v2 adds pluggable compression, crypto support (also pluggable), an improved API (including much better error messages), easier integration into other tools/libraries, and hugely improved performance. It **is backwards compatible**, but please note that the old `freeze-to-bytes`/`thaw-from-bytes` API has been **deprecated** in favor of `freeze`/`thaw`. **PLEASE REPORT ANY PROBLEMS!** v2 adds pluggable compression, crypto support (also pluggable), an improved API (including much better error messages), easier integration into other tools/libraries, and hugely improved performance.
