Monetra 8.11.1 has been released and is available for upgrade. This release contains no security fixes, but it does contain an update that is necessary for First Data (Datawire) customers in order to maintain functionality.
If you are a First Data customer, and have not updated to this release before Datawire releases their fix (the fix release date has not yet been announced), you will no longer be able to process credit cards until you update to Monetra version 8.11.1 or newer.
