The word wrapping will have changed in the release notes, prettier needs to run.

yarn lint:fix responds "Invalid option '--write' - perhaps you meant '--rule'?". Removing --write, yarn lint:fix replies "No files matching the pattern "prettier" were found.". yarn lint responds [error] "No files matching the pattern were found: "'**/*.{js,jsx,ts,tsx,graphql,md,json}'"". I'm on Windows.

Ah on windows you can’t have single quotes in shell args. Not sure about—write though, works for me and is documented. Thanks for trying.

Oh, again it’s the semicolon which doesn’t work for Windows.
