Compare Source

This is a non-functional release intended to refresh the codebase and dependency tree. There are no changes to the library's API or behaviour.

Breaking changes since 5.2.1

• Dropped support for Node versions less than v12.20

Misc other improvements

• The package is now a native ES6 module while still maintaining support for CommonJS
• All dependencies updated to their latest version

Upgrade Notes

• If you're using Node v12.20 or above it's safe to upgrade with zero changes to your code.
• Users of older versions of Node should stick with command-line-args v5.2.1.
