    <description>MQTTnet is a high performance .NET library for MQTT based communication. It provides a MQTT client and a MQTT server (broker) and supports v3.1.0, v3.1.1 and v5.0.0 of the MQTT protocol.</description>
    <releaseNotes>
-* [Core] Added .NET 5.0 TFMs (thanks to @StefanOssendorf, @JanEggers).
-* [Core] Added support for TLS 1.3 (requires .NET Core 3.1+) (thanks to @Dvergatal).
-* [Core] Added support for _MaximumQoS_ transmit when using MQTTv5 (thanks to @nayato).
-* [Core] Aligned the format of some log messages.
-* [Client] Fixed an issue with connection state detection (thanks to @tobiasfrick).
-* [Client] Fixed an issue when receiving partial QoS 2 packets after a reconnect.
-* [Client] Added new API for raw packet inspection.
-* [ManagedClient] Removed _AutoReconnect_ since this does no longer work (BREAKING CHANGE!).
-* [RpcClient] Moved the RPC topic validation to the topic generation strategy.
-* [RcpClient] Added interface for _MqttRpcClient_.
-* [Server] Reduced async tasks count by moving dedicated keep alive tasks per connection to shared one.
-* [Server] Session takeover and keep alive timeout are now properly set in DISCONNECT packet.
-* [Server] Fixed bug in PubRel packet generation (MQTTv5 only).
-* [Server] Improved message processing performance (+ ~5%).
-* [Server] Fix wrong usage of client session items for undelivered messages.
-* [Server] Allow to respond with a reason code in PUBACK/PUBREC (thanks to @muneebmajeed).
-* [Server] Fixed topic filter comparer on edge cases, e.g. "foo/" matching "foo/#" (thanks to @dagophil).
-* [Core] Added code documentation.
+* [Client] Increased delay for keep alive checks do decrease CPU load.
+* [Core] Decreased object allocations (#1324, thanks to @gfoidl).
+* [Core] Decreased object allocations when logging is not active (thanks to @gfoidl, @Tymoniden).
+* [Client] Fixed issue in _MqttApplicationMessageBuilder.WithPayload_ (#1322, thanks to @gfoidl).

-# MQTT Scripts
-
-This directory contains scripts which are loaded by the server and can be used to perform the following tasks.
-
-* Validation of client connections via credentials, client IDs etc.
-* Manipulation of every processed message.
-* Validation of subscription attempts.
-* Publishing of custom application messages.
-
-All scripts are loaded and _MQTTnet Server_ will invoke functions according to predefined naming conventions.
-If a function is implemented in multiple scripts the context will be moved throug all instances. This allows overriding of results or passing data to other (following) scripts.
-
-The Python starndard library ships with _MQTTnet Server_. But it is possible to add custom paths with Python libraries.
-
-```
-import sys
-sys.path.append(PATH_TO_LIBRARY)
-```
-
-* All scripts must have the file extension _.py_. 
-* All scripts are sorted alphabetically (A to Z) before being loaded and parsed.
