<li>We introduced two new metrics for tail color and competitor chart: Change of Gap, and Change of Gap to Leader.
These represent an average of the respective gap value change over the last approximately five position fixes,
e.g., 5s for a 1Hz sampling rate.</li>
<li>When using tail colors to visualize metrics, so far we spread the value range across the colors available
in a "linear" way. This made outliers and maneuvers waste a lot of the color space. Instead, for all
metrics except over ground (COG) we now use a cubic root function that reserves most of
the available color space to the values in the middle of the range to be visualized, whereas
the values closer to the boundaries of the range are assigned less space of the color range.
See how the color key displayed at the top of the map changed.</li>
<li>Introduced a new metric for visualization in the competitor chart and as a tail color: percent
target boat speed. This is computed from the polar data and the local wind conditions (TWS, TWA)
at the position of the competitor at the given time point.</li>
<li>Hovering over a colored tail on the map where the color represents a detail value as selected by the user,
the tool tip that pops up will now display the detail value at the point over which the mouse pointer
is hovering.</li>
<li>Another fix to the polar data CSV export from the Data Mining module; the ";" separators were missing
for the negative (port tack) angles.</li>
