This took much more than I expected but finally, I'm glad to announce that a new major version of argparse is published.

This version contains a bunch of breaking changes as well as a bunch of enhancements and bug fixes. Most important is that it now follows POSIX convention for command line tools by default. This eliminates the surprises for users who expects certain behavior from UNIX tools.

Please see all changes that went into this version here

Thanks to everyone who helped me with this - you made it possible and much better!
