Fyn Engine changelog

Every version, newest first.

v0.8.1: patch (UI theme, FPS, bloom fix)

Fixed: bloom could wash the whole scene out to white with black speckles (seen on Windows GPUs).
Some shader maths could produce invalid pixels (NaN): pow() of a value a hair below zero, or a zero-length normal. These pixels showed as black specks, and the bloom blurred them into a white flash.
The shaders now clamp those values (lit, grass, water).
The bloom pass now throws away any invalid pixel before blurring.
New: Show FPS
Use the FPS toggle in the viewport toolbar or View → Show FPS.
The readout (FPS and frame time) sits at the bottom-left of the viewport. Its colour shows speed: teal = smooth, amber = OK, red = slow.
The same setting shows FPS in exported games (Settings → Show FPS).
New UI theme, "Deep sea"
Abyss-navy panels, teal surfaces and sea-foam accents.
Coral is used only for the Play button.
Teal tab underlines and a sea-foam drag-and-drop highlight.
The web player's loading screen matches.
Version number fixed. It was stuck at 0.5 (CMake) and 0.4 (About box). Both now come from one place, and the editor title bar shows it.
Added this changelog.
