  • Tmax-27B hybrid-cache fix. is_hybrid: true on all Tmax-27B variants — was incorrectly false in 0.8.18, which corrupted the RNN state on prefix-cache hits (PR #902).
  • Responses item shape defaults to type: "message" when role+content are present (PR #904).
  • thinking accounting. enable_thinking now threads into prompt accounting on the chat + responses paths so reasoning models report token usage correctly (PR #906, follow-up to #891).
  • Auto-config routing. V4 / V5 model-type detection aligned with the alias classifier (PR #903).
  • CLI: rapid-mlx serve now exits non-zero on a port-already-in-use error (PR #905).
  • CI: pr_validate full_unit flakes on macOS uv-managed Python fixed (PR #907).
