v1.0.0 — Stable release

First stable release of Monitor Brightness Control — cross-platform brightness, contrast, color-temperature and input-source control for every monitor connected to your machine.

What's new since 0.1.0

• Time-of-day schedules — apply a brightness preset on specific weekdays and times, target individual monitors or all of them.
• Profiles get sliders, not JSON — per-monitor toggles for brightness, contrast and color preset; current monitor values are pre-loaded when you create a new profile.
• App identifier is optional — empty profiles can still be applied manually from the new Apply profile submenu in the system tray.
• Instant startup — monitor enumeration now runs in a background thread, so the tray and main window appear immediately even on machines where WMI brightness queries are slow.
• Live brightness cache — the tray menu and main window no longer pay DDC/CI roundtrips on every render.
• About tab shows the live version and a prominent disclaimer.
• Tray Quit actually quits — closing the window keeps the tray alive, but the tray's Quit item exits cleanly.
• Six UI languages — English, Deutsch, Español, Français, Italiano, 日本語. OS locale is auto-detected.
• Rust edition 2024 (Rust 1.85+).
• License: switched from MIT/Apache-2.0 to source-available proprietary; see LICENSE.

Intel-Mac users: the Apple Silicon `.dmg` runs under Rosetta 2 on macOS 11+. A dedicated x86_64 build is not produced because GitHub-hosted macos-13 runners are scarce.

Platform support

• ✅ Windows 10 / 11 — primary development target.
• ⚠ macOS / Linux — compile cleanly, need hardware-on-hand validation.

For Linux DDC/CI without root, install `packaging/linux/90-monitor-brightness.rules` from the source tree.

v0.1.0 — Initial release

First public-ish build of Monitor Brightness Control — cross-platform brightness, contrast, color-temperature and input-source control for every connected monitor.

Highlights

• Per-monitor sliders in the main window and the system-tray menu.
• Configurable global hotkeys — brightness ± , night-mode toggle, blackout, show / hide window.
• Per-app profiles bound to executable name (Windows), bundle id (macOS) or WM_CLASS (Linux). Per-monitor overrides for brightness, contrast and color preset. App binding is optional — empty-app-id profiles apply manually from the tray submenu.
• Time-of-day schedules with per-weekday and per-monitor scoping (e.g. brightness 80 % on weekdays at 08:00, dim everything to 30 % after 22:00).
• Sun-position auto-dim around local sunrise / sunset, fully offline.
• Multi-monitor sync with configurable offset.
• Six UI languages out of the box: English, Deutsch, Español, Français, Italiano, 日本語. OS locale is auto-detected.
• Tray Apply-profile submenu appears as soon as you have one or more profiles.
• Native Rust core (brightness-core) — no Electron, ~7 MB shipped binary.
• Instant startup — monitor enumeration runs in a background thread post-setup, so the tray and main window appear immediately.
