+Full Changelog: [v0.11.5...v0.11.6](https://github.com/scaleapi/scale-agentex-python/compare/v0.11.5...v0.11.6)
+
+### Features
+
+* **api:** add cleaned_at field to task response types ([38ed338](https://github.com/scaleapi/scale-agentex-python/commit/38ed3384094f7f07f6b2482489f457fd1dc4f76d))
+* **deps:** bump openai-agents to >=0.14.3 for scale-sandbox oai_agents adapter ([#375](https://github.com/scaleapi/scale-agentex-python/issues/375)) ([e1b31d9](https://github.com/scaleapi/scale-agentex-python/commit/e1b31d91abadec572989b805592b788500d61994))
+* **lib:** expose data_converter kwarg on AgentexWorker and Temporal client APIs ([#372](https://github.com/scaleapi/scale-agentex-python/issues/372)) ([d04624e](https://github.com/scaleapi/scale-agentex-python/commit/d04624e6899e43a0429ef2deeb84509265b9f636))
+
+
+### Bug Fixes
+
+* **tutorials:** restore tutorial CI deps after agentex-sdk 0.11.5 (pytest + debugpy) ([#379](https://github.com/scaleapi/scale-agentex-python/issues/379)) ([0a2418c](https://github.com/scaleapi/scale-agentex-python/commit/0a2418cc9f9b06e3bdc46099106e50d226412fa0))
+
+
+### Performance Improvements
+
+* **tracing:** span queue linger + per-loop httpx keepalive ([#362](https://github.com/scaleapi/scale-agentex-python/issues/362)) ([feec842](https://github.com/scaleapi/scale-agentex-python/commit/feec8426f79e9f02533451d44997717655fd33f2))
+
+
+### Chores
+
+* back-merge release 0.11.5 into next ([#381](https://github.com/scaleapi/scale-agentex-python/issues/381)) ([ab5a7d9](https://github.com/scaleapi/scale-agentex-python/commit/ab5a7d9732a56d47efad469675c7630046106ef6))
+* **deps:** drop unused runtime deps and exclude tests from wheel ([#367](https://github.com/scaleapi/scale-agentex-python/issues/367)) ([f4303d1](https://github.com/scaleapi/scale-agentex-python/commit/f4303d1e7211783d19beca6554e44eb73bb29c42))
+
+
+### Refactors
+
+* **types:** promote protocol types to agentex.protocol.* ([#371](https://github.com/scaleapi/scale-agentex-python/issues/371)) ([6f1c14f](https://github.com/scaleapi/scale-agentex-python/commit/6f1c14fd61077da52038361642a9fbc4a0a56c8b))
