A new readDirectory() method has been implemented that directly returns a list of strings (slightly more convenient to use). An innacurracy has been fixed in IOUtils: lat_epsilon and lon_epsilon were defined in rad when they should have been in deg. The Coords::toString() method has been slightly improved by allowing more digits for lat/lon. The smet_extract.sh script can now provide a list of available fields if no field has been specified.

Some threshold were making trouble for very high resolution simulations with Winstral, they have been changed. A broken link has been fixed in NetCDFIO.

The Winstral interpolation was not behacing properly when dealing with a DEM with holes, this has been fixed. Otherwise, the grids initializations use some recently introduced API that makes the code easier to read.

An invalid C to K conversion was fixed (it used the water triple point temperature instead of melt/freeze). A much improved smet_extract that processes one file at a time has been committed. The config object now is much more verbose when reporting an invalid key and does not write out invalid key/values (basically, key with empty values). This makes it possible for example in Snowpack to re-run a simulation using the backed up ini file (without any changes).

Anselm koehler contributed these two Matlab scripts to read and plot SMET files, making use of all fields and metadata. 

Similarly to the "::EXCLUDE" statement, it is now possible to use a "::KEEP" statement. This makes it possible to keep only a few parameters from given stations.

Now multiple DEMS can be cached. The implemented solution is not fully satisfactory (a API change for all plugins would be required), but at least the core of it is implemented (in the Buffer class).

The GridBuffer class has been expanded and is now used by Meteo2Dinterpolator for interpolated grids

A gridBuffer class has finally been implemented (basically, moving the old grid buffering code into it) and is now in use for the GridsManager. An invalid file name in the examples has been fixed and a toString() debug message has been improved in the TimeSeriesManager.

When using Winstral with precipitation AND exclusively positive temperatures, the deposition mass was zero and was leading to an arithmetic error

When using Ordinary Kriging, the nodata cells where still computed... This has been fixed, they are now properly skipped.

Trying to make the documentation more user-friendly. The smet2agr script has been modernized (changing the syntax of a regular expression).

A new plugin has been contributed to acces the SASE Mysql database (obviously, this only makes sense from within SASE).

The LIDW algorithm has been restructured in order to look more similar to IDW. It is still quite special, though.

It is now possible to write timestamps as ISO_WEEK (this is YYYY-Www-dd). This is now used for the reports generated by DATA_QA in order to ease data aggregation. The GSN plugin has a new key: GSN_TIMEOUT. A bug in error handling was fixed in the GSN plugin.

The Date class can now compute the dow of week as well as the ISO week number. Fixed a documentation typo in FindMySQL.cmake

The Buffer class is now used to buffer meteo time series. Since this is not (yet) a proper ringbuffer, all data is erased before pushing more data into a buffer (similarly to what it was before this commit). It has been tested with data_converter on numerous data (including with virtual stations) as well as with snowpack on operational stations.

The units conversionm now work for 'simple' units, with prefix and exponents. 'Composite' units (such as 'K/m' or 'N/m2') are currently not supported.

The virtual stations have been re-enabled. A new generator has been implemented to generate ISWR from RSWR or the opposite. Some documentation has been improved. The Black Globe Temperature index should now work.

The CH1903+ coordinate system has been implemented. in GSNIO, setting the station name was not always properly done. The ADD and MULT filters now offer a better parsing of their arguments in order to avoid silently failing; their documentation has been improved. When compiling with DATA_QA, parameters that are filtered but have no value (nodata) are now reported.

the GSN plugin now has a "GSN_DEBUG" key to print out the full dialog with the server in case of errors. Some headers returned by GSN did not follow what we expected (multi-lines description) and this is now supported. New sensors names are also supported so the Stillberg data can be read.

The buffers have to extra setters to manually set the start/end dates (this is quite a hack but will be required for the first implementations relying on them).

Finally adressing issue 72 with second resolution in dates. The ISO strings now contain the seconds when written out and by reading them, the seconds can be provided (but this is not mandatory). In ARC, grids are now named with the seconds (except when enabling the Alpine3D naming scheme). The adresses a bug that was found when requesting" raw" processing level from a plugin that constructs its timestamps from a decomposed time: time-1s and time+1s were the same and therefore this could trigger problems in the plugin.

Slightly improved toString() output as well as first version of a proper Buffer class (not used yet)

One of the last commits was just wrong: adding a boolean and a string should not be possible! This has been fixed.

The POT_RADIATION generator has been renamed as ALLSKY_SW for consistency and its documentation updated. The ALLSKY_LW generator's documentation has also been updated.

A getHash() method has been added to the StationData. It is currently quite unsophisticated but should do the job. A better error message has been found for the "frac" lapse rates that can lead to a zero lapse rate (this is the case when there is no precipitation, for example). 

Better information message when forcing a null lapse rate on a linear regression (this happens when using "frac" on precipitation for all timesteps without precip)

Following a bug report from GeoTop, the add_to_cache() method that had been partially removed is now back, under a slightly different name: add_to_points_cache(). Otherwise, white spaces, copyright headings were modified and some pragmas added for VC++ in GSNIO and CosmoXMLIO.

Some fixes to make MeteoIO compile with Visual C++ 2013. The linker still complains about exported symbols (this also generate lots of warnings), but all the other issues have been fixed.

Add the possibility to delete keys based on string match (from the begining or anywhere in the key). This is useful for example to remove all stations declared from the user in the ini file.

After talking with the GSN team, the GSN plugin has been fixed and works again. It has been simplified according to their recommendations (ie that the metadata is always delivered with the data). We should still implement arbitrary units handling (parsing the strings and converting to SI).
