Secure channels can be either configured through new connection parameters to be specified in the `/mqtt_connectors/mqtt_master_connector_conf.xml` file, or by deploying custom Hooks that provide instances of the new `SecurityParams` class. See docs for more information. - Added new sample configurations in `/mqtt_connectors/mqtt_master_connector_conf.xml`, along with related _JKS_ sample files, to show how to configure encrypted connections. - Added the dedicated `MQTTCoolLogger.connections.ssl` logger in `/mqtt_connectors/mqtt_master_connector_log_conf.xml`, to report issues relative to TLS/SSL handshake management. Changed default logging levels and improved inline comments of many loggers. - Enabled the Test Client to specify the protocol to use for each new broker configuration. Users can now set up either plain or TLS/SSL connection by selecting the right schema from a list. Improved management of broker configurations: it is now possible to change all parameters of the selected configuration. **Bug Fixes** - Fixed a bug that, in the case of only one client connected through a _Shared Connection_, prevented an unsubscribe request from reaching the MQTT broker. - Fixed generation of log messages for the `MQTTCoolLogger` logger. Added and improved log messages for initialization activities. **1.0.3 b2 build 279 (16 Nov 2017)** ------------------------------------ **Improvements** - Introduced a very simple MQTT.Cool test client (a.k.a _Test Client_), which can be launched from the Welcome page, for the purpose of testing the interaction between the MQTT.Cool server and MQTT brokers. **1.0.3 b1 build 266 (29 Sep 2017)** ------------------------------------ First public release.
