-- This release mainly addresses the breaking changes in the `netaddr` library.
-- With the new release of `netaddr` 1.0.0, the `IPAddress.is_private()` method has been removed and instead, the `IPAddress.is_global()` method has been extended to support the same functionality. This change has been reflected in the `ipaddr` filter plugin.
-- Bumping `netaddr` to `>=0.10.1`, means that starting from this release, the minimum `netaddr` version this collection requires is `>=0.10.1`.
