## TLDR

* **Why Upgrade**
    - Performance Improvements for /v1/messages: For this endpoint LiteLLM Proxy overhead is now down to 50ms at 250 RPS. 
    - Accurate Rate Limiting: Multi-instance rate limiting now tracks rate limits across keys, models, teams, and users with 0 spillover.
    - Audit Logs on UI: Track when Keys, Teams, and Models were deleted by viewing Audit Logs on the LiteLLM UI.
    - /v1/messages all models support: You can now use all LiteLLM models (`gpt-4.1`, `o1-pro`, `gemini-2.5-pro`) with /v1/messages API. 
    - [Anthropic MCP](../../docs/providers/anthropic#mcp-tool-calling): Use remote MCP Servers with Anthropic Models. 
* **Who Should Read**
    - Teams using `/v1/messages` API (Claude Code)
    - Proxy Admins using LiteLLM Virtual Keys and setting rate limits
* **Risk of Upgrade**
    - **Medium**
        - Upgraded `ddtrace==3.8.0`, if you use DataDog tracing this is a medium level risk. We recommend monitoring logs for any issues.

## `/v1/messages` Performance Improvements

<Image 
  img={require('../../img/release_notes/v1_messages_perf.png')}
  style={{width: '100%', display: 'block', margin: '2rem auto'}}
/>

This release brings significant performance improvements to the /v1/messages API on LiteLLM. 

For this endpoint LiteLLM Proxy overhead latency is now down to 50ms, and each instance can handle 250 RPS. We validated these improvements through load testing with payloads containing over 1,000 streaming chunks.

This is great for real time use cases with large requests (eg. multi turn conversations, Claude Code, etc.). 

## Multi-Instance Rate Limiting Improvements

<Image 
  img={require('../../img/release_notes/multi_instance_rate_limits_v3.jpg')}
  style={{width: '100%', display: 'block', margin: '2rem auto'}}
/>

LiteLLM now accurately tracks rate limits across keys, models, teams, and users with 0 spillover.

This is a significant improvement over the previous version, which faced issues with leakage and spillover in high traffic, multi-instance setups.

**Key Changes:**
- Redis is now part of the rate limit check, instead of being a background sync. This ensures accuracy and reduces read/write operations during low activity.
- LiteLLM now uses Lua scripts to ensure all checks are atomic.
- In-memory caching uses Redis values. This prevents drift, and reduces Redis queries once objects are over their limit.

These changes are currently behind the feature flag - `EXPERIMENTAL_ENABLE_MULTI_INSTANCE_RATE_LIMITING=True`. We plan to GA this in our next release - subject to feedback.

## Audit Logs on UI

<Image 
  img={require('../../img/release_notes/ui_audit_log.png')}
  style={{width: '100%', display: 'block', margin: '2rem auto'}}
/>

This release introduces support for viewing audit logs in the UI. As a Proxy Admin, you can now check if and when a key was deleted, along with who performed the action.

LiteLLM tracks changes to the following entities and actions: 

- **Entities:** Keys, Teams, Users, Models
- **Actions:** Create, Update, Delete, Regenerate
