Hello to all users of pgfplots,

I am proud to announce the release of pgfplots 1.10 . It is available 
for download on 
http://sourceforge.net/projects/pgfplots/files/pgfplots/1.10/ and will 
become available on CTAN within the next 24 hours. MikTeX will mirror 
these files eventually.

Pgfplots 1.10 comes with one major new feature: the ability to fill the 
area enclosed by two plots.

Kind regards

Christian


HISTORY:
1.10:
- new feature: fill between plots (library fillbetween)
- new feature: concatenate intersection segments (library fillbetween)
- fixed bug: xelatex failed to run contour external
- fixed incompatibility with \label and \usepackage{mcaption}
- fixed bug: histograms produced wrong point meta
- fixed bug: histograms reported the wrong 'plot name' and confused 
shifts of bar plots

1.9:
- new feature: asymmetric error bars
- new feature: activated math parser for axis limit arguments, arguments 
in axis cs, and domain argument in log plots
- new feature: stacked bar plots place their 'nodes near coords' 
correctly in the middle and print the increment (compat=1.9)
- new feature: stacked bar plots suppress empty increments (compat=1.9).
- new feature: 'scatter/position=relative|absolute' allow to position 
'nodes near coords' absolutely.
    use-case: bar plots + nodes near coords which are at, say, y=0 
rather than their y value
- new feature: integration of smooth shadings & auto-CMYK conversion
     \usepackage[cmyk]{xcolor} or \selectcolormodel{cmyk} will 
reconfigure pgfplots 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 near coords.
- wrote beginner tutorials
- fixed bug: error bars and point meta did not work together
- fixed bug: stacked plots did not respect 'visualization depends on'
- fixed bug: luatex 0.76 is not backwards compatible; added version switch
- fixed bug: ternary library precision has been improved
- fixed bug: problem with axis limits very close to 0
- fixed bug: colormap specification limit case produced out of bounds 
exception


1.8:
- new feature: tight bounding box even if the axis is no box and bb 
excludes clip path
- new feature: mesh/color input=explicit
- new feature: shader=interp now has drivers for both dvipdfmx and xetex
- new feature: support for more color spaces in colormap definitions
- new feature: shader=interp and device-level gray colorspaces
- new feature: 'contour/contour dir=[xyz]' to draw contours in different 
directions
- new feature: statistics library with boxplot handler (both boxplot 
prepared and automatic computation)
- fixed bug: 3d centered axis lines and label placement (requires 
compat=1.8 or higher)
- fixed bug: axis lines and placement of labels, tick scale labels, and 
reversed axes
     (requires compat=1.8 or higher)
- fixed bug: filtering out coords from a mesh plot failed
- fixed bug: every legend image post was not respected inside of 
\ref{plotlabel}
- fixed bug: high-order patches computed the shader=flat mean in a wrong 
way.
- fixed bug: remember picture inside of pgfplots axes failed (due to 
cell picture)
- fixed bug: now, the tick scale label will be omitted if there are no ticks
- fixed bug: axis box path was not closed
- fixed bug: the bounding box was non-empty even if the axis was hidden.
- fixed bug: auto-alignment of nodes near coords failed for xbar plots
- fixed bug: providing bar width / bar shift in terms of axis units did
     not work with [xy]bar and nodes near coords
- fixed bug: transformation 'data cs=cart' -> polar is more robust now
- fixed bug: code did not compile against pgf 2.00
- fixed bug: patch plot lib and shader=interp,patch type=biquadratic
- fixed bug: context path searching issue (pgfplots.lua)
- fixed bug: shader=interp and dvips driver
- fixed bug: error bars with explicit relative input failed

1.7
- added feature: 'bar shift' and 'bar width' can now be expressed in 
terms of axis units (compat=1.7 or higher)
- fixed incompatibility regression pgfplots 1.6.1 pgf 2.10: layers
- fixed incompatibility pgfplots and imakeidx
- added feature: 'enlargelimits={abs=1cm}', i.e. enlarge by dimension 
rather than unit
- patchplots lib: added patch type=bicubic
- patchplots lib: added support for global paths (fillable)
- patchplots lib: added patch type sampling feature
- patchplots lib: improved usability (documentation and improvements)
- fixed path issues in context: moved lua input file to tex/generic
- fixed bug: \ref{legendimage} inside of legend text was wrong.

1.6.1:
- fixed incompatibility lualatex,shader=interp, and german package 
(introduced in 1.6)

1.6:

layers)
- added support for second colormap in mesh plots (mesh/interior 
colormap name)

- contour plots: added ability to provide list of discrete labels 
(mesh/levels)
- empty lines are interpreted as interruptions in data plots (was 
undocumented since 1.4)
- added more scaling options to 'scale mode=scale uniformly' (affects 
axis equal in 3d
   and \addplot3 graphics)
- fixed wrong implementation of 'axis equal' and 'unit vector ratio' in 3d
   (backwards compatible for 2d, but not for 3d - the 3d implementation 
was plain wrong)
- fixed incompatibility of lualatex and shader=interp
