LiteLLM 1.98 adds deprecation alerts and gateway security controls
LiteLLM 1.98 added proactive model-retirement alerts and a deprecations endpoint, stripped callback credentials from request metadata, scoped file pagination to the caller, introduced deployment-specific failure and cooldown policies, and published signed-container verification instructions.
Why it matters: The release addresses lifecycle visibility, credential leakage, tenant isolation, fallback behavior, and supply-chain verification at a shared model-gateway boundary.
