0.4.3 11 Nov 2026

Added

• Pace tick on the usage bars. The Claude and Codex 5-hour and weekly bars show a thin mark at how much of the window has passed, so you can see at a glance whether usage is ahead of or behind the clock. It only appears on fresh readings with a known reset time (#14, #99, thanks @FramY2).

Fixed

• **A broken config.json is no longer lost.** If the settings file cannot be read (a crash mid-write, a typo in a hand edit), CCT keeps its exact contents in config.json.bad before loading the defaults, so you can recover your settings (#88, #109, thanks @DiulioAires).

Changed

• Lighter Codex offline fallback. When CCT falls back to the Codex session logs, it now opens only the 20 newest logs changed in the last 7 days and reads just the last 256 KB of each, instead of loading whole files and walking the entire history. Less memory and disk work on every refresh while offline, and much less conversation content passes through memory (#3).
• **Fewer codex processes during long outages.** After the codex app-server fallback fails, CCT skips it for 5 minutes, doubling up to 30, and goes straight to the session logs. Any live reading resets the wait (#63).
• A slow provider no longer holds up the other. Claude and Codex are now fetched on their own background threads. While Codex waits for its offline fallback to time out, *Refresh now*, an account switch or the refresh after a reset still updates Claude right away (and the other way round). Each provider is fetched exactly as often as before, and a disabled provider is still never fetched (#89, #110, thanks @FramY2).

0.4.2 10 Nov 2026

Changed

• About 40% less CPU while idle. The strip no longer repaints a frame that is already on screen, keeps its bitmap and Direct2D target between frames, and re-reads the Start button's position instead of searching the taskbar for it every time. Nothing looks or updates differently. Measured over 10 minutes at the default settings: 3.58 s of CPU time before, 2.09 s after (#86, #90, #91, #94, #95).

0.4.1 10 Nov 2026

Added

• Show remaining instead of used (opt-in). A Settings switch that shows what is left of each limit (38% instead of 62%, 38% left in the tooltip). Bar colors still follow usage, and errors still show — (#31, #80, thanks @DiulioAires).

Changed

• About 38% smaller. The release .exe drops from ~973 KB to ~607 KB: usage requests now go through Windows' own WinHTTP instead of the bundled ureq HTTP and TLS stack. TLS is still the system's (Schannel and the Windows certificate store), and every rule the old client had is kept and tested: HTTPS only, no redirects, certificate checks always on, the same status handling, no headers in error text, and the same ALL_PROXY / HTTPS_PROXY / HTTP_PROXY / NO_PROXY proxy settings, including user:password@ for proxies that ask for it.
  • TLS 1.2 or newer only.
  • A proxy variable with a scheme WinHTTP can't use (socks5://, https://) now fails the request instead of quietly going direct.
  • A server that accepts the connection and never answers ends the request in at most ~12 s (WinHTTP rounds its timeouts to ~4 s steps) instead of exactly 10 s (#83, #84).
• Right-click menu. Items are grouped (Refresh now and Copy usage; Claude account; Settings… and Start with Windows; Exit), Refresh now is the bold default like the double-click, and every item has a one-letter shortcut shown on its right. The letters are the same in every language (#58, #82).

Fixed

• The strip no longer covers its own right-click menu a few seconds after it opens over the strip (#82).
• Keep-alive no longer kills what the CLI leaves running on success. The process tree is still killed when the CLI times out (#75, #81, thanks @FramY2).

0.4.0 9 Nov 2026

Added

• Claude account switcher. Save your paid Claude Code logins (Pro, Max, Team, Enterprise) and switch between them from the right-click menu (Claude account), without /logout and /login (#53, #54, #55, #56, #57).
  • Claude Code picks up the new login on its next request; no restart is needed.
  • Always manual: the app never switches on its own and never rotates accounts.
  • Asks first when a Claude Code task is running or waiting for your answer (for example on a permission prompt), because the rest of that task would run on the other account.
  • Each entry shows the plan and the usage last seen on that account, and warns when a saved login is about to expire (⚠ login expires in Nd) or has expired (⚠ needs /login).
  • Saved logins are encrypted with Windows DPAPI for your user. A switch holds Claude Code's own lock files, backs up the account being left, writes through a temp file, and restores everything if any step fails.
  • Applies to the claude CLI only: the Claude desktop app keeps its own login. Not supported when CLAUDE_CONFIG_DIR is set.
• Account labels on the strip. A short label (up to 5 characters, default P) before the Claude and the Codex gauges, as a badge in each service's color, tells you which account the numbers belong to, e.g. P for personal and W for work. Each saved Claude account has its own label, so a switch changes it too. Edit it in Settings; leave it empty to hide it (#74).
• Quota alerts (opt-in). A Windows notification when fresh Claude or Codex usage crosses 80% or 95% of a window (thresholds in config.json), showing the highest threshold crossed per window. Off by default: turn it on in Settings (Notify near limit). It never replays old crossings, waits for a real reset before warning again, and stays quiet in full screen, presentations and quiet hours (#15, #73, #76, thanks @gnevesx).

Fixed

• Codex and *Keep login active*: when the codex app-server fallback or a login status command times out, the whole process tree is now killed, so a .cmd shim can no longer leave node or the CLI running in the background (#62, #75, thanks @FramY2).
• Windows 10: Settings and the tooltip now explain why the strip stays hidden (there is no free taskbar corner there) instead of showing nothing (#64, #71, thanks @Daiyuanranfeng; confirmed by @pedrohassen).

Changed

• Settings window redesigned in the style of the Windows 10/11 Settings app: cards, on/off switches, item chips and clear login status lines. It follows the Windows light or dark app theme and your accent color, live, uses system colors in High Contrast, adapts to each monitor's scaling, and scrolls when the screen is short. Changes apply immediately (no OK/Cancel; Esc closes). Switches and chips are real checkboxes underneath, so the keyboard and Narrator keep working. Design rules are in the new DESIGN.md (#58).
• Changing visible items or the hardware interval no longer triggers a limits fetch.
• Codex's color is now blue (#3b82f6) instead of green, on the strip and in Settings.
• Privacy: the account switcher is the one exception to read-only credentials. Only when you pick an account to switch to does the app write ~/.claude/.credentials.json and the oauthAccount key of ~/.claude.json; *Save current account* only reads them. The Codex login is never written, and tokens are never refreshed in-app. README, SECURITY.md and AGENTS.md are updated.

0.3.0 9 Nov 2026

Added

• Codex: when the usage endpoint fails, live limits are read from the installed Codex CLI (codex app-server, hidden, 5 s timeout) before falling back to the session logs (#25, #60, thanks @FramY2).
• Tooltip shows the time left until each limit resets (#30, thanks @gnevesx).
• Tooltip says why the last update failed when the data shown is stale (#49).
• Limits refresh right after a known reset time passes (#32).
• *Copy usage* in the right-click menu (#33).
• Double-click the strip to refresh now (#34).

Fixed

• Windows 10: the strip no longer covers the Start button and the search box (#43, reported by @pedrohassen).
• Windows 10: no more setup hints for taskbar settings that only exist on Windows 11 (centered icons, Widgets button) (#44, #61, thanks @fiower-grass; reported by @pedrohassen).
• GPU shows — instead of 0% when its counter has no valid data (#1, #9, thanks @ricklaroque).
• Hidden disks stay hidden when Windows re-enumerates the disks (#4, #41, thanks @DiulioAires).
• The strip hides when painting fails instead of keeping a stale frame (#2, #42, thanks @pedrohassen).
• *Keep login active* (experimental): claude auth status now runs under a hidden pseudo console, so Claude Code treats it as interactive and can renew an expired login, as it does in a console window (#52, #59, thanks @jasestu for the report and the analysis). Both CLIs are now killed after 60 s. Renewal of an already-expired token is still being verified; help wanted in #65.

Changed

• Privacy: besides *Keep login active*, CCT now also runs a program when the Codex usage endpoint fails: the local codex app-server, hidden, with its output used only for the limits. The README's Privacy section is updated.

Documentation

• Code signing policy for the SignPath Foundation application (CODE_SIGNING.md), and notes on the pending winget package.

0.2.1 4 Nov 2026

Added

• Claude tooltip shows per-model weekly limits (Opus, Sonnet) and extra usage when the account has them (#24, thanks @gnevesx).

Fixed

• Codex: the weekly limit no longer shows as the 5-hour one; windows are classified by their reported duration (#22, thanks @gnevesx).
• HTTP requests refuse plain HTTP and never follow redirects, so headers cannot leak (#7).
• *Keep login active* runs the CLI by absolute path from System32 instead of cmd /C (#6).

Changed

• Executable is ~135 KB smaller (about 800 KB): the Universal CRT comes from Windows and the build is optimized for size.

Security

• Releases carry signed build provenance attestations; see *Verifying a release* in SECURITY.md (#19).
• CI and release builds use Actions pinned by commit SHA and --locked dependencies (#8), and fail if the executable exceeds 1 MB (#18).

0.2.0 30 Oct 2026

Changed

• Renamed to CCT (claude-codex-taskbar): the executable is now claude-codex-taskbar.exe.
• Windows 10 is supported (validated), in addition to Windows 11.

Added

• Automatic upgrade from v0.1.x: closes the old widget-usage-windows.exe, copies its settings and moves *Start with Windows* to the new executable.
• Experimental, opt-in *Keep login active* for Codex (codex login status), alongside Claude Code.

0.1.0 30 Oct 2026

Added

• First release: taskbar strip with CPU, RAM, GPU and per-disk activity, Claude Code and Codex 5-hour/weekly limits, tooltip with reset times, settings window, start with Windows, English and Brazilian Portuguese UI.
