• Proper poll/listen handler setup in open_window(...).
• Cleaner poll/listen handler shutdown on ewwii close.
• api::linux for getting system information like cpu, gpu, ram, disk, kernel version etc.
• Support for defining multiple enter([..]) at top level.

Changed

• Changed std::monitor return values so that it will work fine with Rhai.

Removed

• Deprecated attribute warning which cluttered the logs.

• std::math (Rhai already convers everything that it has).
• The need for dyn_id for dynamic system. THIS IS A MAJOR UX change as it massivly reduces errors and the burden on users.
• Daemon exit on configuration error mechanism in favor of hot-reloading.

Added

• std::json module to handle all json related tasks in Rhai.
• api::wifi module for handling wifi related tasks.

• propagate_natural_height property to scroll widget.
• Faster re-evaluation of configuration by reusing compiled configuration.
• Improved runtime error handling of WidgetNode casting.
• Caching for ParseConfig in re-evaluation system.
• Proper error handling for runtime error in external module code.

• std::command module for running shell commands.
• INPUT_VAL environment variable for Input widget commands (onchange and onaccept), containing the current text of the input field.
• Parse error handling for external module code.
• Killing poll/listen handlers feature in ewwii kill command.

Changed
