[1.1.1]

[1.1.0]

Added

  • Support for decoding LZMA.

Changed

  • FileOptions now has the subtype SimpleFileOptions which implements Copy but has no extra data.

[1.0.1]

Changed

  • The published package on crates.io no longer includes the tests or examples.

[1.0.0]

  • MSRV increased to 1.67.

Fixed

  • Fixed some rare bugs that could cause panics when trying to read an invalid ZIP file or using an incorrect password.

Fixed

  • Fixed an issue where code might spuriously fail during write fuzzing.

Added

[0.8.0]

Deleted

  • Methods start_file_aligned, start_file_with_extra_data, end_local_start_central_extra_data and end_extra_data (see below).

Changed

  • Alignment and extra-data fields are now attributes of [zip::unstable::write::FileOptions], allowing them to be specified for add_directory and add_symlink.
  • Extra-data fields are now formatted by the FileOptions method add_extra_data.

[0.7.0]

Fixed

  • Calling start_file with invalid parameters no longer closes the ZipWriter.
  • Attempting to write a 4GiB file without calling FileOptions::large_file(true) now removes the file from the archive but does not close the ZipWriter.
