📋 Detailed Changelog Review

python-multipart (0.0.26 → 0.0.27)

Released 2026-04-27. Two changes per the release notes:

• #267 — Add multipart header limits. Adds new constructor-level limits for multipart header parsing (a hardening / DoS-resistance feature). Defaults are conservative; existing callers that don't supply the new args are unaffected.

• #268 — Pass parse offsets via constructors. Internal refactor of how parse offsets are threaded through. Affects the low-level parser API surface, not high-level FastAPI/Starlette/MCP form handling.

• Breaking changes: None for downstream framework users. Both changes are additive at the public API level.

• Security fixes: No CVE called out, but the new header-limit knobs are defense-in-depth for multipart parsing.

• Migration notes: None required.

---

⚠️ Impact Assessment

• How OCS pulls it in: python-multipart is not a direct dependency. It is pulled in transitively as: langchain-mcp-adapters → mcp → python-multipart (confirmed in uv.lock).
• Direct usage: A search for from multipart, import multipart, or python_multipart in apps/ returned zero hits. The only multipart references in the codebase are:
  • DRF test clients using format="multipart" (Django/DRF, not python-multipart)
  • enctype="multipart/form-data" in form attributes (HTML, not python-multipart)
• Affected files: None.
• Test impact: None expected. Existing form-upload tests (apps/api/tests/test_chat_file_upload_api.py, etc.) go through Django/DRF, not python-multipart directly.
• Configuration changes: None.

---

🛠️ Recommendations

• Action Required: None beyond standard CI green check.
• Testing Focus: Run the existing test suite — particularly any MCP-related flows (since mcp is the consumer of this package). File-upload paths through Django/DRF are unaffected.
• Follow-up Tasks: None.
• Merge Recommendation: ✅ APPROVE (assuming CI passes).
