Releases
What changed, and when
Every release, and why we made it. Anything that breaks carries a note on what to change and by when.

v2.4.0
4 September 2026

v2.3.0
21 August 2026
Give a new rule a grace period
A new rule can now report without stopping anything until a date you pick, so tightening a rule no longer means fixing every service the same afternoon.

v2.2.0
7 August 2026

Exports now carry the key that signed them, so an auditor can check the history themselves without an account and without asking us.

v2.1.0
17 July 2026

v2.0.0
26 June 2026

The agent is gone. Checks now run as a single 12MB program that reads what is about to change and answers pass or fail — the same way everywhere you run it.
