 # Change Log - @typespec/http-client-python
 
+## 0.29.0
+
+### Deprecations
+
+- [#10500](https://github.com/microsoft/typespec/pull/10500) Drop support for Python 3.9. The minimum supported Python version is now 3.10. Python 3.9 reached end-of-life and is no longer supported by upstream Python.
+
+### Features
+
+- [#10378](https://github.com/microsoft/typespec/pull/10378) Add "Use with AI tools" section to Azure packages README template
+- [#10587](https://github.com/microsoft/typespec/pull/10587) add `CrossLanguageVersion` to `apiview-properties.json`
+
+### Bug Fixes
+
+- [#10399](https://github.com/microsoft/typespec/pull/10399) Fix enum member names with hyphens generating invalid Python identifiers
+- [#10385](https://github.com/microsoft/typespec/pull/10385) Fix grouped parameter attribute access for reserved words in code generation
+- [#10303](https://github.com/microsoft/typespec/pull/10303) fix import for _validation.py/_types.py when "generation-subdir" is configured
+- [#10494](https://github.com/microsoft/typespec/pull/10494) Support custom wire names for etags defined with `Azure.Core.eTag` (e.g. `x-ms-blob-if-match`)
+- [#10546](https://github.com/microsoft/typespec/pull/10546) Fix serialization regression where `@clientDefaultValue` defaults on model properties were no longer included in the request body. Defaults are again materialized in the model's data dictionary at construction time so they are sent on the wire, while the attribute-access fallback for unset fields is preserved.
+- [#10254](https://github.com/microsoft/typespec/pull/10254) Contain emitter changes when used with `generation-subdir` to solely within that subdirectory
+- [#10328](https://github.com/microsoft/typespec/pull/10328) Pass `headers` kwarg through to next requests in paging calls
+- [#10326](https://github.com/microsoft/typespec/pull/10326) Fix padding of keys in splatted body parameter method signature
+- [#10557](https://github.com/microsoft/typespec/pull/10557) Update Python emitter browser behavior to only load Pyodide once instead of on every emit
+- [#10348](https://github.com/microsoft/typespec/pull/10348) Refine `api_version` argument doc to show `None` as default value and include note about operation's default API version being used when not set
+- [#10545](https://github.com/microsoft/typespec/pull/10545) Revert wrong code to avoid overwrite customized code when generation-subdir is set
