We recommends to not update WooCommerce version upper than 2.5.5 before we release compatible version of latest WooCommerce update.
If you have updated, don't worry for that notification. We have begin working to change the files that are outdated and apply the changes that are made on the WC 2.6, we don't have any exact time when the update should come but when the update it's ready you will receive an email if you have enabled "Get notified by email if this item is updated" from your Downloads tab, then you can update your theme through Envato Market or Envato Toolkit plugin.
When will Kalium be compatible with WooCommerce version 2.6?
