`v1.91.3` is a patch release on top of `v1.91.2`. It backports two changes onto the 1.91.x line. The first restores guardrail coverage on the Responses API: shared content helpers now walk the Responses item taxonomy, so text guardrails once again see user and tool-output text on `/v1/responses` instead of scanning an empty payload. The second records a failed LLM call as the GenAI-standard `gen_ai.client.operation.exception` log event, carrying the exception type, message, and stacktrace at WARN severity so observability backends see the full failure.

### What's Changed

- fix(guardrails): walk Responses-API text taxonomy in shared content helpers - [PR #32542](https://github.com/BerriAI/litellm/pull/32542)
- feat(otel): emit the gen_ai.client.operation.exception event on failed LLM calls - [PR #32655](https://github.com/BerriAI/litellm/pull/32655)
