What’s New in v1.20.0
The wolfMQTT v1.20.0 release includes several significant enhancements:

WebSocket Support
The most notable addition in this release is comprehensive support for MQTT over WebSockets. This feature allows wolfMQTT clients to connect to MQTT brokers through WebSocket endpoints, which is particularly valuable in environments where traditional MQTT ports might be blocked or when integrating with web applications.

Both standard WebSockets and secure WebSockets (WSS) are now supported, providing flexibility for various security requirements:

• Standard WebSockets: Connect to brokers using the WebSocket protocol without encryption

• Secure WebSockets: Use TLS to encrypt the WebSocket connection for enhanced security

Secure WebSocket CI Testing
To ensure the reliability of the new WebSocket functionality, we’ve added continuous integration testing specifically for secure WebSockets. This testing helps maintain the high quality and stability that users expect from wolfMQTT.

Improved CMake Support
This release includes improvements to the CMake build system:

• Enhanced duplicate component checking in CMake builds

• Better compatibility with the latest Managed Components

Additional Improvements

• Updated examples for the latest Managed Components

• Fixed an issue with OQS’s Mosquitto being out of date
