* NT-MDT: Fixed loading of old spectroscopy from Nanoeducator2 data. Search of external data in another possible location is implemented.
* Pygwy: It is possible to write volume data processing modules in Python. Brick has a duplicate() method, gwy_app_data_browser_get_current() supports brick-related items. Python error messages are no longer silenced after Python modules are run.
* Color range tool: The range can be set to the range of masked/unmasked values.
* HDR image: NaNs and infinites in floating point images are removed and masked upon import.
* Slope distribution: A bad typecast causing Gtk+ warning was fixed.
* Sat Jun 28 2014 arunAATTgmx.de- updated to version 2.37 Application
* Translations updated: Czech, French, Italian, Russian. Libraries
* libgwyprocess: A function for filling grain voids was added.
* libgwyprocess: A simple x and y derivative filter function was added.
* libgwyprocess: A regional extrema marking function was added.
* libgwyprocess: A classic Vincent watershed algorithm function was added.
* libgwydgets: Several new stock icons were added.
* libgwyprocess: Pixel count was added as a new grain quantity.
* libgwyprocess: Crash in gwy_grain_values_calculate() when a quantity was requested multiple times was fixed.
* libgwyprocess: New function for performing one step of facet levelling.
* libgwyddion: New data type GwyRandGenSet providing a convenient set of random number generators and functions for sampling from different distributions.
* libgwyprocess: DataField z-value format is now based on autorange instead of the full data range.
* libgwyddion: Environment variables such as GWYDDION_LIBDIR override the system-default paths on all systems, including OS X now.
* libgwyddion: Module and data paths on OS X are taken from the bundle \"net.gwyddion\" instead of the main bundle, fixing broken paths in the standalone Python gwy module. Modules
* WinSTM (new): Import WinSTM data files.
* Mark by Segmentation (new): Another segmentation/grain marking module, based on the classic Vincent algorithm.
* Grain filter (new): Filtering of grains by range criteria and logical expressions.
* Slope statistics (new): Statistics were split off Slope distributions, the GUI and functionality is the same as before.
* Lattice synthesis (new): Construction of surfaces based on Voronoi tesselation of randomized lattices.
* Grain removal by threshold: Removed. Threshold-based removal is replaced by Grain filter (also replacing it the default toolbox). Removal of grains touching image edges is a standalone menu function now.
* Mask operations: Function for removal of grains touching image edges was added.
* Mask editor tool: Fill voids handles correctly different connectivity of grain exterior, noticeable for grains separated only by thin lines. It is also possible to fill only simple-connected grains.
* Pixmap: Vertical and horizontal rulers always use the same number format. The gap between image and false colour map can be adjusted, as well as the gap beteween the inset scale bar and image border. Missing lower left corner of the false colour map scale border was fixed. Text antialising can be disabled.
* Affine distortion: The ACF image can be zoomed.
* NT-MDT: Double inversion of new spectroscopy data properly checked and fixed.
* Slope distribution: Masking is supported. Plot of total gradient was added.
* NanoScan: A couple of memory-hadling bugs was fixed.
* Grain distributions: Displays a preview graph of the selected quantity.
* Grain correlations: If run interactively and the same-units condition of selected quantities is not satisfied, default quantities are selected instead of aborting with an error box.
* Slope distributions: Preview of the result was added.
* Dimensions and Units: False colour axis actually starts showing the new value units also when you change only the units (not the Z range).
* 2D FFT Filter: FFT output centre of lateral coordinates is at the zero frequency now.
* 2D FFT and FFT profile: Slight offset of lateral coordinates for odd-sized images was corrected.
* Spectral synthesis: Critical message/crash, occuring when some files were loaded but no channel was active while invoking the function, was fixed.
* Cross-correlation: now allowing use of multiple channesl and output of all the results together. Other
* The standalone Python gwy module uses the correct extension for dlopening, fixing the failure to load Gwyddion libraries on OS X.
