##
[3.0.0](openai/openai-python@v2.54.0...v3.0.0)
(2026-08-12)


### ⚠ BREAKING CHANGES

* **api:** HTTPX2 is now the default HTTP client, and `httpx` is no
longer installed automatically. Applications using custom HTTPX clients,
transports, or configuration objects must migrate to their HTTPX2
equivalents or use the temporary, runtime-only legacy HTTPX escape
hatch. See the [HTTPX2 migration
guide](https://github.com/openai/openai-python/blob/main/httpx2.md).

### Features

* **api:** migrate to HTTPX2
([openai#3594](openai#3594))
