2.1.2

What's new in 2.1.2

Fixed

• Correct HDR detection — Go2HDR now distinguishes native HDR mode from Windows Advanced Color Management (ACM), so ACM in SDR is no longer treated as active HDR.
• Non-blocking autostart changes — enabling or disabling Start with Windows no longer freezes the application while Task Scheduler is updated.
• Reliable brightness state — the Dashboard no longer displays misleading fallback values when the current screen brightness is temporarily unavailable.
• Improved display recovery — display and brightness monitoring now recover more reliably after sleep, display configuration changes, and restoring Go2HDR from the system tray.
• Safer application lifecycle — improved single-instance handling, tray shutdown, service cleanup, and crash logging.

Improvements

• More precise HDR status — the Dashboard now distinguishes between active HDR, inactive HDR, and a temporarily unavailable display state.
• Safer Windows display integration — hardened DisplayConfig interop and added SDR white-level readback verification.
• Improved SDR Curve tools — added stricter import validation, safer import and export handling, and a more responsive toolbar layout.
• More resilient settings — settings are now saved atomically, invalid files are preserved for recovery, and loaded values are normalized before use.
• Improved update checker — added safer version comparison, trusted release URL validation, clearer network failure reporting, and protection against duplicate concurrent checks.
• Refreshed branding — updated the application, system tray, installer, and project logo.
• Build and maintenance improvements — added automated tests and CI, enabled stricter analyzers and dependency auditing, updated dependencies, and made installer builds safer and repeatable.
