1.1.4

Version 1.1.4:

• Increase LZSA2 ratio by 0.04% on average
• New speed-oriented 6502 decompressors by Peter Ferrie
• Improvements to the size-oriented 6502 decompressors by Peter Ferrie
• Another small efficiency improvement for very large matches
• Reduce memory required for compression

1.1.3

Version 1.1.3:

• Fix inefficiency when encoding very large matches for LZSA1 and LZSA2
• Increase LZSA2 ratio by 0.025% on average
• Rewritten LZSA1 8088 jumptable decompressor (LZSA1JMP), now 12.5% faster than LZ4 at -m5

1.1.2

Version 1.1.2:

• Newly compressed LZSA1 files decompress ~0.9% faster on average
• Increase LZSA2 compression ratio by ~0.1% on average
• New option in LZSA1 z80 decompressor to decompress highly compressible datasets 2%+ faster (with the decompressor code being larger)

1.1.1

Version 1.1.1:

• Newly compressed LZSA2 files will decompress 0.7% faster on average
• Update to the LZSA2 Z80 fast depacker, now 0.2% faster
• Update to the LZSA2 Z80 small depacker, a byte smaller and slightly faster
• Implement -stats for decompressor developers
• Fix small efficiency issues in the compressor (resulting in a tiny compression ratio increase for some LZSA2 files)

1.1.0

Version 1.1.0:

• Increase LZSA2 compression slightly further (+0.1% on average)
• Use forward arrivals parser in -m modes for LZSA1 and LZSA2, for a better ratio at the same decompression speed
• Remove old backwards parser
• Update Z80 decompressors

1.0.9

Version 1.0.9:

• Increase LZSA2 compression ratio further
• Speed up LZSA1 compression
• Reduce memory use for compression

1.0.8

Version 1.0.8:

• Small increase in compression ratio for LZSA2
• Small decrease in token count for LZSA2 (newly compressed files will decompress slightly faster)
• Add a missing bound check in C decompressors

1.0.7

Version 1.0.7:

• Create LZSA1 files that decompress faster (with the same ratio)
• Increase compression ratio for LZSA2
• Z80 decompressor speed and size improvements

1.0.6

Version 1.0.6:

• 6502 decompressor fix
• Z80 decompressor fix
• Minor improvements to self-tests

1.0.5

Version 1.0.5:

• Support backward decompression for raw blocks (supported by the Z80 and 6502 decompressors)
• When using -v (verbose) and -r (raw blocks), display the minimum safety distance between the decompressed and compressed data start (or between the compressed and decompressed data end in backward mode)
• 6502 decompressor fix
