Dear All
I've made a 1.99 beta test release (called 1.18.99). It would be great
if you could test it, as Veusz has a lot of changed internals (due to
the Py3 compatibility and changing to v2 of the PyQt API). I've also
upgraded Qt in the binary version. This should help with OS X Mavericks
(though I don't have this to test it).

The release doesn't have any huge user-visible changes. I've decided not
to put in the generalisations to 2D datasets (I think more thought is
required here). There are some nice improvements (e.g. renaming
datasets/widgets) and bug fixes, however. Please see the current release
notes below.

Veusz 1.19
----------
http://home.gna.org/veusz/
Veusz is a scientific plotting package. It is designed to produce
publication-ready Postscript/PDF/SVG output. Graphs are built-up by
combining plotting widgets. The user interface aims to be simple,
consistent and powerful.
Veusz provides GUI, Python module, command line, scripting, DBUS and
SAMP interfaces to its plotting facilities. It also allows for
manipulation and editing of datasets. Data can be captured from
external sources such as Internet sockets or other programs.
Changes in 1.19:
* Make code compatible with python3
* Changes to filesystem layout of module
* Separation of python module and resources in source package
(packagers may need to consult INSTALL)
* Move to v2 of PyQt API
* Remove deprecated numpy API from helpers module
* Allow fits dataset names to be blank if prefix/suffix are not
* New ast-based code checker
* Picker uses 1-based index for consistency
* Allow non-text datasets to be used for labels
* Add number->text conversion dataset plugin
* Add binning dataset plugin
* Add notes properties to document, pages and graphs
* Allow more significant figures in float values
* Intelligent choice of significant figures when interactively
changing axis range
* Decrease minimum range of axis
* Add notes setting to document, pages and graphs
Bug fixes:
* Fix crash if other linked axis not initialized
* Fix crash if trying to edit non-editable datasets
* Make ignore exception work in error reporting dialog
* Renaming datasets, widgets and editing data now allow original
text to be edited, rather than being cleared
* Fix line positions on broken axes
Features of package:
Plotting features:
* X-Y plots (with errorbars)
* Line and function plots
* Contour plots
* Images (with colour mappings and colorbars)
* Stepped plots (for histograms)
* Bar graphs
* Vector field plots
* Box plots
* Polar plots
* Ternary plots
* Plotting dates
* Fitting functions to data
* Stacked plots and arrays of plots
* Nested plots
* Plot keys
* Plot labels
* Shapes and arrows on plots
* LaTeX-like formatting for text
* Multiple axes
* Axes with steps in axis scale (broken axes)
* Axis scales using functional forms
* Plotting functions of datasets
Input and output:
* EPS/PDF/PNG/SVG/EMF export
* Dataset creation/manipulation
* Embed Veusz within other programs
* Text, CSV, FITS, NPY/NPZ, QDP, binary and user-plugin importing
* Data can be captured from external sources
Extending:
* Use as a Python module
* User defined functions, constants and can import external Python functions
* Plugin interface to allow user to write or load code to
- import data using new formats
- make new datasets, optionally linked to existing datasets
- arbitrarily manipulate the document
* Scripting interface
* Control with DBUS and SAMP
Other features:
* Data picker
* Interactive tutorial
* Multithreaded rendering
