The release candidate cut September 13 adds Azure Mistral in standard and native-auth variants, Azure Document Intelligence, Reducto legacy and v3, Vertex Mistral and Vertex DeepSeek OCR adapters, and PR #40509 removes the old pipeline instead of deprecating it.

Released September 1, leading its notes with cosign verification for ghcr.io/berriai/litellm, recommending verification against the public key at pinned commit 0112e53 because a commit hash is cryptographically immutable, with tag-based verification offered as the weaker optio...
The RC published August 30 adds a complexity_router rule sending client housekeeping calls to the cheapest model tier, and reports prompt caching savings as two numbers, total and gateway-attributed, so you can tell what the proxy saved you from what the provider would have ca...
Google's Agent Development Kit for Python listed litellm>=1.75.5 as an optional dependency. No upper bound. No pin. During the week of March 24, LiteLLM versions 1.82.7 and 1.82.8 were compromised by the TeamPCP group with a three-stage payload: credential harvesting, Kubernet...
