is this enabled by default in 1.30?
If yes, since what version?
My Common.js seems to work without setting $wgUseSiteJs = true;
thx

Just to not leave an (old) question unanswered:
As far as I know/see, it's always been enabled by default. https://www.mediawiki.org/w/index.php?title=Manual:$wgUseSiteJs&oldid=8478
