 # Changelog
 
+## [4.1.0](https://github.com/adcontextprotocol/adcp-client-python/compare/v4.0.0...v4.1.0) (2026-04-24)
+
+
+### ⚠ BREAKING CHANGES
+
+* **a2a:** `ADCPClient.pending_task_id` is now `ADCPClient.active_task_id` (same for `A2AAdapter`). The constructor's `context_id=` kwarg and `reset_context()` now raise `TypeError` (was `ValueError`) on non-A2A protocols — the string value is fine, the operation doesn't apply to MCP.
+
+### Features
+
+* **a2a:** checkpoint/from_checkpoint API, harden context-id retention ([a17ffb3](https://github.com/adcontextprotocol/adcp-client-python/commit/a17ffb382aa1d777e5e98fdc26c6cc9efd4898c0))
