The 1.5.7 Plugin update follows on from the last Plugin update adding filters to allow third-party payment option support as well as overhauled validation at Checkout.
The big changes in this Plugin update are in the templating department, web developers can now copy the OCCP template files from /templates/ to their WordPress theme directory just like in other Plugins; this will be extended further in the next Plugin update to allow easy template support for the Checkout payment option which is not yet supported. Also joining the Settings page is a set of labels to manage the Card Type, Card Name, Card Number, Card Expiry and Card CVV, all of these fields can be renamed at any time within the WordPress Administration (e.g. Card Expiry to Valid Through).
As always, download your Plugin update from Premium Plugin Updates or jump over to the Plugin detail page for more information.
