More weightings and residuals for regression and
nonlinear fit were added. Wavelet and hankel
transformation were added, and analysis functions
were improved. Additionally improved was not only
the surface and qwt 3D plot but also the behavior
with nonlinear scales and the support for LaTeX
labels. LabPlot now can import/export data from/to
PostgreSQL, MySQL, and other sources via the
KexiDB and Origin opj projects (Origin worksheets
only). The scripting support was completely
rewritten and many bugfixes were made.
