Release Notes
Timepiece version numbers you see in the Release Notes refer to the version numbers given by OBSS. You can find this number at the lower-right corner of the main app page, as shown below.

The version numbers in Jira’s Manage Apps page do not match these numbers. The Manage Apps Page Version Numbers are the Forge UI module version numbers of the app. They are automatically generated by Atlassian Marketplace and follow their own logic. Those version numbers are not referenced in our documents and are only used in occasional update warnings in the UI.
