Automations deep dive, and the release history through v0.22.0 - New Automations page: why one dispatcher rather than one job per automation, what the approval hash covers and what it deliberately does not, why `learning` is hashed only in the ON direction, why the pattern is admitted as untrusted notes, private-by-default and why unshare is not retroactive, and why a run is stopped by process group rather than pkill. - Home and sidebar carry it under The surfaces. - Release history was contiguous only to v0.18.0; adds v0.20.x, v0.21.0 and v0.22.0.
