deft4j v1.0.0-beta-17

• Added basic deflate block merging. deft4j will now merge deflate blocks if the combined size would be smaller than the individual blocks. This may majorly increase time spent optimising files, so an option is provided to disable block merging if needed. This option may also be useful for other scenarios involving mixing compression using existing block splits. Block merging is enabled by default.
• Minor performance improvements.

To use this as a command line utility, download the file named "deft4j-cmd-all.jar".

deft4j v1.0.0-beta-16

Fixed a bug causing invalid output when an invalid value was provided for the number of Zopfli iterations.

To use this as a command line utility, download the file named "deft4j-cmd-all.jar".

deft4j v1.0.0-beta-15

• Small improvements to dynamic header encoding
• Files which contain multiple deflate streams are processed in a more stable order

To use this as a command line utility, download the file named "deft4j-cmd-all.jar".

deft4j v1.0.0-beta-14

• Fixed converting APNG files to GZip. fdAT chunks are now converted properly.
• Added a command to GZip compress a file using the built-in compressors with deft4j optimisations.
