A C\C++ library and command-line tools for Diff & Patch between binary files or directories(folder); cross-platform; runs fast; create small delta/differential; support large files and limit memory requires when diff & patch.
create a delta: $hdiffz -m-4 -SD -c-zstd-21-25 -d oldPath newPath outDiffFile ; if file is very large, try changing -m-4 to -s-64; apply the delta: $hpatchz oldPath diffFile outNewPath
I did not tested linux_riscv32 cmdline on riscv linux PC
