 ### Security

 - Any simultaneous requests that are considered duplicates will now only result in a single request to upstreams, reducing the chance of a cache poisoning attack succeeding.  This is controlled by the new configuration object `pending_requests`, which has a single `enabled` property, set to `true` by default.

    **NOTE:** We thank [Xiang Li][mr-xiang-li] for reporting this security issue.  It's strongly recommended to leave it enabled, otherwise AdGuard Home will be vulnerable to untrusted clients.

+- Searching for persistent clients using an exact match for CIDR in the `POST /clients/search HTTP API`.
