+
+### Changed
+
+- [Built-in vector types now use copy-on-write mode as originally intended](https://godotengine.org/article/why-we-broke-your-pr), resulting in increased engine performance.
+- The [mbedtls](https://tls.mbed.org/) library is now used instead of OpenSSL.
+- SSL certificates are now bundled in exported projects unless a custom bundle is specified.
+- Improved buffer writing performance on Windows and Linux.
+- Removed many debugging prints in the console.
+- Export templates now display an error dialog if no project was found when starting.
+- DynamicFont oversampling is now enabled by default.
+- Nodes' internal logic now consistently use internal physics processing.
+- Allow attaching and clearing scripts on multiple nodes at once.
+- Default values are no longer saved in scene and resource files.
+- The selection rectangle of 2D nodes is now hidden when not pertinent (no more rectangle for collision shapes).
+- SSE2 is now enabled in libsquish, resulting in improved S3TC encoding performance.
+- Tangent and binormal coordinates are now more consistent across mesh types (primitive/imported), resulting in more predictable normal map and depth map appearance.
+- Better defaults for 3D scenes.
+  - The default procedural sky now has a more neutral blue tone.
+  - The default SpatialMaterial now has a roughness value of 1 and metallic value of 0.
+  - The fallback material now uses the same values as the default SpatialMaterial.
+- Text editor themes are now sorted alphabetically in the selection dropdown.
+- The 3D manipulator gizmo now has a smoother, more detailed appearance.
+- The 3D viewport menu button now has a background to make it easier to read.
+- Controls inside containers are no longer movable or resizable but can still be selected.
+- The `is` GDScript keyword can now be used to compare a value against built-in types.
+- Named enums in GDScript no longer create script constants.
+  - This means `enum Name { VALUE }` must now be accessed with `Name.VALUE` instead of `VALUE`.
+- Shadowing variables from parent scopes is no longer allowed in GDScript.
+- Function parameters' default values can no longer depend on other parameters in GDScript.
+- Indentation guides are now displayed in a more subtle way in the script editor.
+  - Indentation guides are now displayed when indenting using spaces.
+- Multi-line strings are now highlighted as strings rather than as comments in the script editor.
+  - This is because GDScript does not officially support multiline comments.
+- Increased the script editor's line spacing (4 pixels → 6 pixels).
+- Increased the caret width in the script editor (1 pixel → 2 pixels).
+- The project manager window is now resized to match the editor scale.
+- The asset library now makes use of threading, making loading more responsive.
+- Line spacing in the script editor, underlines and caret widths are now resized to match the editor scale.
+- Replaced editor icons for checkboxes and radio buttons with simpler designs.
+- Tweaked the editor's success, error, and warning text colors for better readability and consistency.
+- **Android:** Custom permissions are now stored in an array and their amount is no longer limited to 20.
+  - Custom permissions will have to be redefined in projects imported from older versions.
+- **Android:** Provide error details when an in-app purchase fails.
+- **Linux:** `OS.alert()` now uses Zenity or KDialog if available instead of xmessage.
+- **Mono:** Display stack traces for inner exceptions.
+- **Mono:** Bundle `mscorlib.dll` with Godot to improve portability.
+
+### Removed
+
+- **macOS:** Support for 32-bit and fat binaries.
+
+### Fixed
+
+- [`move_and_slide()` now behaves differently at low velocities](https://github.com/godotengine/godot/issues/21683), which makes it function as originally intended.
+- AnimatedSprite2D's `animation_finished` signal is now triggered at the end of the animation, instead of as soon as the last frame displays.
+- Audio buses can now be removed in the editor while they are used by AudioStreamPlayer2D/3D nodes.
+- Do not show the project manager unless no project was found at all.

+- Gizmos are now properly hidden on scene load if the object they control is hidden.
+- Camera gizmos in the 3D viewport no longer look twice as wide as they actually are.
+- Copy/pasting from the editor on X11 will now work more reliably.
+- `libgcc_s` and `libstdc++` are now linked statically for better Linux binary portability.
+- The FPS cap set by `force_fps` in the Project Settings is no longer applied to the editor.
+  - Low FPS caps no longer cause the editor to feel sluggish.
+- hiDPI is now detected and used if needed in the project manager.
+- The Visual Studio Code external editor option now recognizes more binary names such as `code-oss`, making detection more reliable.
+- The `-ffast-math` flag is no longer used when compiling Godot, resulting in increased floating-point determinism.
+- Fix spelling of `apply_torque_impulse()` and deprecate the misspelled method.
+- Remove spurious errors when using a PanoramaSky without textures.
+- The lightmap baker will now use all available cores on Windows.
+- Bullet physics now correctly calculates effective gravity on KinematicBodies.

+- Android exporter no longer writes unnecessary permissions to the exported APK.
+- Debugger "focus stealing" now works more reliably.
+- Subresources are now always saved when saving a scene.
+- Many fixes related to importers (glTF, Collada, audio), physics (Bullet), Mono/C#, GDNative, Android/iOS.
+- **Mono:** Many fixes and improvements to C# support (including a `[Signal]` attribute).
+- **WebAssembly:** Supply proper CORS headers.
+
+### Security
+
