Hello users of pgfplots,

I am glad to announce the release of version 1.8!

Note that the version on CTAN is version 1.8, even if it still displays 
version number 1.7 (probably some missing database update on CTAN).

Attaches you find the release notes for version 1.8.

Kind regards

Christian


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:
- added support for layered graphics (main use case: multiple axes and 
layers)
- added support for second colormap in mesh plots (mesh/interior 
colormap name)
- added support for scopes inside of axes
- 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
- fixed bugs/added features around \addplot3 graphics
- fixed bug: colorbar did not support ymode=log
- fixed a couple of minor bugs
- fixed bounding box computation for clip=false,axis lines=none
