1.2.1

----------
2023-09-28

This version implements CAAML export with grain shape estimation via machine
learning as well as some convenient new user interface features.

- Added CAAML export: export of SMP forces and derived values for density,
specific surface area, grain shape, grain size and hand hardness. The
resulting CAAML file is readable by niViz and SNOWPACK.
- Added machine learning interface: snowmicropyn can now be trained on snow pit
test data to assimilate estimated grain shapes into the CAAML output.
This includes modules for training data generation (profile matching),
data preprocessing, scoring, training, and saving/loading trained model
states (albeit all in an early state of development at this point).
- Added new export window: The CAAML export including the machine learning
model fitting can be controlled almost fully in the GUI (in addition to a
comprehensive developer's API). Also, some meta data that is not recorded
by the SMP can be included.
- Added schema validation for produced CAAML files according to IACS standards.
- Added extensive example program for our machine learning API.
- The air gap (before the SMP probe hits the snow surface) can now be hidden in
the plots (single ones and superposition) for easier comparison.
- Added quality control panel. Several flags and comments can now be saved to
the profiles' ini files.
- Custom taskbar icon.
- Several minor UI improvements.
- Fixed bug preventing the setting of markers on some systems.
- Several minor bugfixes.
- Added download tool for a subset of the RHOSSA dataset for easy access to
public (training) data.
- Improvements to the framework.
- Documentation improvements.

1.1.0

-------------

2022-02-11

This version brings a thorough refactoring in order to offer a clean
interface for implementing new parameterizations (density, SSA) by lifting
the burden of having to deal with the GUI (everything is automatic now).
Three new parameterizations were added (Calonne/Richter and King x2), as well
as an export tool for niViz visualizations. The documentation was overhauled
and a few bugs and usability issues were fixed.

- Added Calonne/Richter parameterizations for density and SSA
- Added King parameterizations for densities
- Added export tool for visualization with niViz
- Changed Proksch SSA units to m^2/kg
- Removed GUI options for window_size and overlap: these are now
constant per individual parameterization untangling much confusion
about the display resolution
- Added setting to output any of the available parameterizations
- Much improved interface for adding new parameterizations
(all GUI stuff is handled on the fly and the required code was minimized)
- Added setting to skip samples output
- Added unit test for core parameterization routines
- Export menu now exports all open profiles
- Bugfix for constant signals
- Fix crash on program exit
- Bugfix for linefeeds
- Bugfix for overlap factor
- Minor bugfixes
- Documentation fixes and enhancements
- New documentation chapters and examples
