What's new
HDR:
presets now look right with Windows HDR on (NVIDIA), Manual and the display menu show when a display is in HDR.
Your preset stays on:
if Windows or a game resets your screen's colors (sleep, display changes, some fullscreen games), it comes back by itself.
OBS:
Sync to stream now matches your screen exactly, including Vibrance, Black Point, per-color settings and your curve.
Edit saved presets:
Saved → Edit in Manual, then Save preset → Update preset, or save it as a new one.
Profiles:
a new switch loads the ★ preset without turning it on when its game starts or you switch to the profile.
Achievements
8 new, 16 in total:
Routine Visit, Showman, Contributor, Quick Draw, Master Mason, Crowd Pleaser, Community Legend and All-Seeing.
Past progress counts: presets you've shared, their saves, and presets with a custom curve.
New hand-painted art
for all of them. Hover an unlocked one in Settings → Achievements to see it large.
Renamed: Curator, Night Herd, Every Piece in Play, Strike at Dawn and A Long Road.
Fixes and performance
Steam connects even if GammaBoost+ starts first
(Start with Windows), and achievements earned while it wasn't connected now unlock.
Lighter in the background:
various performance improvements.
Get help (Settings → About) opens our Discord.
Fixed Enter reopening the save dialog, and a rare startup issue that left the window hidden.

GammaBoost+ 1.4.1 — Default Profile Fix
Fixes · Your Default profile turns on at launch: GammaBoost+ now opens in your profile with its ★ preset on screen, as the profile's "★ turns on when you switch to this profile" setting says. Before, it opened on the last preset you used, even one from another profile, switched off. · Back to your Default profile after a game: when a game with its own profile closes, your Default profile's ★ pr…
