Since Rob has committed his precipitation spatial interpolation, the 2D_interpolation reference result had to be updated. Several members in filter classes could be made const/static/private.

The median computations were relying on std::nth_element and wrongly assuming that the output would be sorted. This is non-standard behavior and is not the case with more recent versions of the STL. This has been fixed.

The ProcessingStack constructor has been optimized by using new methods of Config to remove some now redundant code.

In order to implement an efficient and portable object serialization, it has been decided that all serializable objects would be manually serialized to an std::iostream. Then, the parallelization framework (mpi, popc, etc) can take over this stream and move it to another node. Therefore, the operators "<<" and ">>" are now reserved for serialization (as seems to be standard) and the debug outputs are obtained by printing "object.toString()". This means that all debug code has potentially to be fixed, by replacing "std::cout << object" by "std::cout << object.toString()".

The full support for timezones has been brought back. This fixes issue 71. The SMET, SMET, IMIS, BORMA plugins have been validated. Geotop should be validtaed if an input data set is available. A new class will have to be implemented to represent time periods. This is currently only a typedef pointing to the Date class, but a specific class would be welcomed.

GSN has been fixed for some changes on the web service, but does not retrieve the correct timestamps (is this a GSN issue?). The GSN compilation has been improved: the warnings related to GSOAP have been removed. 

A new long wave radiaiton model using cloudiness as input has been added (Omstedt, 1990). 

The min and max filters have been implemented. The "how to write a filter" documentation page has been updated to relfect the latest changes. The operator << has been implemented for various objects involved in the data processing.

New filter system rolled out with currently two filters up and running: min_max and mean_avg (without the soft option, only left or right centering). The new filter system is built upon processing blocks that take a vector<MeteoData> as input and return a processed vector<MeteoData>. The individual filters are stacked in a ProcessingStack where they are invoked sequentially.

Introducing the new IOManager - the user interface to meteoio. This version is fully backwards compatible, but does not incorporate all features of the BufferedIOHandler: the grid reading and writing are currently not supported by this IOManager.

The unnecessary copies of a Config object have been removed from MeteoFilter and MeteoProcessor. Now, cfg is used in the constructor and not kept any longer. Next task: do the same for Meteo1DInterpolator!

The smoothing algorithms have been renammed as Process instead of Filter. The rate and the Tukey filters have been improved so that they correctly handles nodata.

A new resampling algorithm has been introduced: "none". It does just that: nothing. This is an easy way to debug filters by not performing any temporal interpolations.

The getMedian method has been re-implemented using the standard nth_element method for increased performances.

The doxygen documentation has been updated to reflect the latest changes.

MeteoData now has an extra public member variable: StationData meta. It will hold the meta information of the measurment instead of dragging along a second vector<StationData> alongside the vector<MeteoData> everywhere.

This has huge implications: the IOInterface has been rewritten, subsequently changes need to be propagated into all plugins and all modules dealing with meta data.

More debugging help: the "<<" operator has been redefined for MeteoFilter, MeteoProcessor and BufferedIOHandler. Since the Config object is copied all over the place, it is not always printed.

Fixed the behavior of ConfigReader when throwing exceptions: it rethrows so that the error message can be turned off by the receiver of the exception (if simply not printing e.what() when catching the exception). 

The warnings in FilterAlgorithms have been turned off cast to void) since this is an algorithm that has to be re-written anyway. The documentation has been fixed (missing documentation, broken link, etc)

The new filtering and resampling framework. Filtering/Processing and Resampling have been separated from each other, the Resampling is now done with the class Meteo1DInterpolator which utilizes the static algorithms within ResamplingAlgorithms. The filtering remains a task of class MeteoFilter. The calling of the resampling and filtering as well as the data selection is now based in the facade class MeteoProcessor. MeteoProcessor::processData function calls the filtering algorithms, then passes the filtered data to the resampling algorithms and finally runs a "check only" filtering pass.

The filtering system underwent some changes in order to simplify the tasks at hand, the interface has changed.

The RateFilter is currently disfunctional, needs to be reimplemented.
