This incident has been resolved. The root cause has been addressed and the Marketplace team has updated all affected add-ons' compatibility values.
Vendors should once again be able to set their add-on compatibility as expected, and customers will no longer receive erroneous notifications about having incompatible add-ons.

The Marketplace team has identified an issue where add-on compatibility was changed unbeknownst to the add-on vendors.
The impact on vendors is that they need to update their add-on compatibility to include the latest JIRA Server versions, and in some rare cases, are unable to do so.
The impact on customers is that, if running JIRA 7.3, they may erroneously be told that their add-ons are incompatible.
The Marketplace team is currently working on identifying the root cause and resolving the issue.
