 All notable changes to LUOYE Codex Meter are documented here.
 
+## [0.3.5] - 2026-07-13
+
+### Fixed
+
+- Identify five-hour and weekly quota windows by their declared duration instead of their response position
+- Leave the five-hour value and reset time blank when Codex only provides the weekly quota window
+- Preserve compatibility with older app-server responses that omit window duration metadata
+
 ## [0.3.4] - 2026-07-12
 
 Initial public release.
