v0.7.0

This is a major release relative to v0.6.x series, thus the compressed bitstreams are not compatible. This release focuses on runtime performance improvements, with the most significant one being a novel implementation based on integer operations. Compared to v0.6.x series, this release is 20% to 50% faster.

A new functionality in this release is *Progressive Access" on 3D SPERR bitstreams. See this page for more discussion.
