`v1.90.4` is a patch release on top of [`v1.90.3`](/release_notes/v1.90.3/v1-90-3). It restores text guardrail coverage on the Responses API (`/v1/responses`). The shared guardrail content helpers now walk the Responses `input` taxonomy (the `text`, `input_text`, and `output_text` part types, and `message`, `function_call`, and `function_call_output` items), so guardrails that build on those helpers (AIM, Lakera v2, Cato, Lasso, Repello, IBM, Azure Content Safety, and enterprise secret detection) inspect and redact request text on `/v1/responses` the same way they already do for chat completions.

### What's Changed

- fix(guardrails): walk Responses-API text taxonomy in shared content helpers - [PR #32542](https://github.com/BerriAI/litellm/pull/32542)
