New in v.56:
- Zip: the Zip_info type is now controlled (no need to call Delete; additionally, clones are done correctly).
- UnZip.Streams: added Size and Name functions for Zipped_File_Type.
- LZ77: added nice simple LZ77 compressor by Rich Geldreich, Jr.
- (Tools) Added Zip_Dir_List.

New in v.55:
- Zip_Streams: ZS_Size_Type is now 64-bit signed, enabling Zip.Create to capture archive size overflows in Zip_32 mode.
- Zip.Create raises Zip_Capacity_Exceeded when archive creation exceeds the Zip_32 format's capacity: 4GB total size, 65,535 entries.
- Zip.Create is now using an Ada 2005+'s Containers's Hashed Maps; creation is much faster on Zip archives with many entries.
- (Tools) ReZip has a new option for working only with its own internal compression algorithms - those provided by Zip.Compress. This option is useful if external tools are not available.
- New Trained_Compression package: generic streaming encoder-decoder engine with the capability of training the engine with data known in advance, in order to achieve better compression. Not Zip-related.
-!- Minimum required Ada version is now Ada 2005 (was Ada 95 before).
