 HISTORY:
+1.11: usability + bug fixes.
+- new feature: "hide obscured x ticks=false" to disable the feature which hides ticks
+- simplified UI for symbolic coords: now, it accepts unexpandable
+  dictionary entries including umlauts, undefined macros, math mode, ...
+- simplified UI for symbolic coords: added magic prefix 
+	[normalized]<number> to allow something like xmin={[normalized]0.7}
+- simplified UI for custom annotations: one does not need to say "axis cs" any longer;
+  coordinates like (1,2) are now automatically interpreted as (axis cs:1,2)
+- new feature: 'type ticklabels with struts' improves baseline alignment of tick labels
+- new feature: 'trig format plots=rad' allows to use radians in trigonometric evaluations
+- simplified 'external lib': added driver auto-detection for pdflatex, lualatex, xelatex, dvips
+	(\usepgfplotslibrary{external}, or, with the next PGF release, \usetikzlibrary{external})
+- simplified UI for \addplot coordinates: now, it expands macros as it goes.
+- new feature: 'intersection segments' now accepts negative indices to count from the last backwards
+- simplified UI: 'intersection segments' now accepts new syntax with 1-based indices (old 0-based are still supported)
+- fixed bug: fillbetween has had a problem with pins on input paths
+- fixed bug: now, 'stacked ignores zero' is no longer applied to error bars.
+- fixed bug: tick lines were drawn incorrectly for centered axis lines in 3d
+- fixed bug: variable=u failed to work in some contexts
+- fixed bug: fill between implicitly activated layers, but did not install the
+   correct layers for grid lines etc.
+- fixed bug: z grid style was applied to y grid style
+- fixed bug: using 'x=1cm' failed to work in axis descriptions (legends)
+- fixed bug: mesh legend failed to work with 'shader=interp'
+- fixed bug: bounding box of shader=interp was wrong if there were transformations.
+- fixed bug: added support for \addplot graphics in ConTeXt
+- fixed bug: external lib failed to work with dvips (since PGF 3.0.0 I suppose); now it produces correct bounding boxes
+- fixed bug: \pgfplotstablenew can now overwrite existing tables.
+- fixed bug: extra ticks near intersections of axis lines were hidden
+- fixed bug: 'intersection segments' did not work with '--cycle'
+- fixed bug: 'intersection segments' did not update the last tikz point
+- fixed bug: tick lines/grid lines have been clipped when they were near the boundary
+- fixed bug: soft clip decoration failed to apply the transformation matrix
+- fixed bug: polar axes and units library resulted in broken bounding box
+- fixed bug: \addplot[stack plots=false] used to work up to 1.8, but failed until now. Fixed.
+- fixed bug: hist/density was broken since some time
+
+
 1.10:
 - new feature: fill between plots (library fillbetween)
 - new feature: concatenate intersection segments (library fillbetween)
