libbrotli1 1.0.7-2build1 (arm64 binary) in ubuntu focal

 Brotli is a generic-purpose lossless compression algorithm
 that compresses data using a combination of a modern variant
 of the LZ77 algorithm, Huffman coding and 2nd order context modeling,
 with a compression ratio comparable to the best currently available
 general-purpose compression methods. It is similar in speed with
 deflate but offers more dense compression.
