Spring 2022 Release 🌥️

Hello everyone! Welcome to another release of cobra. Completions continue to get better and better. This release adds a few really cool new features. We also continue to patch versions of our dependencies as they become available via dependabot. Happy coding!

Active help 👐🏼

Shout out to @marckhouzam for a big value add: Active Help #1482. With active help, a program can provide some inline warnings or hints for users as they hit tab. Now, your CLIs can be even more intuitive to use!

Currently active help is only supported for bash V2 and zsh. Marc wrote a whole guide on how to do this, so make sure to give it a good read to learn how you can add this to your cobra code! https://github.com/spf13/cobra/blob/master/active_help.md

Group flags 🧑🏼‍🤝‍🧑🏼

Cobra now has the ability to mark flags as required or exclusive as a group. Shout out to our newest maintainer @johnSchnake for this! #1654 Let's say you have a username flag that MUST be partnered with a password flag. Well, now, you can enforce those as being required together: 

rootCmd.Flags().StringVarP(&u, "username", "u", "", "Username (required if password is set)")
rootCmd.Flags().StringVarP(&pw, "password", "p", "", "Password (required if username is set)")
rootCmd.MarkFlagsRequiredTogether("username", "password")

Flags may also be marked as "mutally exclusive" with the MarkFlagsMutuallyExclusive(string, string ... ) command API. Refer to our user guide documentation for further info!
