3.1.0	2024-02-18	Added the odds ratio and related statistics to the contingency table dialog. Enabled numeric thresholds to be specified as an upper limit instead of just a lower limit for contingency tables and ROC curves. Added some statistical method references to the documentation.
3.0.0	2024-02-12	Attributions are now required for alternate basemap tile servers. This is a BACKWARDS-INCOMPATIBLE change for users of alternate basemap sources. Stamen maps are no longer included in the built-in set of tile servers because they now require an API key to access via Stadia Maps. Enabled Control-click to de-select a map marker. Added calculation of contingency tables and related statistics. Added calculation of a Receiver Operating Characteristic curve and statistics. Added command-line arguments to import data from a database. Enabled setting of command-line-equivalent arguments in configuration files.

Added a menu item and dialog to select data based on locations with a specified number of co-located data rows. Enabled right-click on a map location marker to display a list of identifiers, with counts, at the location. Added more non-overlapping symbols. Added the ‘Table/Counts by location’ menu item to display the number of data rows for each unique geographic coordinate. Enabled Alt-C to toggle display of the count of data rows at each map location. Added the Mann-Kendall Trend Test to the bivariate statistics summary. Enabled alpha adjustment on the Normal Q-Q plot. Enabled use of a grouping variable with histograms, to produce stacked plots. Enabled flipping of the Y axis on min-max and Y-range plots. Enabled Alt-G to open a new plot dialog from the main application. Enabled axis rotation for the category counts plot. Added sum to the univariate statistics summary. Added plots of totals and means by category, and min-max by bins. Improved querying of numeric columns so casts are no longer necessary. Enabled numeric sorting of the data table. Added the ‘read_config’ configuration file setting. Added Load, Save, and Edit functionality to the data query dialog.
