+# 1.11.2 [2024-10-31]

+

+* Fix performance regression in `zip_stat` introduced in 1.11.

+

+# 1.11.1 [2024-09-19]

+

+* Fix zipconf.h for version number with missing third component.

+

+# 1.11 [2024-09-19]

+

+* Stop searching after finding acceptable central directory, even if it contains inconsistencies.

+* Only write Zip64 EOCD if fields don't fit in normal EOCD. Previously libzip also wrote it when any directory entry required Zip64.

+* Allow bytes from 0x00-0x1F as UTF-8.

+* Add new error code `ZIP_ER_TRUNCATED_ZIP` for files that start with a valid local header signature.

+* `zipcmp`: add `-T` option for comparing timestamps.

+* `zip_file_replace` now removes the target's extra field information.
