v0.0.9

Stable release v0.0.9

This is a major update which is MANDATORY FOR EVERYONE.

Grid2d_v2 optimized algorithm is supported in addition to Grid2d (old version). The Node now supports both algorithms for block verification.

Grid2d_v2 was tuned up to reduce hash duplicate occasions and turn "hidden" difficulty into the actual real number without distortion taking place while using Grid2d (old version). 3D object recognition precision was increased, and the recognition error - reduced, which being put together increases the variety of acceptable object shapes.
