Mariani v1.6 (3) is released. Mariani is a native macOS UI for AppleWin, by way of Andrea's Raspberry Pi port.

Features:
Native, universal macOS UI
Screen recording
Copy screenshot to pasteboard
Disk image browser, including syntax-highlighted listings for Applesoft and Integer BASIC, as well as hex viewer for other file types
Floppy and hard disk image creation
Full-screen support
Debugger and memory viewer in separate windows

Mariani Changelog: Starting in the 1.6 (1) release, Mariani will sporadically check GitHub on launch to see if a new version is available. No personally-identifiable information is sent to GitHub but I expect some metadata like origin IP address might be logged by GitHub. You can disable this behavior in Settings.
Speculative fix for #84, a crash on start-up (or possibly when manually checking if a newer version is available)
