Wiki (Confluence) 5.9 to 5.10 upgrade notes
Confluence 5.10.8 changes
We are aware of only one macro that became incompatible with the change from version 5.9.14 to version 5.10.8, the imagemap macro. The ImageMap plugin/macro is now disabled as there is no free update for compatibility.
For detailed upgrade changes, please check the Confluence Release Notes for version 5.10. For instance, note that space administrators now have more control over the left-hand sidebar.
