+======================================================================================================================== =================== ==================== ==================== =========== + +Behavior changes +---------------- + +In 4.3 some behavior changes have been introduced, which might require you to adjust your project. + +Core +^^^^ + +.. note:: + + Binary serialization was modified to fix some issues with the serialization of scripted Objects and typed Arrays (`GH-78219`_). + This breaks compat with script encoding/decoding. + +.. note:: + + ``PackedByteArray`` is now encoded as a base64 string, this breaks compatibility in resources that contain them + making them no longer usable in older versions of the engine (`GH-89186`_). + +.. note:: + + In C#, the ``Transform3D.InterpolateWith`` implementation was fixed to use the right order of operations, applying the rotation before the scale (`GH-89843`_). + +.. note:: + + In C#, the ``Aabb.GetSupport`` implementation was fixed to properly return the support vector (`GH-88919`_). + +.. note:: + + In C#, the Variant types' ``ToString`` implementation now defaults to using the ``InvariantCulture`` (`GH-89547`_) + which means ``Vector2(1.2, 3.4)`` is formatted using ``.`` as the decimal separator independently of the language + of the operating system that the program is running on. + +Animation +^^^^^^^^^ + +.. note:: + + ``AnimationMixer`` replaced its Capture mode with a new Capture feature that works much better than the old one, + this replaces the existing cache (`GH-86715`_). + +.. note:: + + ``AnimationNode`` has a reworked process for retrieving the semantic time info. This ensures that time-related + behavior works as expected, but changes the blending behavior. Implementors of the ``_process`` virtual method + should also note that this method is now deprecated and will be replaced by a new one in the future (`GH-87171`_). + +GUI nodes +^^^^^^^^^ + +.. note:: + + The default font outline color was changed from white to black. (`GH-54641`_). + +.. note:: + + The ``auto_translate`` property is deprecated in favor of the ``auto_translate_mode`` property which is now in ``Node`` (`GH-87530`_). + Existing nodes that with ``auto_translate`` enabled may no longer be translated if their parent does not enable ``auto_translate``. + +Rendering +^^^^^^^^^ + +.. note:: + + Decals now convert the modulate color from an sRGB color to a linear color, like all other inputs, to ensure proper + blending (`GH-89849`_). Existing projects that were using the decal's modulate property will notice a change in + their visuals. + +TileMap +^^^^^^^ + +.. note:: + + ``TileMap`` layers were moved to individual nodes (`GH-87379`_ and `GH-89179`_). + +.. |❌| replace:: :abbr:`❌ (This API breaks compatibility.)` +.. |✔️| replace:: :abbr:`✔️ (This API does not break compatibility.)` +.. |✔️ with compat| replace:: :abbr:`✔️ (This API does not break compatibility.
