Library versioning has been introduced and improved over the past couple of versions. We recently enabled the functionality and I wanted to implement a monitoring on version saves in general through the Action Logging and found this article: https://community.spotfire.com/articles/spotfire/managing-library-versions-in-spotfire/
What we now can query is delete_ver and restore_ver. It will not show if a Spotfire analysis has been saved as new version only if the user would have chosen to save_copy_ver through the web UI which likely no user will ever do.
Please add save_ver for analysis that were saved as new version and save for new analysis which is the current state for the creation and repetetive saving in the Action Logs.
