+`matplotlib.ticker.LogLocator` gains numticks kwarg
+---------------------------------------------------
+
+The maximum number of ticks generated by the
+`~matplotlib.ticker.LogLocator` can now be controlled explicitly
+via setting the new 'numticks' kwarg to an integer.  By default
+the kwarg is None which internally sets it to the 'auto' string,
+triggering a new algorithm for adjusting the maximum according
+to the axis length relative to the ticklabel font size.

+For a log-scaled axis the default locator is the
+`~matplotlib.ticker.LogLocator`.  Previously the maximum number
+of ticks was set to 15, and could not be changed. Now there is a
+`numticks` kwarg for setting the maximum to any integer value,
+to the string 'auto', or to its default value of None which is
+equivalent to 'auto'.  With the 'auto' setting the maximum number
+will be no larger than 9, and will be reduced depending on the
+length of the axis in units of the tick font size.  As in the
+case of the AutoLocator, the heuristic algorithm reduces the
+incidence of overlapping tick labels but does not prevent it.
