Changed
- Rate limiting for downlink queue operations (
DownlinkQueuePush,DownlinkQueueReplace) is now applied at the application level instead of per-device. This may result in moreResourceExhausted(429) errors when multiple devices under the same application perform downlink queue operations concurrently.
Fixed
- Application Server webhook registry now uses read-only Redis client for non-paginated list operations, reducing connection holding time during high traffic.
