2.2.0

Breaking Changes

• empty groups and arrays are now always enabled instead of disabled and therefore errors can now be set on empty groups and arrays (note that this is only a minor breaking change and only applies in edge cases and therefore this fix is included in a new minor instead of a new major version) (749c1b5), closes #37

• fix createFormGroupState producing results inconsistent with how group states are recomputed from their children after an update (1c62d8c)
• fix createFormArrayState producing results inconsistent with how array states are recomputed from their children after an update (70fdc10)
