# 2.0 rework vs 1.x: the low-level transport moved from httpx to httpx2 (the
# Pydantic httpx fork; ::gentoo's httpx2 bundles httpcore2), the shared wire
# types split out to dev-python/mcp-types (== pinned), and opentelemetry-api
# was added. httpx-sse and pydantic-settings are no longer imported.

# 2.0 switched the version source to the uv-dynamic-versioning hatch plugin,
# which derives from VCS; the sdist is not a checkout, so pin it explicitly.
