+`v1.88.3` is a patch release on top of [`v1.88.2`](/release_notes/v1.88.2/v1-88-2). It fixes two guardrail regressions: database-backed guardrails were being re-initialized on every poll, and model-level guardrails ran their pre-call hook more than once.
+
+### What's Changed
+
+- fix(guardrails): stop re-initializing DB guardrails on every poll - [PR #30542](https://github.com/BerriAI/litellm/pull/30542)
+- fix(guardrails): run the `pre_call` hook once for model-level guardrails - [PR #30543](https://github.com/BerriAI/litellm/pull/30543)

+`v1.89.1` is a patch release on top of [`v1.89.0`](/release_notes/v1.89.0/v1-89-0). It brings the 1.84.8 database-resilience set onto the 1.89 line, hardens the MCP OAuth and credential paths, aligns the `/v1/model/info` and `/v2/model/info` surfaces, adds the budget-reservation toggle, and refreshes dependencies.
