`v1.90.1` is a patch release on top of [`v1.90.0`](/release_notes/v1.90.0/v1-90-0). It backports three fixes onto the 1.90.x line: Vertex AI batch-file uploads switch to a single media upload so large uploads no longer fail with 499 errors, OpenAI→Vertex batch JSONL uploads stream instead of buffering in memory, and the API key is redacted from `/key/info` client error messages. The bundled `litellm-enterprise` package is bumped to `0.1.43.post1`.

### What's Changed
