- - aws: fixed a race where the route-level configuration of the AWS request signing and AWS Lambda filters could be destroyed on a worker thread when an RDS update replaced the route configuration.

- - dynamic_modules: fixed a bug where the per-route config destroy hook could run on a worker thread, and the module could be unloaded there, when an RDS update replaced the route configuration.
- - filter_chain: fixed a race where the route-level configuration of the filter chain filter could be destroyed on a worker thread when an RDS update replaced the route configuration.
- - local_ratelimit: fixed a race where the share provider manager owned by a local rate limit route-level configuration could be destroyed on a worker thread.
- - sds: fixed a race where a generic secret provider shared with worker threads could be destroyed on a worker thread.
