Scriptability has been a thing since 2.2.0, released on 2025-06-16, but the built-in script appeared in 3.0 (2025-11-14).

Around here. In the default configuration, it is using the built-in handler. The script can be replaced with something like Nam-Shub of Enki (used by pretty much everything I host, and by Codeberg too, for example).

I’m very late to the party, but: no, iocaine does not expect you to detect the bots. It used to, but it does its own detection for quite a while now (you can replace the detection mechanism, though).
