version history
- Open the model.
- Select the overflow menu (the three dots) in the top right of the model header.
- Select History. The model's settings open on the History tab.
Read the timeline
Versions are listed newest first, each with the changes made in it.
Two badges tell you where you are:
- Draft marks your current unpublished working copy.
- Live marks the version that is processing messages right now.
The connector down the left tells the same story: a solid line runs through the published versions, a dotted line through the unpublished ones.
Under each version are its changes, one card per change, described against the version before it. The very first version has nothing to compare against, so it shows no cards, and neither does any other version with nothing to report.
Open an earlier version
Hover a version in the list and two controls appear next to its timestamp.
Select the eye icon to open that version. The page switches to that version's labels or entities, and the badge next to the model name changes to Older version (vN).
A bar at the bottom of the page reminds you what you are looking at.
While an older version is open the model is read-only: you cannot edit it, publish it, or discard your draft. The accuracy figure shows a dash (-), because accuracy is not stored for past versions. Opening the version that is currently live shows Live version (vN) instead, and the bar says you are viewing the published model.
The address of the page includes the version you are viewing, so you can reload or share the link and land back on the same version.
Select Back to draft (or Back to published model on a model with no draft) to return. Nothing changes: viewing a version never affects what is running.
Bring an earlier version back
Use as draft copies the version you are looking at into a new draft. It does not publish anything: the published model keeps running until you publish the new draft yourself.
You can do this in two places:
- From the footer bar while viewing the version.
- Straight from the history list, using the arrow icon next to a version's timestamp. You do not have to open the version first.
Once the copy is made, the page returns to the editable draft with that version's configuration in it, ready for you to adjust and publish.
Two cases where Use as draft is unavailable:
- On the version that is currently live, because it is already the published version.
- While an improvement run is in progress. Wait for it to finish or cancel it.
If you had a draft going, copying an older version replaces it.
Undo
There is no undo shortcut inside a model. Pressing Cmd+Z (or Ctrl+Z) outside a text field tells you so and offers View history, which opens this panel. The history is the undo: find the version you want and use it as a draft.
