Changes:
1.12: scalability + performance
- scalability: reduced TeX memory consumption for huge inline tables
- scalability: lualatex allows bigger 3d graphics
- scalability: lualatex now reduces compilation time for huge 3d graphics
(requires \pgfplotsset{compat=newest} at the time of this writing)
surf shader=faceted: time reduced to 61% of pdflatex
(\addplot3[surf,samples=70] {exp(-x^2-y^2 +x*y)})
surf shader=interp: time reduced to 25% of pdflatex
(\addplot3[surf,shader=interp,samples=70] {exp(-x^2-y^2 +x*y)})
surf shader=interp, parametric: time reduced to 36% of pdflatex
(\addplot3[surf,shader=interp,z buffer=sort, samples=50,domain=-
1:0,y domain=0:2*pi] ({sqrt(1-x^2) * cos(deg(y))}, {sqrt( 1-x^2 ) * sin(deg(y))}
, x);)
surf shader=faceted, parametric: time reduced to 40% of pdflatex
(\addplot3[surf,z buffer=sort, samples=50,domain=-1:0,y domain=0
:2*pi] ({sqrt(1-x^2) * cos(deg(y))}, {sqrt( 1-x^2 ) * sin(deg(y))}, x);)
- scalability: lualated now reduces compilation time for boxplots.
10000 input points from table: time reduced to 23% of pdflatex
- fixed bug: 3d axes where all axes used log scale produced compile failure
- fixed bug: axis equal did not respect "disabledatascaling"
- fixed bug: mesh legend was confused by color input=explicit
- fixed bug: colorbar style did not reset zmin/zmax
- fixed bug: memory allocation in FPU consumed too much memory
- fixed bug: boxplots: removed compilation error due to spurious spaces in optio
ns list
- fixed bug: boxplots: now uses standard quantile estimators: has all 9 estimato
rs of R and uses the same as in Excel as default (as of compat=1.12)
- fixed bug: boxplots: sometimes failed to compute boxplot statistics for specia
l inputs
- fixed bug: boxplots: now, it sets 'mark=*' for outliers if there is no mark (c
ompat=1.12)
- fixed regression: compat=1.11 broke arcs inside of axis
- new feature: ensured that arcs inside of axis make use of 'axis cs' and 'axis
direction cs' automatically
- new feature: ensured that (0:1) is evaluated with axis cs
- fixed bug: precision of transformation cartesian to polar was too low (added a
tan2 to fpu)
- fixed bug: z buffer caused 'mesh legend' to produce a compile error
- new feature: added 'y filter/.expression={y==3 ? nan : y}' to simplify coordin
ate filters
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 l
onger;
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 ev
aluations
- simplified 'external lib': added driver auto-detection for pdflatex, lualatex,
xelatex, dvips
(\usepgfplotslibrary{external}, or, with the next PGF release, \usetikzl
ibrary{external})

m the last backwards

ndary
- fixed bug: soft clip decoration failed to apply the transformation matrix
- fixed bug: polar axes and units library resulted in broken bounding box

r coords' absolutely.
use-case: bar plots + nodes near coords which are at, say, y=0 rather than th
eir y value
- new feature: integration of smooth shadings & auto-CMYK conversion
\usepackage[cmyk]{xcolor} or \selectcolormodel{cmyk} will reconfigure pgfplo
ts to use CMYK (document-wide)
- new feature (advanced audience only): programmatic access to data coordinates
during the visualization phase
-> allows much more customization for error bars, stacked plots, nodes n
ear coords.
- wrote beginner tutorials
- fixed bug: error bars and point meta did not work together
