#### Core

- Removed the YSort node in favor of the Node2D YSort property.
- Removed the deprecated `Color.gray()` method.
  - Use `Color.v()` for a better grayscale approximation instead.
- Removed built-in HQ2X implementation (used for crude hiDPI support in the default project theme).
  - This helps with binary size as HQ2X is made of particularly large functions.

#### Editor

- Removed the **Dim Dialog on Editor Popup** editor setting since it was made obsolete by the multi-window paradigm.

#### Physics

- Removed the deprecated PhysicsBody `friction` and `bounce` properties (replaced by PhysicsMaterial).

#### Rendering

- Removed OpenGL ES 2.0 renderer (replaced by the new mobile-oriented OpenGL 3 renderer).

- [Removed support for 16× MSAA due to driver bugs and low performance.](https://github.com/godotengine/godot/pull/49063)
  - For high-quality offline rendering, using supersampling together with 8× MSAA is a better option anyway.

### Fixed

#### Core

- The positional command line argument now considers `.res` and `.tres` files as runnable scene formats.
  - This fixes Godot not running the main scene or a custom scene if they were saved with a `.res` or `.tres` extension.
- **macOS/Linux:** Fix the result of `Directory.get_space_left()`.
- **Windows:** Godot can now kill its own PID using `OS.kill()`.

#### Editor

- The Android exporter no longer reports progress on each file, greatly speeding up the exporting process.
- Searching with the Whole Words option enabled in the script editor is no longer exceedingly slow.

#### GUI

- Fixed OptionButton minimum size.
- TabContainer is no longer too large when tabs are hidden.
- ScrollBar now allows using `scroll_to_line()` when Scroll Active is disabled.
- DynamicFont outlines now have antialiasing disabled if it was disabled on the font itself.

#### Porting

### Changed

- Tween and Timer now display an error message if they are started without being added to the scene tree first.
- Tweaked Timer's wait time property hint to allow values with 3 decimals and above 4096.
- Functions called from a signal can no longer disconnect the node from the signal they're connected to (unless using `call_deferred()`).
- Tabs and space indentation can no longer be mixed in the same GDScript file.
  - Each file must now use only tabs or spaces for indentation (not both).
- `assert()` in GDScript must now always be used with parentheses.
  - `assert(true)` is still valid, but `assert true` isn't valid anymore.
  - This is to account for the optional second parameter that defines a custom message.
- The "Trim" and "Normalize" WAV import options are now disabled by default.
  - This makes the default behavior more consistent with Ogg import.
- Ogg samples now have an icon in the editor, like WAV samples.
- Camera2D drag margins are now disabled by default.
  - If porting a project from Godot 3.1 where drag margins were used, these must be enabled manually again.
- The Camera2D Offset property now ignores the Limit property.
  - To get the old behavior back, move the camera itself instead of changing the offset.
- `Camera.project_position()` now requires a second `depth` argument to determine the distance of the point from the camera.
  - To get the old behavior back, pass the Camera's `near` property value as the second argument.
- `Skeleton.set_bone_global_pose()` was replaced by `Skeleton.set_bone_global_pose_override()`.
- UDP broadcasting is now disabled by default and must be enabled by calling `set_broadcast_enabled(true)` on the PacketPeerUDP instance.
- The editor and project manager now open slightly faster.
- Improved the Project Manager user interface.
  - New, simpler design with more space available for the project list.
  - Improved reporting of missing projects.
  - The search field is now focused when starting the Project Manager if there is at least one project in the list.
  - The search field now searches in both the project name and path.
    - If the search term contains a `/`, the whole path will be used to match the search them. Otherwise, only the last path component will be searched in.
- Refactored the Project Manager to be more efficient, especially with large project lists.
- Images in the Project Manager and Asset Library are now resized with Lanczos filtering for a smoother appearance.
- The editor now uses the font hinting algorithm that best matches the OS' default.
  - Hinting is set to "None" on macOS, and set to "Light" on Windows and Linux.
  - This can be changed in the Editor Settings.
- The editor window dimming when a popup appears is now less intense (60% → 50%).
  - The animation was also removed as it made the editor feel sluggish at lower FPS.
- Several editor menus have been reorganized for consistency and conciseness.
- Undo/Redo now supports more actions throughout the editor.
- Increased the height of the ItemList editor popup.
  - This makes it easier to edit large amounts of items.

- Improved A* performance significantly by using a binary heap and OAHashMap.
- Tweaked the AABB transform algorithm to be ~1.2 times faster.
- Optimized the variant reference function, making complex scripts slightly faster.
- Disabled high-quality voxel cone tracing by default.
  - This makes GIProbe much faster out of the box, at the cost of less realistic reflections.
- Lowered the default maximum directional shadow distance (200 → 100).
  - This makes directional shadow rendering consistent between the editor and running project when using the default Camera node settings.
- Tweaked the default depth fog maximum distance to be independent of the Camera's `far` value (0..100).
  - This makes fog display consistent between the editor and a running project.
- Tweaked the default height fog values to be more logical (0..100 → 10..0).
  - This means height fog will be drawn from top-to-bottom, instead of being drawn from bottom-to-top.
- Significantly improved SSAO performance by using a lower sample count.

- The StyleBox preview now accounts for shadows and content margins.
  - This fixes the preview going out of bounds in the inspector.
- Text resources no longer contain an extraneous line break at the end of file.
- Transform's `FLIP_Y` and `FLIP_Z` constants now work as expected.
- Fixed importing BMP images.
- The positional command-line argument is now only considered to be a scene path if it ends with `.scn`, `.tscn` or `.escn`.
  - This makes it possible to parse command-line arguments in a standard fashion (`--foo bar` now works, not just `--foo=bar`).
  - This also makes it possible to use file associations or drag-and-drop and have the positional argument parsed by the project.
- The `--audio-driver` and `--video-driver` command-line arguments are now validated; an error message will be printed if an invalid value is passed.
- The `--check-only` command-line argument now returns a non-zero exit code if an invalid script is passed using `--script`.
- Exporting a project via the command-line now returns a non-zero exit code if an error occurred during exporting.
- Console output is no longer colored when standard output isn't a TTY.
  - This prevents Godot from writing ANSI escape codes when redirecting standard output or standard error to a file.

- **HTML5:** `OS.get_system_time_msec()` now returns the correct value like on other platforms.
- **iOS:** On iOS 11 or later, gestures near screen edges are now handled by Godot instead of the OS.
- **Windows:** Line endings are now converted to CRLF when setting clipboard content.
- **Windows:** Getting the path to the Downloads directory using `OS.get_system_dir()` now works correctly.
  - This fixes line endings being invisible when pasting into other applications.
- **macOS:** `OS.get_real_window_size()` and `OS.set_window_size()` are now handled correctly on hiDPI displays.
- **X11:** `OS.get_window_position()` now returns absolute coordinates.
