Revision history

2020-01-15 PNGOUT, KZIP, ZIPMIX
Updates for all platforms with hardening options enabled during compilation. Addition of ARM 32-bit and 64-bit binaries for Linux. macOS binaries are signed.
2015-09-20 PNGOUT

(Mac OS X only) Rebuilt as 64-bit only with Xcode 7 since building 32-bit with optimisations gives a buggy binary. The previous release was not built with optimisations and was much slower than it should be.

2015-03-19 PNGOUT, KZIP, ZIPMIX

Supports a maximum of 2048 Huffman blocks. Also, 64-bit builds for all tools.
