ZipUtilities Change Log

History

1.13.0 (June 18th, 2021) - Nolan O'Brien

  • Update ZStandard extended support to v1.5.0
  • Update constants of spec based compression methods (including addition of ZStandard as #93)

1.12.0 (June 18th, 2021) - Nolan O'Brien

  • Fix benign decoder bug where the incorrect compression level could be inferred
  • Fix significant bug in string encoding support
    • Need to handle both UTF8 encoded filenames/comments AND DOS Latin US (Code Page 437) encoded (Appendix D of ZIP Specification)
    • Note: Any zip archives created with ZipUtilities v1.11.3 or older that have non-ascii characters for filenames/comments will have mangled filenames/comments as they will decode using DOS Latin US character set instead of UTF8.

  • Update Brotli (v1.0.7) and ZStandard (v1.4.5)
  • Other minor fixes

1.11.2 (September 4, 2018) - Nolan O'Brien

  • Fix vulnerability when zip archive provides malicious output file name

1.11.1 (August 14, 2018) - Nolan O'Brien

  • Update Brotli (v1.0.5) and ZStandard (v1.3.5)
  • Bug fixes for CLI

1.11.0 (April 24, 2018) - Nolan O'Brien

  • Update Brotli (v1.0.4) and ZStandard (v1.3.4)
    • eliminates shared custom dictionary support from brotli

1.10.1 (April 23, 2018) - Nolan O'Brien

  • Add Zip Mode support to noz
  • Fix noz bugs

1.10.0 (June 3, 2017) - Nolan O'Brien

  • add convenience file-to-file compression/decompression functions in NOZUtils.h
  • add CLI for ZipUtilities (called noz)
    • NOTE: Zip Mode is not yet implemented
  • fix NOZUnzipper file size measurement bug

1.9.3 (Feb 20, 2017) - Nolan O'Brien

  • add checksum error code and record validation method to unzipper

    • can map to any encoder with multiple levels now
  • Fix memory leak in Apple extra encoders/decoders
  • Bump up buffer sizes from 4KB to 16KB
  • Update unit tests
  • Update test app
  • rearrange some code paths for better 3rd party codec support
  • improve memory management to reduce memory footprint when multiple encodes/decodes happen

1.8.1 (Nov 18, 2016) - Nolan O'Brien

1.7.2 (Jan 11, 2016) - Nolan O'Brien

  • Provide options when saving a record so that we can support writing an entry to disk without the interim path

1.7.1 (Dec 31, 2015) - Nolan O'Brien

  • Add ability to filter files being added to an NOZCompressRequest when adding files via containing directory path
