v0.8.2
Small decompression speed improvement
API : ZDICT_getDictID(), ZSTD_sizeof_{CCtx, DCtx, CStream, DStream}()
+CLI Legacy support for formats v0.4+
Enhanced documentation, by Przemyslaw Skibinski
Fixed : compression fails on specific huge files, bug introduced in v0.8.1, reported by Jesse McGrew
