 ## History
 
-### v35.14.1
+### v35.15.0
 
 - 🐞 Fixed parsing of POSIX locale date strings like `"Tue 17 Jun 2025 09:29:01 PM PDT"` (emitted by gnome-screenshot's `CreationTime` tag). Previously these fell through to raw strings, losing the time and timezone.
 - ✨ `extractZone()` now resolves common unambiguous timezone abbreviations (PDT, EST, CEST, JST, NZDT, etc.) to fixed UTC offsets (e.g. PDT → `UTC-7`) as a last-resort fallback when no numeric UTC offset is present. Ambiguous abbreviations (CST, IST, BST, AST) are intentionally omitted.
