user v0.3.0 - remove userns package that was added in v0.2.0 - downgrade minimum go version to v1.17 - retract v0.2.0 Breaking changes: This release removes the userns package, which was added in v0.2.0, and now retracted. Commit 86870e7b5ae771ec567bf0519663b95345ba59e3 integrated the userns package into the github.com/moby/sys/user module, which was included in the v0.2.0 version of the module. After further discussion with maintainers, this was not a good choice, as the package has no direct relation with "user" operations (other than their name). For that reason, the userns package was move to its own module and can now be found in the github.com/moby/sys/userns module. This release retracts the previous (v0.2.0) release and removes the userns package, effectively reverting the module to v0.1.0.
