Synopsis

Description

 # Version 1.12.1 - 2026-10-14

 * Protect against denial of service attack (advisory [GHSA-m3wq-j48p-jxwh](https://github.com/nih- at/libzip/security/advisories/GHSA-m3wq-j48p-jxwh), actually fixed in 1.12).

 ## Version 1.12 - 2026-10-07

 * Keep order of local extra fields, even if an identical extra field is present in the central directory.
 * Add `zip_source_at_eof()` and `ZIP_SOURCE_AT_EOF`.
 * Consistently report CRC and decryption errors when reading exactly to end-of-file.
 * Remove Mbed TLS support - the required functions were made private.
 * Make non-random tests work on macOS and Windows by using a special version of libzip.
 * Securely clear passwords and key material before freeing it.
 * Use SipHash hash function with per-table random keys. This prevents hash flooding attacks.
 * Add compile time option to limit LZMA window size.
 * Add more comprehensive fuzzers for metadata and write code paths.
 * Fix `zip_source_is_seekable()`.
 * Fix setting incorrect WinZIP AES version in some cases.
 * Further improvements to overall stability and other minor adjustments have been made.
