+
+
+### Features
+
+* Updated to use per-execution tracker lifecycle via `create_tracker()` instead of static tracker instances
+* Renamed graph metrics method from `track_latency()` to `track_duration()` for consistency
+* Moved graph_key configuration from graph tracker instantiation to node tracker initialization
+* Removed graph_key parameter from node-level tracker methods as it is now set during tracker creation
+
+### Dependencies
+
+* Updated for compatibility with `launchdarkly-server-sdk-ai` 0.18.0

 All notable changes to the LaunchDarkly Python AI package will be documented in this file. This project adheres to [Semantic Versioning](http://semver.org).
 
+## [0.18.0](https://github.com/launchdarkly/python-server-sdk-ai/compare/launchdarkly-server-sdk-ai-0.17.0...launchdarkly-server-sdk-ai-0.18.0) (2026-04-21)
+
+
+### ⚠ BREAKING CHANGES
+
+* Add per-execution runId, at-most-once tracking, and cross-process tracker resumption ([#133](https://github.com/launchdarkly/python-server-sdk-ai/issues/133))
+* `AICompletionConfig`, `AIAgentConfig`, and `AIJudgeConfig`: `tracker` field replaced with `create_tracker` factory callable ([#133](https://github.com/launchdarkly/python-server-sdk-ai/issues/133))
+* `ManagedModel`, `ManagedAgent`, `Judge`, and `ManagedAgentGraph` constructors no longer accept a tracker parameter; tracker is now created on-demand via `create_tracker` ([#133](https://github.com/launchdarkly/python-server-sdk-ai/issues/133))
+* `ManagedAgentGraph.get_tracker()` method removed ([#133](https://github.com/launchdarkly/python-server-sdk-ai/issues/133))
+* rename track_latency to track_duration on AIGraphTracker ([#138](https://github.com/launchdarkly/python-server-sdk-ai/issues/138))
+* `graph_key` keyword argument removed from all `LDAIConfigTracker.track_*()` methods; trackers retrieved via a graph definition are automatically configured with the correct graph key ([#134](https://github.com/launchdarkly/python-server-sdk-ai/issues/134))
+* Flatten JudgeResponse and EvalScore into new JudgeResult ([#132](https://github.com/launchdarkly/python-server-sdk-ai/issues/132))
+* `LDAIConfigTracker.track_eval_scores()` and `track_judge_response()` removed and consolidated into `track_judge_result()` ([#132](https://github.com/launchdarkly/python-server-sdk-ai/issues/132))
+* `AIGraphTracker.track_judge_response()` method removed ([#132](https://github.com/launchdarkly/python-server-sdk-ai/issues/132))
+* `Judge.evaluate()` and `evaluate_messages()` now always return a `JudgeResult` object; use `result.sampled` to check if evaluation was actually executed ([#132](https://github.com/launchdarkly/python-server-sdk-ai/issues/132))
+
+### Features
+
+* Add per-execution runId, at-most-once tracking, and cross-process tracker resumption ([#133](https://github.com/launchdarkly/python-server-sdk-ai/issues/133)) ([68685cd](https://github.com/launchdarkly/python-server-sdk-ai/commit/68685cd9623105b0b01dd57942538c047615f4f2))
+* Flatten JudgeResponse and EvalScore into new JudgeResult ([#132](https://github.com/launchdarkly/python-server-sdk-ai/issues/132)) ([af4e463](https://github.com/launchdarkly/python-server-sdk-ai/commit/af4e46332c5d9a668a7172012c89871d0fb90b56))
+* Move graph_key to AIConfigTracker instantiation ([#134](https://github.com/launchdarkly/python-server-sdk-ai/issues/134)) ([20fff24](https://github.com/launchdarkly/python-server-sdk-ai/commit/20fff24fcd02aa101d7f9a6c21dc6a25e7916a1c))
+* rename track_latency to track_duration on AIGraphTracker ([#138](https://github.com/launchdarkly/python-server-sdk-ai/issues/138)) ([05758a7](https://github.com/launchdarkly/python-server-sdk-ai/commit/05758a735db0c2defc4e08d02282a46f559220e5))
+* Add `LDAIConfigTracker.resumption_token()` and `from_resumption_token()` methods to continue tracking a run from a separate process ([#133](https://github.com/launchdarkly/python-server-sdk-ai/issues/133)) ([68685cd](https://github.com/launchdarkly/python-server-sdk-ai/commit/68685cd9623105b0b01dd57942538c047615f4f2))
