Jira hosting: Cloud
We got some similar questions from some of our users like “Why the installation shows version 2.1.6-AC (1) whereas the scheduler page says The Scheduler v2.7.3?" (2).
Thank you for bringing this to our attention! But answer is very simple. Difference is caused by cloud app versioning by marketplace. Version number 2.1.6-AC is generated by Atlassian, even big changes in the app can receive small version updates. While we would like to keep things organized with 2nd number referring to bigger releases and in sync with our app development planning, so we have a bit different versioning.
This affects only Jira Administrators, because rest of the users don’t see information about marketplace version number (even on marketplace).
