### Changed

- Increased the default low-processor-usage mode FPS limit (60 → 125).

- Redesigned the Godot logo to be more legible at small sizes.

### Deprecated

- `opacity` and `self_opacity` are replaced by `modulate` and `self_modulate` in all 2D nodes, allowing for full color changes in addition to opacity changes.

### Removed

- Skybox support.
  - Replaced with panorama skies, which are easier to import.
- Opus audio codec support.
  - This is due to the way the new audio engine is designed.
- HTML5 export using asm.js.
  - Only WebAssembly is supported now, since all browsers supporting WebGL 2.0 also support WebAssembly.
