The Selectacular and Trim Comments add-ons were added as dependencies of ThemeBuilder to solve specific developer issues at the time. These issues are no longer relevant and so we removed these add-ons as dependencies in ThemeBuilder from version 5.6.0.
The decision to remove Selectacular is particularly related to issues with Confluence 6 onward:
If you see any of these problems in Confluence 6+ please go to your manage add-ons page in Confluence Administration and disable Adaptavist Selectacular. You can also uninstall the add-on if you prefer.
If you're going to miss the functionality from Trim Comments you can find it in our ScriptRunner for Confluence add-on, which brings you the power to extend Confluence events, script macros or customise menus and dialogs.
