The Spanish Overlay for Dynamics SL 2015 CU1 is now available for download here.
This is an updated version of the 2015 Spanish Overlay that was released in December. Included in this updated version are fixes for reported issues, as well as the first release of a Spanish version of Web Apps. This Spanish version of Web Apps is only intended for 2015 CU1.
Note: The rich client (non-Web Apps) parts of the overlay work with SL 2015 or 2015 CU1.
