These release notes cover the stable 1.18.4 releases, from the original stable release through this update.

1.18.4

Notice: Vibeshine may trigger false-positive antivirus alerts. Details and workarounds are documented here: #59

Restored exact virtual-display activation on ordinary Windows display topologies, preserving driver-created displays and encoder capabilities when direct activation is unavailable.
Kept the virtual-display topology active while HDR preparation retries, then fell back to SDR without bouncing the physical desktop.
Applied explicit HDR display profiles to the physical display when a requested virtual display falls back after setup failure.
Kept extended virtual displays out of clone groups so Windows accepts exact-target activation.

Fixed CI/CD incorrectly retaining the beta version for a stable release, which could cause false update notifications.

Fixed unnecessary work on the v2 display-helper fast path and switching between helper engines.
Fixed virtual-display activation waiting on unstable monitor identity, recovery-state cleanup making the host unreachable, and stale portrait pointer rotation after restore.
Fixed Steam audio device ownership and restoration across app resumes and interrupted endpoint visibility changes.
Fixed Lossless Scaling launcher selection so a game path cannot be launched as the scaling tool.
Defaulted AMD encoding to the supported FFmpeg AMF path while keeping native AMF as an explicit experimental option.

Fixed incomplete physical-monitor restoration after virtual-display sessions, keeping missing monitors pending and preserving the last verified layout when recovery fails.
Fixed headless startup failing to discover usable encoder capabilities before an interactive desktop is available.
Fixed virtual capture selecting the wrong monitor when multiple virtual displays change enumeration order.
Restored global virtual-display inheritance for legacy app profiles while preserving explicit per-app display choices.
Fixed scaling-only Lossless Scaling profiles being ignored for generic Playnite launches.
Fixed large troubleshooting log exports blocking the Web UI or timing out.
Restored the legacy Web UI's ability to retrieve current GitHub release details.
Added an explicit opt-in for configured RTSS limiter modes on virtual displays while retaining the default Reflex behavior.
Fixed command-editor labels, removal-button accessibility, and empty-state clarity in the v2 Web UI.
Reduced Windows trust prompts during signed virtual-display driver upgrades and removed obsolete self-signed trust when it is no longer needed.
Removed the unused ViGEmBus force-uninstaller to avoid leaving a manually installed driver partially removed if the script is run.
Fixed out-of-tree builds producing an incorrect 0.0.0 version and TrueHDR runtime staging deleting existing build outputs.

These fixes were backported from 1.19.0-beta.1 and 1.19.0-beta.2, published August 20 and August 21, respectively, after at least one week in beta.
