New Feature
- Add concurrent request handling.
Improvements
- Reduce memory consumption under load.
- Standardize runtime error messages.
Release Date
- 2026-05-04
Improvements
- Enhance HTTP forwarding resilience by processing outbound requests with 8 workers and implementing a 30-second request timeout. This approach mitigates the impact of slow or unresponsive downstream endpoints.
- Add bounded input cache behavior that keeps up to 1024 readings and prioritizes the latest data when forwarding falls behind.
- Add StoreForward fallback for input cache overflow so the oldest cached readings can be preserved when StoreForward is available.
Bug Fix
- Fix outbound HTTP requests to consistently send request bodies with them Content-Length instead of unexpectedly using Transfer-Encoding: chunked.
- Fix unbounded input cache growth that could contribute to high memory consumption when HTTP forwarding cannot keep up with incoming data.
