Xdelta-3.0s release notes: Faster! Several optimizations to avoid unnecessary arithmeticxdelta3 -1 has faster/poorer compression (xdelta3 -2 is the former configuration)-S djw exposes secondary compression levels as -S djw1 .. -S djw9Removes "source file too large for external decompression" error checkAPI support for transcoding other formats into VCDIFFXdelta-3.0r release notes: Fixes an encoder crash caused by -S djw (secondary compressor) on certain data, new tests for code-length overflowAdds new recode command for re-encoding a delta with different secondary compression settingsFixes API-specific bugs related to non-blocking calls to xd3_encode_input and xd3_decode_inputAdds new examples/encoder_decoder_test.c program for the non-blocking APIAs an example of the new recode command and secondary compression options:$ ./xdelta3 -S none -s xdelta3.h xdelta3.c OUT # 53618 bytes $ ./xdelta3 recode -S djw1 OUT OUT-djw1 # 51023 bytes $ ./xdelta3 recode -S djw3 OUT OUT-djw3 # 47729 bytes $ ./xdelta3 recode -S djw6 OUT OUT-djw6 # 45946 bytes $ ./xdelta3 recode -S djw7 OUT OUT-djw7 # 45676 bytes $ ./xdelta3 recode -S djw8 OUT OUT-djw8 # 45658 bytes $ ./xdelta3 recode -S djw9 OUT OUT-djw9 # 45721 bytes Secondary compression remains off by default. Passing -S djw is equivalent to -S djw6.
