 ## Key Highlights
 
 - **Dynamic Rate Limiter v3** - Automatically maximizes throughput when capacity is available (< 80% saturation) by allowing lower-priority requests to use unused capacity, then switches to fair priority-based allocation under high load (≥ 80%) to prevent blocking
-- **Major Performance Improvements** - Router optimization reducing P99 latency by 62.5%, cache improvements from O(n*log(n)) to O(log(n))
+- **Major Performance Improvements** - 2.9x lower median latency at 1,000 concurrent users.
 - **Claude Sonnet 4.5** - Support for Anthropic's new Claude Sonnet 4.5 model family with 200K+ context and tiered pricing
 - **MCP Gateway Enhancements** - Fine-grained tool control, server permissions, and forwardable headers
 - **AMD Lemonade & Nvidia NIM** - New provider support for AMD Lemonade and Nvidia NIM Rerank
 - **GitLab Prompt Management** - GitLab-based prompt management integration

 This update removes LiteLLM router inefficiencies, reducing complexity from O(M×N) to O(1). Previously, it built a new array and ran repeated checks like data["model"] in llm_router.get_model_ids(). Now, a direct ID-to-deployment map eliminates redundant allocations and scans.
 
 As a result, performance improved across all latency percentiles:
 
-- **Median latency:** 600 ms → **280 ms** (−53%)
-- **p95 latency:** 1,900 ms → **520 ms** (−72%)
-- **p99 latency:** 3,000 ms → **1,000 ms** (−62.5%)
+- **Median latency:** 320 ms → **110 ms** (−65.6%)
+- **p95 latency:** 850 ms → **440 ms** (−48.2%)
+- **p99 latency:** 1,400 ms → **810 ms** (−42.1%)
 - **Average latency:** 864 ms → **310 ms** (−64%)
 
 Overall throughput increased to ~1,880 RPS (aggregated) per instance, while maintaining low overhead (~27 ms average).
