Release Notes

spf13/cobra

### [`v1.6.1`](https://togithub.com/spf13/cobra/releases/tag/v1.6.1) [Compare Source](https://togithub.com/spf13/cobra/compare/v1.6.0...v1.6.1) ##### Bug fixes 🐛 - Fixes a panic when `AddGroup` isn't called before `AddCommand(my-sub-command)` is executed. This can happen within more complex cobra file structures that have many different `init`s to be executed. Now, the check for groups has been moved to `ExecuteC` and provides more flexibility when working with grouped commands - [@​marckhouzam](https://togithub.com/marckhouzam) (and shout out to [@​aawsome](https://togithub.com/aawsome), [@​andig](https://togithub.com/andig) and [@​KINGSABRI](https://togithub.com/KINGSABRI) for a deep investigation into this! 👏🏼)
