concurrently 10.0.0 on Node.js Yarn

💥 Breaking Changes

Dropped support for Node.js <22.0.0.
Older Node.js version have reached end-of-life, and certain features require new-ish JS APIs.
concurrently is now ESM-only.
It's now possible to require(esm). See here for interoperability.
Prefix colors now default to automatic - #581
The colors used to default to reset (which does nothing). Concurrently now automatically selects a color, out of the box.
The list of colors used is not jarring nor carries semantic meaning, and reads well in both dark and light terminal backgrounds.
Removed deprecated flags and options
- CLI flag --name-separator: use commas instead.
- API option killOthers: use killOthersOn instead.

Support applying modifiers to hex prefix colors (e.g. #ff0000.bold) - #450
Support chalk's color functions in prefixes (e.g. rgb(), hex(), bgRgb(), etc) - #578
Set prefix background color via bg#RRGGBB - #578
Allow shell override via --shell CLI flag/shell API option - #288, #589, #556
concurrently distinguishes between cmd.exe, powershell, and POSIX-based shells.
Manual prefix coloring in templates e.g. [{color}{name}{/color}] - #583, #587

Scope quote normalization to CLI input - #582, #585
It should now also be possible to run commands like "/some/command" foo bar"
Don't throw when color doesn't exist - #580
