FASTAPI CORE DEPENDENCIES ADVANCE, STARLETTE JUMPS TO 1.2.1

By RepoJournal · Filed · About FastAPI & Pydantic

FastAPI's dependency stack is moving faster than usual: Starlette climbs two minor versions [ref:5], python-multipart patches a URL parsing fix [ref:4], and six supporting packages ship updates in a single sweep [ref:1].

The headline move is Starlette 1.2.1 [1], which swaps httpx for httpx2 in the testclient module. This matters because httpx2 2.3.0 [2] also ships in the same batch, meaning the upgrade is coordinated and tested together. Python-multipart 0.0.30 [3] tightens URL field separator handling to treat only ampersands as delimiters, a parsing fix that affects form handling. The broader dependency refresh [2] pulls in Ruff 0.15.15, Typer 0.26.6, and inline-snapshot 0.34.0 across the board. This is maintenance day, not a crisis. CI infrastructure also updates [4] with actions/checkout 6.0.3 to keep the build pipeline current.
