Since the IIR filter implementation can do both High and Low pass, it has been renamed to IIR and options have been added to use it as either low or high pass filter. The documentation has been improved and stability constraints now lead to a warning message if the filter would start to be unstable.

The Butterworth filter has been replaced by a critically damped filter implemented as IIRLowPass that properly corrects for the phase (ie behaves as zero-phase filter).

A small bug has been fixed in the SMET specs. The experimental "UnShade" filter has been removed while the SNOS filter has been renamed as "DETECT_GRASS" and MAX_CHANGE as "Time_Consistency" in order to better reflect the cited paper. The NOISE processing is now documented. Otherwise, some documentation typos have been fixed.

The new AGGREGATE filter has been tested and now replaces the other, multiple filters that used to do similar aggregation.

A new method has been implemented in order to apply a horizon mask to ISWR. This has not been properly tested yet, this will come soon!

Changing some invalid execute properties and adding a new processing: AGGREGATE. This should replace several of the existing filters as well as bring new features

This is the first implementation of the algorithms described in Tilg, A.-M., Marty C. and G. Klein, 2015: An automatic algorithm for validating snow depth measurements of IMIS stations. Swiss Geoscience Meeting 2015

Finally, a long awaited (and MAJOR) change: HNW is gone, it is now PSUM. This name should be clearer and every occurences of "HNW" (even in temporary variables or algorithms) have been replaced by psum. A check is performed on keys containing "hnw" and an exception is thrown if some are found, urging the user to update the ini file. Please keep in mind that the calling codes have to now refer to MeteoData::PSUM and that some algorithms are now named differently!

A new "NOISE" filter has been added, to add noise to the inputs. An improved check and error message has been implemented in FilterSuppr. An updated reference added to the ESOLIP generator.

better file structure: all the classes purely focused on data storage (such as grids, dates, etc) have been moved into a "dataClasses" directory. All subdirectories are nhow named similarly to the classes and methods: the words after the first one are capitalized.
