Change log

IGA forecast deprecated, 2021-11-16

The IGA text forecasts will terminate on 2022-03-01, to be replaced with graphical forecasts in the Routeforecast product (route=iga-XXXX-YYYY).

aviation text forecasts moved to separate product, 2019-04-24

Since textforecast version 1.6 is deprecated and will be removed soon, we have moved the aerodrome and IGA forecasts to a separate product. This will enable them to keep stable while the other text forecasts are in the process of being updated to 2.0 standard.

aw_enry replaced by aw_ento, 2019-02-01

Rygge airport is currently closed, so no ENRY forecasts have been issued this year. Instead we are now producing aerodrome forecasts for Torp (ENTO). iga_fbno43 has also not been in production for a long time and has been removed.

several forecast types removed, 2019-02-01

On February 1st, 2019 we will remove the route_fbno* products. These will be replaced with the new routeforecast service for automatically generated graphical forecast. The old route_fbno forecasts will be available on NAIS for some time.
