Can log debug messages to error log instead of DB by setting constant DEBUG_TYPE to "warn".
Can have an <o2 if> inside an <o2 setVar> even if you want to assign a non-stringified value (like an object) to the new variable.
Bug fix: Keep the double colons.
Things should work even if v-parameter (version) is missing.
Better debug message.
Discard query string parameters in currentUrl for ajax requests.
Make sure default value is inserted in database instead of null.
Avoid bootstrap conflict.
