* Important: When you are updating to this version please ensure that you reconnect your Square account.
* New: Square's API has undergone significant updates and this update brings it up to date with all those changes. Specific updates include updating oAuth API to version 2.0, Locations API updated to v2, payment processing now using the new Payments API, and improvements to token renewals.
* New: Square now has a proper sandbox for testing so we have added a new "Connect to Square Sandbox" button within the admin.
* New: There is now a "Token Refresh" date field that displays within Square's WP-admin settings screen so you can more easily tell when the last refresh was and can even manually refresh it yourself. As well, there is also a line item under System Information for support.
