Possibility to show more noise values
The following noise values can now be shown after calculation:

Lday, Levening, Lnight, Lequ, Lmax, Lden and LmaxNight

Noise contour lines can also be produced for any of these values.

Freetext names for roads
Naming of roads/railroads can be used by giving freetext names, not only the norwegian road reference system.

Easier selection of roads/railroads
There is now an extra field for setting a line as road/railroad in the dialog “New road/railroad”.

Adding values for roads/railroads
It is now possible to add together calculations for roads and railroads done in one calculation.

Coordinates are given in East/North instead of XY
All coordinate namings are changed from XY to East/North.

Possible to select period lengths
According to directive 2002-49-EC, the national authorities can specify different period lengths for day/evening/night than the default value of 12/4/8. All the allowed variations can now be selected, in addition to a possibility to select calculation for only 2 periods: day (16h)/night (8h).

New help system
All help is updated and is available through http://wikinova.info. This will now be the only users manuals and help system.

Crash when opening drawing
Some user have had problems with the program crashing when calling the first noise function after opening specific drawings. This error is corrected.

“Profiling error” when calculating with reflections
When there are buildings with distance 0m from each other, one can get a “Profiling error” when calculating with reflections. This error is corrected.

Increased number of points in terrain profile
So far there has been a limit of 1200 points in one terrain profile before getting a “Profiling error”. This limit is now increased to 2400 points, since this can be necessary when calculating in dense triangle models.

Missing points at facades
After creating facade points for buildings, one facade of the buildings could be missing a facade point. This error is corrected.
