owner_type is no longer accepted

What changed

Usually ignored rather than rejected, so the call succeeds and does something subtly different.

Affects owner_type on POST /agents/repos/{owner}/{repo}/automations. Grep for it: nothing else will tell you.

Who is affected

Code that sends POST /agents/repos/{owner}/{repo}/automations (owner_type).

Before and after

Code that breaks

await client.post("/agents/repos/{owner}/{repo}/automations", {
  // owner_type is now ignored, not rejected
  owner_type: value,
});

Based on GitHub’s published API specification. How severity is decided.
