-## 2.21.2
+## 3.2.2
+### Bug Fixes
+
+- ASM
+  - Fixes a `NotImplementedError` that occurred when trying to deepcopy wrapped builtin functions (like `open`) while ASM or IAST were enabled. The error was caused by the wrapper not implementing the `__deepcopy__` method.
+  - SCA: Resolves an issue where some dependencies where reported with an inaccurate name.
 
 
+- CI Visibility
+  - Resolves an issue where JUnit XML output would not count tests retried by Early Flake Detection, Auto Test Retries, and Attempt-to-Fix.
+
+- LLM Observability
+  - Resolves issue where Pydantic model objects were encoded as unhelpful default placeholder text.
+  - Improves encoding of non-JSON serializable I/O objects by attempting to convert to string before resorting to default placeholder text.
+
+- Profiling
+  - Resolves an issue where the Lock profiler would throw an `AttributeError: '_ProfiledThreadingLock' object has no attribute '_self_acquired_at'`.
+
+- Tracing
+  - pylibmc: Fixes an issue where using `Client(server=[url])` would throw the error `__init__() got multiple values for argument 'servers'`

+## 2.21.2
+### Bug Fixes
 - single-step instrumentation: Removes `boto3` from the minimum versions list to avoid blocking SSI on `boto3` version.

 - ASM: This fix resolves an issue where blocking mechanism could partially fail with a 500 error on fastapi with python\>=3.11 with a custom middleware.
