Upgrading from Godot 4.3 to Godot 4.4
=====================================

For most games and apps made with 4.3 it should be relatively safe to migrate to 4.4.
This page intends to cover everything you need to pay attention to when migrating
your project.

Breaking changes
----------------

If you are migrating from 4.3 to 4.4, the breaking changes listed here might
affect you. Changes are grouped by areas/systems.

This article indicates whether each breaking change affects GDScript and whether
the C# breaking change is *binary compatible* or *source compatible*:

- **Binary compatible** - Existing binaries will load and execute successfully without
  recompilation, and the run-time behavior won't change.
- **Source compatible** - Source code will compile successfully without changes when
  upgrading Godot.

**Export annotations**

.. warning::

    The behavior of ``@export_file`` changed in Godot 4.4. When assigning a new value from the Inspector, the path is now stored and returned as a ``uid://`` reference instead of the traditional ``res://`` path. This is a **breaking change** and may cause issues if you're expecting ``res://``-based paths in scripts or serialized files.

    For example, exported arrays of files may now contain a mix of ``uid://`` and ``res://`` paths, especially if they were edited partially in the Inspector.

    In 4.4, the only way to retain the ``res://`` format is to **manually edit** the `.tscn` or `.tres` files in a text editor. Starting in Godot 4.5, a new annotation ``@export_file_path`` can be used to explicitly retain the old behavior and export raw ``res://`` paths.

Core
~~~~

.. note::

    The ``Curve`` resource now enforces its value range, so ``min_value`` and ``max_value`` need to be changed
    if any of the points fall outside of the default ``[0, 1]`` range.

Rendering
~~~~~~~~~

.. note::

    The ``VisualShaderNodeVec4Constant`` shader node had its input type changed to ``Vector4``. Users need to
    recreate the values in their constants.

CSG
~~~

.. note::

    The CSG implementation now uses Emmett Lalish's `Manifold <https://github.com/elalish/manifold>`_ library (`GH-94321`_).
    The new implementation is more consistent with manifold definitions and fixes a number of bugs and stability
    issues. As a result, non-manifold meshes are no longer supported. You can use ``MeshInstance3D`` for
    rendering non-manifold geometry, such as quads or planes.

Android
~~~~~~~

.. note::

    Android sensor events are no longer enabled by default (`GH-94799`_). Projects that use sensor events can
    enable them as needed in Project Settings under **Input Devices > Sensors**.
