As of July 1st (and the official end of Universal Analytics) CAOS will no actively support extensions.
All action and filter hooks will remain in place (some might change names), so any extensions you developed yourself should remain functional or will require minor tweaks.
The only officially supported extension will be CAOS Pro, which’ll have its own tab: Avoid Ad Blockers (Pro). The Extensions tab will be removed, but can be added back by using the caos_settings_tab filter.
