Release v0.34.0 is out of the oven.

This release contains no major API breakage, but all around improvements and bug fixes.

hplot

hplot/vgop: a new package to implement JSON serialization of gonum/plot canvases

p := hplot.New()
// ...
err := hplot.Save(p, 10*vg.Centimeter, 20*vg.Centimeter, "plot.json")

hplot is now using gonum/plot@v0.14.0 which has the necessary infrastructure to get nicer timeseries axes. See the provided examples (here) for the hplot.Ticks type.
hplot has gained some basic capability to display the legend (a color palette with numbers) of a 2D plot. See the provided example.
added a convenience forward function for gonum/plot/plotter.NewLinePoints (as hplot.NewLinePoints)

added support for ROOT 6.28/04
groot/rjson: a new package to implement JSROOT-compatible JSON serialization of groot's histogram types (rhist.H{1,2}x)

h, err := f.Get("h1d")
raw, err := rjson.Marshal(h)

See the complete example here.

groot/rtree is now able to read trees created by Geant4 in multithreaded mode (see here for more details).
added support for the "new" TLeafG branch.
