What is new in Dimmerly 1.4.2

# Dimmerly 1.4.2

A small fix for the menu bar panel.

**Upgrading from before 1.2.0:** Existing Shortcuts with a specific display selected need that display reselected once after upgrading. Follow the [upgrade instructions](https://dimmerly.olujic.in.rs/support.html#shortcuts-upgrade). Upgrading from 1.2.0 or later does not require repeating this step.

### Fixed
- The menu bar panel grows with its content. Turning on Auto Warmth while the panel is open no longer pushes Settings… and Quit Dimmerly out of view.
