Release Notes: This release adds many bugfixes and performance improvements. Accuracy in finding duplicates in Global Dedupe has been improved. SHA256 is now the default block hash algorithm for dedupe, with the ability to change it separately from the chunk verification hash. Overall, many performance improvements have been made, with better parallelism, more SSE vectorization, and faster sorting and improving the segment hash list file handling, resulting in smaller I/O and fewer random accesses. Bugs in calculating in-memory index size has been fixed to avoid overflowing free RAM and swapping to disk.
Release Notes: This release introduces a bunch of fixes and optimizations along with more tests for error conditions. Security has been improved with IPSec-style message authentication and header CRC32 checksums in plain non-crypto mode. Zlib(gzip) compression has been made slightly faster. The rolling hash has been tweaked to improve block size distribution and chunking behavior of deduplication, resulting in an improved dedupe ratio. The compressed archive version has been bumped while retaining compatibility to decompress older non-encrypted versions.
Release Notes: This is a small update release that adds a few fixes and moves to a multiplicative rolling hash as its biggest change. This change improves the hash distribution and generates better dedupe block boundaries for different types of data. This in turn improves dedupe ratio.
