NEW FEATURES

Kaiser Optical Systems HoloReact method importer to create preprocessing from band-area methods (hrmethodreadr).
GLSW/EPO: add "meancenter" option to better handle orthogonalization to specific clutter matrix, plus improved help (glsw).
Improved memory and speed performance for various preprocessing methods.

KNN Score Distance metric available in scores plots of PLS, PCR, and PCA (knnscoredistance).
Improved handling of class modifications.

Selectivity ratio (variable selection information) added as calculated statistic for PLS PCR and MLR models (sratio).

Direct Scores PLS (DSPLS) algorithm availabe in PLS (dspls).
Automatic correction of regression model bias and slope based on test data (correctbias). NOTE: PLS_Toolbox only - not yet available in Solo
Bias and R^2 information available for all steps of model building (calibration, cross-validation, validation)
Improved automatic component selection in PCA models.
Additional tests for poor choices of preprocessing with certain model types (e.g. CLS).
User information stored with each model (as history information).

Experiment File Importer - reads file containing filenames and reference measurement data and imports the corresponding files and data into Analysis GUI. Automatically assigns the data to X and Y and to calibration and validation blocks (experimentreadr).
Hamilton Sundstrand PIONIR PDF file importing (pdfreadr).
Improved Horiba JY file importer performance (hjyreadr).
Improved support for combining multiple DataSets. Selecting multiple items in Workspace Browser provides access to new "combine" menu option.
Improved XY file importing performance (xyreadr).
Improved XML importing/exporting support and performance (parsexml / encodexml).
Improved support for manual parsing of CSV files (xclreadr).
Export to Analect Spectral Files (ASF) (writeasf).
Export to simple CSV file format for non-DataSet objects (writecsv).

TrendTool: Improved interactivity.
Model Cache: Improved performance and support for new information in models and DataSets.
InfoBox: New File/Save menu option.
DataSet Object: Add ability to log user comments to history.
DataSet Object: Add uniqueID field and support.
