Is TC Custom JavaScript still maintained?

It has gone over two years without an update, and it has a second warning sign: runs site code.

Quiet: No update for over a year.

Placements are our opinion, based on public evidence. Risk here means a plugin may not get a fix if a problem appears. It doesn’t mean we found a flaw, unless we show an advisory. Going quiet alone never puts a plugin in Replace now.
