Pydantic announced it is picking up stewardship of the largely dormant HTTPX client under the name HTTPX2 (pydantic/httpx2, BSD-3, sync+async, HTTP/2, built-in CLI, Logfire observability), and the same day the OpenAI Python SDK published its 'Migrating to HTTPX2' guide — the first major ecosystem consumer to commit. Two separate Aug 28 Hacker News threads (196 and 120 points) discussed the fork and the migration.
