### 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.

  - This means height fog will be drawn from top-to-bottom, instead of being drawn from bottom-to-top.

  - Lower and higher values can be entered manually too.

  - Lower and higher values can still be entered manually, which is useful for animation purposes.
- The default RichTextLabel color is now `#ffffff`, matching the default Label color for better consistency.
- SpinBoxes now calculate the entered value using the Expression class.
  - For example, writing `2 + 2` in a SpinBox then pressing Enter will result in `4`.

- The script editor's line length guideline is now drawn at the correct position when font hinting is disabled.
- The script editor now automatically indents a line if the previous one ends with `[` or `(`.
  - This makes it possible to wrap arrays or function declarations/calls without pressing <kbd>Tab</kbd> every line.

- Documentation tooltips in the editor now wrap to multiple lines correctly.

- The random number generator's seed is now properly set up.
- Antialiased and rounded StyleBoxFlat corners now handle different border widths correctly.
- 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.
- **Android:** Gamepads are now correctly detected when the application starts.
- **Android:** Fix some keyboards being detected as gamepads and not working as a result.
- **Android:** The editor now detects if the device is connected using wireless `adb` and will debug using Wi-Fi in this case.
- **HTML5:** Fixed the pointer position on hiDPI displays.
- **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.
- **X11:** Fixed audio playing on the wrong speakers when using PulseAudio on 5.1 setups.
- **X11:** `OS.set_window_maximized()` now gives up after 0.5 seconds.
  - This makes the editor no longer freeze on startup when using fvwm.
