# 1.11 [2024-09-19]

# 1.10.1 [2023-08-23]
* Add `ZIP_LENGTH_TO_END` and `ZIP_LENGTH_UNCHECKED`. Unless `ZIP_LENGTH_UNCHECKED` is used as `length`, it is an error for a file to shrink between the time when the source is created and when its data is read.

* Allow reading changed file data.
* Fix handling of files of size 4294967295.
* `zipmerge`: copy extra fields.
* `zipmerge`: add option to keep files uncompressed.
* Switch test framework to use nihtest instead of Perl.
* Fix reading/writing compressed data with buffers > 4GiB.
* Restore support for torrentzip.
* Add warnings when using deprecated functions.
* Allow keeping files for empty archives.
* Support mbedTLS>=3.3.0.
* Support OpenSSL 3.
* Use ISO C secure library functions, if available.
# 1.9.2 [2022-06-28]
* Fix version number in header file.

* Add `zip_source_window_create()`.
* Add `zip_source_zip_create()` variant to `zip_source_zip()`.
* Allow method specific `comp_flags` in `zip_set_file_compression()`.
* Allow `zip_source_tell()` on sources that don't support seeking and `zip_ftell()` on compressed data.
* Provide more details for consistency check errors.
* Improve output of `zipcmp`.
* In `zipcmp`, don’t ignore empty directories when comparing directory listing.
* Treat empty string as no password given in `zip_file_set_encryption()`, `zip_fopen_encrypted()`, and `zip_set_default_password()`.
# 1.7.3 [2020-07-15]
* Support cmake < 3.17 again.
* Fix pkgconfig file (regression in 1.7.2).
