The NWP SAF follows a programme of continuous development with periodic releases of deliverables. The programme is periodically reviewed to reflect evolving user requirements. Each year detailed plans are defined for the year ahead, together with outline plans for the remaining period of the SAF. For information on the latest developments see the news page.

Users must agree to the NWP SAF Licence Agreement before downloading the software.
