Release 2018-1 (23 Feb 2018)

Fixed bug when one tries a hydrograph with a steady model
Changed default underrelaxation to 1.0 from 0.9 (converges quicker for most simple models)
Fixed bug in check of line boundary condition for 3rd type boundary
Made it so if there are left/right errors with line boundaries, plots can still be drawn. Allows plotting partially-built models.
Re-coded digitize ellipse algorithm so it is more accurate and spreads points more efficiently using sin, cos functions
Re-do how starting radius is chosen for well pathlines, so start points are always just 1.2x well radius. With earlier algorithm, start points were at a radius 1.2x the larger of the pathline step size or the well radius. This sometimes resulted in pathlines starting at fairly large radii.
Add error message when a transient model has no spatially-variable area sinks (SVAS).
Changed sign of river discharges in line boundary condition check, so it’s negative for extraction out of domain, positive for injection into domain, consistent with the convention for other line boundaries and wells.
Changed sign of drain discharges in line boundary condition check, so it’s positive for flow from the start to the end of the drain.
Made it so pressing Edit and Coordinates buttons in input tables registers the row and proceeds, in cases where at least one other field of data has been entered. This used to always generate an error message. Now the error message occurs only if no data has been entered in the row before pressing the button.
Updated CAD drawing component. It now supports DWG 2018 format, among other improvements and bug fixes.
Built in warning message if license is within 10 days of expiry.
In plots of transient line conditions, added line label to the title of the window.
Plots can now display Analysis Inputs: hydrograph points, transient lines, graph conditions on line on plots. These all are in a separate layer of the drawing and can be turned on/off, change color, etc with View Manager.
