1.3.0

Version 1.3.0:

• Max out ratio when not using --favor-decSpeed
• Fix minor issue that slightly affected the ratio on some files
• Compress faster

1.2.2

Version 1.2.2:

• Increase compression ratio for some types of files

1.2.1

Version 1.2.1:

• Cover all modes in automated testing

1.2.0

Version 1.2.0:

• Add automated testing
• Tidy up the codebase

1.1.4

Version 1.1.4:

• Support legacy frame format
• Add in-memory decompression benchmark

1.1.3

Version 1.1.3:

• Add --favor-decSpeed option (beats lz4 --favor-decSpeed in both size and decompression speed)

1.1.2

Version 1.1.2:

• Bugfix release

1.1.1

Version 1.1.1:

• Implement support for dictionaries
• Fix max block size reduction for source files smaller than the specified block size

1.1.0

Version 1.1.0:

• Reduce token count by 7% by trading 0.01% compression.

lz4ultra beats lz4 -12 --favor-decSpeed in both size and token count. It now produces 7% less tokens than all the other lz4 encoders while keeping the compressed size within 0.01% of the "favor ratio" methods.

1.0.4

Version 1.0.4:

• Reduce token count by 1% without changing the compression ratio
• Add strict limits when decompressing in-tool
• Improve in-tool decompression speed
