Check the revision history for all versions of MI-SDM, including this latest release

Improved in v2.51

Grid Shade (Grid Analysis module)	Improved options for colouring classified and continuous grids, with support for clipping, transparent classes and colour look-up tables.
Classify Continuous Grid (Data Preparation module)	Improved to Save and Read class definitions, and enter class breaks as percent values.
Extract Areas (Data Visualization module)	Option to specify threshold values as percent values.

Clip to Study Area (Data Preparation module)	Set output table name prefix or suffix for all layers to be clipped.
Contact Extractor (Data Preparation module)	Option to extract single-sided contacts.

New Features in v2.50

Edge Detection (Grid Analysis module)	Detect edges as polylines for grids and rasters
Statistics for Vector Layers (Statistics module)	Calculate univariate statistics for multiple columns in a table. Statistics can be grouped by attribute values and each column can also be displayed as a histogram.
Data Normalizer (Statistics module)	Normalize data by percentile or z-score, with levelling and log transform options.
Centrographic Statistics (Statistics module)	Spatial statistics for point layers
Bends, Jogs amd Splays (Data Preparation module)	Identification of splays added. Identification of jogs within lines added.
Neural Networks (Neural Networks module)	New Neural Network application GeoExplore replaces previous DataXplore. Supervized Neural Networks method now permits fuzzy membership values to be used for training points and for class weights. New supervized Probabilistic Neural Network method.

Improved in v2.50

Define Fuzzy Membership (Fuzzy Logic module)	Improved interface for defining fuzzy membership values.
Fuzzification (Fuzzy Logic module)	Improved interface and additional fuzzification functions. Graph now shows fuzzification function with data histogram. Continuous grids can be fuzzified. Fuzzification can be fitted to log transformed data.
Reclassify Layers (Data Preparation module)	Improved interface.
Aggregate Point Statistics to Polygons (Statistics module)	Optional prefix and suffix for new column names added by this routine.
Neighbourhood Statistics (Grid Analysis module)	Generalize option for classified grids, to remove small polygon areas without altering polygon boundaries.
Grid Calculator (Grid Analysis module)	New functions for sum, number of non-null inputs, and new literals for row, col, E and N.
Raster Classifiers (Data Preparation module)	Classify area of raster within selected polygon, allows classification to proceed with images that would otherwise be too large.
Project Explorer	Table info and metadata viewer available for all project layers. Modify Project option available from Project Explorer dialog.
