inikep/lizard: Lizard (formerly LZ5) is an efficient compressor with very fast decompression.
A fork/variant of LZ4 using interesting tricks. A codec now in Blosc2 when coupled with huffman encoding (and gives better than memcpy compression speeds at 4 threads!)

dropbox/divans: Building better compression together
Apparently the format supports seeks in 4mb chunks but the library doesn't do it natively yet

Building better compression together with DivANS | Dropbox Tech Blog
So another ANS approach like Zstd? But they seem to be splitting apart the problem differently...

ImminentFate/CompactGUI: Visual Interface for the Windows Compact.exe cmdlet
The new compact in windows 10 does special program/file compression using faster realtime codecs, and should be safe for 40GB files (unlike native NTFS compression which uses DEFLATE)

google/brotli: Brotli compression format
optimized for the web and has a static dictionary that has words from a number of common internet character sets/languages, so not quite general purpose...
