LZ5 and Lizard
From Just Solve the File Format Problem
LZ5/Lizard is a compressed data format, and compressed file format.
The original name was LZ5. There were two major versions of LZ5: 1.x and 2.x. In 2017, LZ5 2.x was renamed to Lizard 1.x. (Or something like that. More research may be needed here.)
LZ5/Lizard was apparently developed by Przemyslaw Skibinski, based on LZ4 source code by Yann Collet.
