+
+### v0.18.13: Enhanced Provider Quota Management and Cooldown Logic
+
+### New Features & Improvements
+
+- **Optimized Cooldown and Quota Management**: Enhanced the system's ability to process provider-supplied quota reset metadata. When resource usage exceeds 99%, the system now implements a targeted cooldown until the verified end of the period, replacing the generic exponential backoff strategy ([43674d7](https://github.com/mcowger/plexus/commit/43674d7)).
+- **NanoGPT Quota Checker**: Refined the parser and logic for the NanoGPT quota checker to improve usage tracking accuracy ([7b4281c](https://github.com/mcowger/plexus/commit/7b4281c)).
+
+The docker image has been updated and can be found at ghcr.io/mcowger/plexus:latest
