v0.38.1

Fixed

• Upgrading could create a duplicate Condition attribute (#649).
  • Two copies of Condition could appear under Products then Attributes, depending on how busy your store was during the upgrade.
  • Upgrading to this version removes the extra copy automatically and keeps your values.
  • Don't delete a duplicate yourself from Products then Attributes. WooCommerce removes every value in the attribute when you do that, which empties the copy you keep.
