lrzip ChangeLog
NOVEMBER 2019, updates to version 0.631, Peter Hyman
* Fixups to Assembler code in configure.ac lzma/C/Makefile.am by using
optimized code from p7zip LZMA SDK 16.02. Now works for 64 and 32 bit using
one optimized source. Hack to allow libtool to compile and link assembler
code.
JUNE 2016, version 0.630 Con Kolivas, Peter Hyman, Petr Písař, Joel Fredrikson
* checksum.buf should only be changed after the semaphore wait

@ -21,5 +21,3 @@ Consider ncurses version or even GUI one.
Consider using LZMA Filters for processor-optimised
coding to increase compression.
Get the ASM working on 64bit - it's only the CRC check so probably no point.
