AI Usage Viewer

Changelog

v1.1.1 — 2026-07-15

Updated the "View all changes" link in the update notification to the new distribution site URL, following the product site migration

Adapt to Codex's spec change where only the weekly limit remains. Usage is now shown and notified correctly even when only the weekly window is returned (previously the weekly window was mislabeled as the 5-hour window and notifications could be missed)
Usage windows absent from the response (such as the retired 5-hour window) are now automatically hidden from the panel, tray, and notifications
Added a config-file option (codex_five_hour_enabled, defaults to auto-detect) to toggle the 5-hour window display in case the 5-hour limit returns

Fixed reset times showing one minute earlier than the actual reset boundary
Fixed usage showing a "fetch error" right after the reset time (a transiently incomplete window no longer fails the whole fetch; the other window keeps displaying and the value self-heals on the next poll; applies to both Claude and Codex)
