* Fix crash when moving line coordinates
* Remove deprecation warnings when compiling with recent Qt versions

Changes in 3.0.1:

the build inside Anaconda. Also Qt and sip parameters can now be given
as environment variables.

* Change default SVG export DPI to 96 to match inkscape and provide
option in dialog to choose export DPI
* Allow %PAGE% and %PAGENAME% in export filename for single page output
* Fix failing fitting due to iminuit differences

EMF exporting
* Update to Qt 5.11.1 and update PyQt and sip in Windows binary
* Build Mac and Linux binaries with EMF export

Changes in 3.0:
* New 3D support for plotting points, functions, surfaces and volumes
* Add --export-option parameter for command line exporting control
* Add templates in preferences for exported file names, add %PAGE00% and
%PAGE000% options for zero-prefixed page numbers, and change %PAGENUM%
to %PAGE%
* In export dialog allow user to specify arbitrary pages to export
* Change miter limit for lines, which fixes some problems when exporting
arrow to PDFs
* Use flat cap on lines with arrows, to avoid line showing through head
* Support datetime64 and string/unicode characters in npy/npz import
* Add \hat LaTeX support

Bug fix release 3 years ago

A bug fix release fixing 2D dataset expressions, 2D XYZ dataset expressions and some built-in functions in function evaluation. There are some better error checks in the CSV and Gnuplot 2D data import routines.

New features and bug fixes 3 years ago

* Now includes n-dimensional data support
* Adds covariance widget
* New markers and arrows
* Colormap sequence for changing colors of widgets

4 years ago

* Text labels can now include Python expressions inside %{{ }}%
* Added built-in functions DATE([fmt]), TIME([fmt]), FILENAME() and BASENAME() when evaluating expressions, which are useful when used in labels
* Added Python dictionary ENVIRON when evaluating expressions, to obtain values from environment variables
* Added DATA(name, [part]) function to expression environment for accessing values from datasets, useful for function evaluation or labels
* Added SETTING(path) function for expression evaluation to obtain values of settings
* Added ESCAPE(text) function to environment, which allows LaTeX special characters to be displayed in labels
* Add fractions and percentages units to polar plot
* Allow number of spokes to be varied in polar plot
* Widgets can be clicked holding down shift or ctrl, to add or toggle their selection
* Add K. Moreland's cool-warm colormap (thanks to S. Richardson)
* Added further green-map, blue-darkred, blue-darkorange, brown-blue and blue-orange colormaps from Oregon geography dept.
* Add logarithm and exponential dataset plugins
* Add Wipe() command to embedding interface to clear document
* Add File->Reload menu option to reload from saved document
* Add tooltip to items in FieldWidget showing widget path

Bux fixes:
* Fix transparency with bar plot
* Use getcwdu() for python2 to avoid bugs combining paths
* Handle inf/nan when converting to human readable form in plots
* Fix CreateHistogram on command line without binparams parameter
* Handle empty 2D dataset import with grid at edge enabled
* Do not allow error bars on imported CSV non-numeric data
* Handle missing argument in \size
* For data edit dialog, allow 1D dataset to replace 2D dataset
* Crash if zoom to be height when height is zero
* Fix problem with 2D import if error message is in unicode
* With axis-function widget catch result if greater than 1 dimension
* Fix cloning for datasets with / in name
* Fix crash in embedding if plot window closed while rendering in progress
