New Features

• Runs natively on Intel and Apple Silicon and supports retina displays
• Python 3 support (including a bundled 3.10 installation in the app)
• images can now be exported in HEIC format and videos support H.265 (HEVC)
• SVG files can be drawn to the canvas using the image() command (thanks to the magical SwiftDraw library)
• image exports have a configurable zoom to create 2x/3x/etc ‘retina’ images
• revamped var() command for creating GUIs to modify values via sliders, buttons, toggles, etc.
• updated text editor with multiple tabs, new themes, and additional key-binding modes emulating Sublime Text and VS Code
• the module's command line interface is now accessible through python3 -m plotdevice
• the command line tool has a new --install option to download PyPI packages for use within the app
• document autosaving is now user-configurable

Bugfixes

• exported images generated on retina machines now have the proper dimensions
• hex colors can now use lowercase letters
• automatic variables like WIDTH & HEIGHT correctly support the / operator
• the Color object's .blend() method is working again
• the read() command can now handle csv files with spaces in their header row names
• the translate() command now incorporates non-pixel grid units set via the size() command
• cmyk exports are working reliably for command line --export and via the export(cmyk=True) method
• arguments defined using the command line tool's --args options are now passed to the script's sys.argv

Misc. Improvements

• the command line tool can be exited via ctrl-c in addtion to being Quit from the menu bar
• simplified unicode handling (and improved support for normalization of user-provided strings)
• building the module now only requires Xcode command line tools—not a full Xcode.app installation
• the text() command will always treat its first argument as content (even if it's not a string) unless a str, xml, or src keyword argument is provided
• the mouse pointer is now visible in full-screen mode (and will auto-hide when inactive)

Unfortunate Casualties

• The NodeBox Libraries (coreimage, colors, and friends) would require quite a bit of attention to get working properly again.
  A first pass can be found in the plotdevice-libs repository but they're not
  ready for prime-time. If you're interested in contributing, this would be a terrific place to start!
