v2.2.0

🚀 Features

• Expose ZipArchive::central_directory_start (#232)

v2.1.6

🐛 Bug Fixes

• (#33) Rare combination of settings could lead to writing a corrupt archive with overlength extra data, and data_start locations when reading the archive back were also wrong (#221)

🚜 Refactor

• Eliminate some magic numbers and unnecessary path prefixes (#225)

v2.1.5

🚜 Refactor

• change invalid_state() return type to io::Result

v2.1.4

🐛 Bug Fixes

• fix(#215): Upgrade to deflate64 0.1.9
• Panic when reading a file truncated in the middle of an XZ block header
• Some archives with over u16::MAX files were handled incorrectly or slowly (#189)
• Check number of files when deciding whether a CDE is the real one
• Could still select a fake CDE over a real one in some cases
• May have to consider multiple CDEs before filtering for validity
• We now keep searching for a real CDE header after read an invalid one from the file comment
• Always search for data start when opening an archive for append, and reject the header if data appears to start after central directory
• deep_copy_file no longer allows overwriting an existing file, to match the behavior of shallow_copy_file
• File start position was wrong when extra data was present
• Abort file if central extra data is too large
• Overflow panic when central directory extra data is too large
• ZIP64 header was being written twice when copying a file
• ZIP64 header was being written to central header twice
• Start position was incorrect when file had no extra data
• Allow all reserved headers we can create
• Fix a bug where alignment padding interacts with other extra-data fields
• Fix bugs involving alignment padding and Unicode extra fields
• Incorrect header when adding AES-encrypted files
• Parse the extra field and reject it if invalid
• Incorrect behavior following a rare combination of merge_archive, abort_file and deep_copy_file. As well, we now return an error when a file is being copied to itself.
• path_to_string now properly handles the case of an empty path
• Implement Debug for ZipWriter even when it's not implemented for the inner writer's type
• Fix an issue where the central directory could be incorrectly detected
• finish_into_readable() would corrupt the archive if the central directory had moved

🚜 Refactor

• Verify with debug assertions that no FixedSizeBlock expects a multi-byte alignment (#198)
• Use new do_or_abort_file method

⚡ Performance

• Speed up CRC when encrypting small files
• Limit the number of extra fields
• Refactor extra-data validation
• Store extra data in plain vectors until after validation
• Only build one IndexMap after choosing among the possible valid headers
• Simplify validation of empty extra-data fields
• Validate automatic extra-data fields only once, even if several are present
• Remove redundant validate_extra_data() call
• Skip searching for the ZIP32 header if a valid ZIP64 header is present (#189)

⚙️ Miscellaneous Tasks

• Fix a build error
• Fix boxed_local warning (can borrow instead)
• Partial debug
• Fix more errors when parsing multiple extra fields
• Fix an error when decoding AES header
• Fix an error caused by not allowing 0xa11e field
• Bug fix: crypto_header was being counted toward extra_data_end
• Bug fix: revert a change where crypto_header was incorrectly treated as an extra field
• Fix a bug where a modulo of 0 was used
• Fix a bug when ZipCrypto, alignment and a custom header are used
• Fix a bug when both ZipCrypto and alignment are used
• Fix another bug: header_end vs extra_data_end
• Fix use of a stale value in a debug_assert_eq!
• Fix: may still get an incorrect size if opening an invalid file for append
• Fix: may need the absolute start as tiebreaker to ensure deterministic behavior

v2.1.3

🐛 Bug Fixes

• Some date/time filters were previously unreliable (i.e. later-pass filters had no earliest-pass or latest-fail, and vice-versa)
• Decode Zip-Info UTF8 name and comment fields (#159)

🚜 Refactor

• Return extended timestamp fields copied rather than borrowed (#183)

⚙️ Miscellaneous Tasks
