Breaking Changes

• SystemClock::now() returns time_t instead of DateTime.

If you use Websocket functionality make sure to read the notes below.

This is a minor release containing fixes, new features and coding style rules.

Coding Style Rules

• This is the first version in which we started forcing our coding style rules. The coding style rules are applied to the SmingCore and samples directories and their sub-directories. The coding style rules use clang-format to automate the process. You should format your code changes before submitting a PR. This can be done, after installing the clang-format application, with the command

cd $SMING_HOME
make cs

More information about the coding style and ways to integrate automatic fixes in your Eclipse IDE can be found in our Wiki page.

Features

• Added support for the DFPlayerMini ( #1408 )

Bug fixes and small improvements

• Fix to the SmtpClient default port allocation (#1409).
• Fix to the MqttClient and the allowed schemas in the connection URL (#1410).
• Removed unused or deprecated code. DrivePWM is no longer in the code. Use HardwarePWM instead. (#1423).

Automation

• Added automatic check for coding style rules
• Added automatic generation of chocolatey packages on new release (#1406).
