Bumps google-genai from 2.34.0 to 3.0.0.

Release notes

Sourced from google-genai's releases.

v3.0.0

3.0.0 (2026-11-05)

⚠ BREAKING CHANGES

• Default Gemini Developer API version is now v1 (was v1beta) (2d0f947)

  • Clients targeting the Gemini Developer API now default to API version v1 instead of v1beta.
  • No effect on Gemini Enterprise (Vertex AI) defaults: Clients with vertexai=True / enterprise=True are unaffected by this default change and continue to default to v1beta1.
  • Some model aliases are not available on v1, notably: gemini-flash-latest, gemini-flash-lite-latest and gemini-pro-latest. They exist only on v1beta. To keep using them, use a specific model version, or switch back to v1beta as shown below.
  • How to configure or restore the previous default via environment variable: Set GOOGLE_GENAI_API_VERSION (works for both Gemini Developer API and Enterprise / Vertex AI clients when no version is set in code):

    # Restores the beta default ('v1beta' on Gemini Developer API, 'v1beta1' on Enterprise / Vertex AI)
    export GOOGLE_GENAI_API_VERSION=beta
    Or set an explicit API version string on either platform (e.g. 'v1', 'v1beta', 'v1beta1')
    export GOOGLE_GENAI_API_VERSION=v1beta

  • How to set the API version in code: Pass api_version in HttpOptions (takes precedence over GOOGLE_GENAI_API_VERSION):

    from google import genai
    from google.genai import types
    client = genai.Client(
    http_options=types.HttpOptions(api_version='v1beta')
    )

• Default HTTP client is now httpx2 (was httpx), and httpx is no longer installed by default (51285c8)

  • httpx is no longer installed by default. httpx2 is now the required dependency and default HTTP client.
  • How to restore the previous httpx default via environment variable: Because httpx2 is installed by default, installing google-genai[httpx] alone only makes import httpx available; to switch the SDK's default client back to httpx without code changes, both install the httpx extra and set GOOGLE_GENAI_HTTP_CLIENT=httpx:

    pip install "google-genai[httpx]"
    export GOOGLE_GENAI_HTTP_CLIENT=httpx

  • How to pass an httpx client in code: After installing google-genai[httpx], you can pass httpx.Client / httpx.AsyncClient directly via HttpOptions:

    import httpx
    from google import genai
    from google.genai import types
    client = genai.Client(
    http_options=types.HttpOptions(
    httpx_client=httpx.Client(),
    httpx_async_client=httpx.AsyncClient(),
    )
    )

  • Migrating existing httpx code to httpx2: In most cases, updating your imports with import httpx2 as httpx is sufficient.
  • SSL certificate verification: By default, httpx2 uses the OS certificate trust store (via truststore / httpx2.create_ssl_context()) instead of certifi when SSL_CERT_FILE and SSL_CERT_DIR are not set.
  • When httpx vs. httpx2 types matter: Package-specific objects passed in HttpOptions(client_args=..., async_client_args=...) (such as Timeout, Limits, MockTransport / BaseTransport, or custom Auth subclasses) and unwrapped transport exceptions caught from client.models, client.files, etc. (TimeoutException, ConnectError, HTTPError) must match the active HTTP client. (When GOOGLE_GENAI_HTTP_CLIENT is unset or auto, passing httpx objects in HttpOptions will also auto-select the httpx backend if google-genai[httpx] is installed.)

🕒 Major-version bump (google-genai). Not auto-merged — held for human review per policy in .github/workflows/dependabot-automerge.yml.

✅ Approved

🤖 Claude Sonnet 4.6 (claude-sonnet-4-6) via claude-bridge · mode: council (specialists + arbiter) · run

Dependency-only bump of google-genai from 2.34.0 to 3.0.0. The two breaking changes in this major release (API version default v1beta→v1 and httpx→httpx2 HTTP backend) are real migration concerns, but the diff shows only manifest/lockfile changes — no call sites are visible, so neither finding can be carried as a blocking defect per the load-bearing-premise rule. Approve with awareness nits.

No blocking findings — clean diff.

Non-blocking suggestions (2):

• ⚪ packages/code-review-council/pyproject.toml:20 — google-genai 3.0.0 defaults to API version v1; model aliases like gemini-flash-latest / gemini-pro-latest only exist on v1beta. Audit call sites for such aliases and either swap to versioned names (e.g. gemini-1.5-flash-002) or set GOOGLE_GENAI_API_VERSION=v1beta in the runner env.
• ⚪ uv.lock:886 — google-genai 3.0.0 replaces httpx with httpx2 as the default HTTP backend. If any call site passes httpx-typed objects via HttpOptions or catches httpx transport exceptions, migrate those to httpx2 equivalents (or use google-genai[httpx] + GOOGLE_GENAI_HTTP_CLIENT=httpx to restore the old backend).
