#zstd 1.5.7 is out and it's honestly quite amazing.
Highlights for me are:
- ~10% faster at small block sizes common in databases(=filesystems?)
- Limited multi-threading by default. (You could already enable it manually; this only concerns the defaults.)
- A new --max flag that inches zstd closer to #lzma/#xz. We'll need to see more testing on how close exactly but it's impressive they managed to broaden the range this far in a single format.
BZip3
在 Hacker News 上看到 BZip3 的連結：「Bzip3: A spiritual successor to BZip2 (github.com/kspalaiologos)」。
雖然名字看起來與 bzip2 有關，但看起來是不同的人弄出來的東西，不過有些經典的演算法有留下來用，像是 Burrows-Wheeler transform。
另外值得一提的是，bzip2 是 1996 年出的 (不過 1.0 大約是 2000 年時出的)，BZip3 的第一個 release 在 2022 年，這段時間也累積了不少有趣的演算法可以用。
無損壓縮中如果期望有比較的壓縮率，目前比較常用的應該是 LZMA 類的演算法 (差不多是 2001 年出現的)，用的工具通常會是 X
