Nonlinear fit with any user-defined function with
up to 9 parameter was added. One can now configure
all default values for plot style and symbols. It
is now possible to clone graphs and delete/clone
plots easily. The import/export settings were
improved with support for binary data.
Additionally, LabPlot now supports a speed mode
for large data sets and a data mode for inspecting
data points. Marker, improved axis grids, and
masking of data points (in spreadsheets and plots)
were added in this release.
