JSON body dropped when files provided
Medium Severity
_build_request now skips JSON serialization whenever files is present. For requests that pass both json_data and files without an explicit multipart Content-Type path, json_data is silently omitted and only file parts are sent. This changes request semantics and can drop required non-file fields.

Null JSON payload no longer sent
Low Severity
Switching from kwargs["json"] to kwargs["content"] now skips serialization when json_data is None, so body-less non-GET requests send an empty payload instead of JSON null. This changes wire behavior for endpoints that distinguish empty body from explicit null.

Note
Medium Risk
Medium risk because it changes core request-body serialization (switching some JSON payloads to custom byte encoding) and touches SSE streaming plumbing, which could affect API request/stream behavior across the SDK.
Overview
Bumps the SDK to v0.9.0 (manifest/pyproject/version file), refreshes the tracked OpenAPI spec, and updates generated API types including adding
mcp_servers/ConfigMcpServertoconverseconfig and expanding supportedllm_modelliterals (e.g.gemini-3-flash-preview).Updates the HTTP client to use a new
openapi_dumps()JSON serializer (supportingdatetime+pydantic.BaseModelwith aliases) when building request bodies, adjustsmodel_dump()compat to acceptby_alias, and threads requestoptionsthrough SSEStream/AsyncStreamconstruction.Also tightens CI/release tooling: skips OIDC/artifact uploads on
stl/*branches and upgradesactions/github-script, improves./scripts/mockdaemon startup reliability/timeouts, updates formatting to run across allapi.mdfiles, bumps lockfile dependencies, and makes proxy/file-related tests more resilient.Written by Cursor Bugbot for commit 4282013.
