+## [6.1.0] - 2026-04-06
+
+### Added
+
+- **`check_tool_input()` / `check_tool_output()`** — generic aliases for tool governance. Existing `mcp_check_input()` / `mcp_check_output()` remain supported.
+
+### Changed
+
+- Anonymous telemetry is now enabled by default for all endpoints, including localhost/self-hosted evaluation. Opt out with `DO_NOT_TRACK=1` or `AXONFLOW_TELEMETRY=off`.
