Version History
Open a document's version history to see every revision it holds, restore an earlier one as the current version, insert or reorder versions, and rename, download, delete, or suppress an individual version.
Overview
Each time a document's content is replaced, the previous content stays behind as an earlier version, so the document number and its metadata survive across revisions.
Select Version History from a document's Options menu, opened by selecting the three dots at the end of its row. The page is headed Version history and explains that restoring a previous version makes it current while leaving the versions in between alone. Select Back to documents to return to the list you came from.
The Version List
Three view modes present the history as a list, as cards, or as a table. Choose whichever suits how many versions you are comparing.
To see what changed between two versions, select the box beside each of them and choose Compare Documents, covered in Comparing Documents.
Versions are listed newest first. Each entry carries a preview thumbnail, the file name, and a highlighted Version Index such as "Version Index - 1.0", followed by the document title, when it was last modified and by whom, the revision badge such as v B, and the file size. A Current Major version badge marks the version in use, so the entries without it are the superseded ones.

Working With a Single Version
The Options menu at the end of a version's row acts on that version alone. What it offers depends on your access rights and on the state of the version you opened it on, so a version that is already current, or one that has been deleted, shows a different set.
| Action | What it does |
|---|---|
| Make current | Restores this version as the document's current one. It is not offered on a version that is already current, deleted, or suppressed. |
| Rename | Changes the name recorded against this version. |
| Download | Downloads this version's original file. |
| Export PDF | Produces a PDF of this version. |
| Attach Rendition | Attaches a viewable copy, such as a PDF of a drawing, to this version. |
| Publish | Publishes this version. It is offered only where publishing is available. |
| Suppress | Hides this version from users who have not been allowed to see suppressed versions, covered in Suppressing a Version. |
| Unsuppress | Makes a suppressed version visible again. It appears only on a suppressed version. |
| Delete | Removes this version. |
| Undelete | Restores a version you deleted earlier, and appears only on a deleted version. |
These actions are not offered to everyone. If you cannot restore versions, the menu does not open at all, unless you can see suppressed versions, in which case it opens carrying the suppression actions alone.

Suppressing a Version
Suppressing hides a version from the history without deleting it, which suits a revision that was issued in error and should not be part of the record people read.
The Suppress Revision dialog hides the revision from users who have not been allowed to see suppressed versions. For those users, suppressed versions do not appear in the history at all.
Suppress is offered only on a version that is superseded, so you cannot suppress the version currently in use, one already suppressed, or one that has been deleted. Unsuppress appears in its place on a suppressed version.
Inserting and Reordering Versions
Two controls at the top of the page change the content and order of the history. Neither appears unless you have been allowed to insert revisions.
Insert Version opens the Insert Revision dialog, which places a version at an index you choose rather than on the end. Enter the major and minor revision index the inserted version should take, then select Submit.
Reorder Versions opens the Reorder Versions dialog, where you move a version to a different position in the history. Choose the version to move by its index, choose before or after, choose the version it should sit beside, then select Submit.
Inserting, reordering, deleting, and suppressing all change a document's record. Use Make current where you only need an earlier version back in use, since it leaves the history intact.
Document Actions
Act on documents through Lunr's two menus, the Options menu at the end of a document's row for that document alone and the grouped More menu in the Action Pane for everything you have selected, and share links to a document or its latest version.
