Fix release for 1.1.1: the minimal path end to end, engine commands that run on Godot, Unity and Unreal, hook warnings you can see, and verdicts that say when they could not check. Details in CHANGELOG.md; upgrade steps in UPGRADING.md (v1.1.1 → v1.1.2). Fixes #67 Fixes #131 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WuJn2FdynEybfL5KC697nJ

# Godot — Breaking Changes
|
|
|
|
Last verified: 2026-02-12
|
|
|
|
Changes between Godot versions, focused on post-LLM-cutoff changes (4.4+).
|
|
|
|
## 4.5 → 4.6 (Jan 2026 — POST-CUTOFF, HIGH RISK)
|
|
|
|
| Subsystem | Change | Details |
|
|
|-----------|--------|---------|
|
|
| Physics | Jolt is now the DEFAULT 3D physics engine | New projects use Jolt automatically. Existing projects keep their setting. Some HingeJoint3D properties (like `damp`) only work with GodotPhysics. |
|
|
| Rendering | Glow processes BEFORE tonemapping | Was after tonemapping. Scenes with glow will look different. Adjust intensity/blend in WorldEnvironment. |
|
|
| Rendering | D3D12 default on Windows | Was Vulkan. For better driver compatibility. |
|
|
| Rendering | AgX tonemapper new controls | White point and contrast parameters added. |
|
|
| Core | Quaternion initializes to identity | Was zero. Unlikely to affect most code but technically breaking. |
|
|
| UI | Dual-focus system | Mouse/touch focus now separate from keyboard/gamepad focus. Visual feedback differs by input method. |
|
|
| Animation | IK system fully restored | CCDIK, FABRIK, Jacobian IK, Spline IK, TwoBoneIK via SkeletonModifier3D nodes. |
|
|
| Editor | New "Modern" theme default | Grayscale replaces blue-tint. Restore: Editor Settings → Interface → Theme → Style: Classic |
|
|
| Editor | "Select Mode" keybind changed | New "Select Mode" (v key) prevents accidental transforms. Old mode renamed "Transform Mode" (q key). |
|
|
| 2D | TileMapLayer scene tile rotation | Scene tiles can now be rotated like atlas tiles. |
|
|
| Localization | CSV plural form support | No longer requires Gettext for plurals. Context columns added. |
|
|
| C# | Automatic string extraction | Translation strings auto-extracted from C# code. |
|
|
| Plugins | New EditorDock class | Specialized container for plugin docks with layout control. |
|
|
|
|
## 4.4 → 4.5 (Late 2025 — POST-CUTOFF, HIGH RISK)
|
|
|
|
| Subsystem | Change | Details |
|
|
|-----------|--------|---------|
|
|
| GDScript | Variadic arguments added | Functions can accept `...` arbitrary params — new language feature |
|
|
| GDScript | `@abstract` decorator | Abstract classes and methods now enforceable |
|
|
| GDScript | Script backtracing | Detailed call stacks available even in Release builds |
|
|
| Rendering | Stencil buffer support | New capability for advanced visual effects |
|
|
| Rendering | SMAA 1x antialiasing | New post-processing AA option |
|
|
| Rendering | Shader Baker | Pre-compiles shaders — reportedly 20x faster startup on some demos |
|
|
| Rendering | Bent normal maps, specular occlusion | New material features |
|
|
| Accessibility | Screen reader support | Control nodes work with accessibility tools via AccessKit |
|
|
| Editor | Live translation preview | Test GUI layouts in different languages in-editor |
|
|
| Physics | 3D interpolation rearchitected | Moved from RenderingServer to SceneTree. API unchanged but internals differ. |
|
|
| Animation | BoneConstraint3D | New: AimModifier3D, CopyTransformModifier3D, ConvertTransformModifier3D |
|
|
| Resources | `duplicate_deep()` added | New explicit method for deep duplication of nested resources |
|
|
| Navigation | Dedicated 2D navigation server | No longer a proxy to 3D navigation; smaller export for 2D games |
|
|
| UI | FoldableContainer node | New accordion-style container for collapsible UI sections |
|
|
| UI | Recursive Control behavior | Disable mouse/focus interactions across entire node hierarchies |
|
|
| Platform | visionOS export support | New platform target |
|
|
| Platform | SDL3 gamepad driver | Delegated gamepad handling to SDL library |
|
|
| Platform | Android 16KB page support | Required for Google Play targeting Android 15+ |
|
|
|
|
## 4.3 → 4.4 (Mid 2025 — NEAR CUTOFF, VERIFY)
|
|
|
|
| Subsystem | Change | Details |
|
|
|-----------|--------|---------|
|
|
| Core | `FileAccess.store_*` return `bool` | Was `void`. Methods: `store_8`, `store_16`, `store_32`, `store_64`, `store_buffer`, `store_csv_line`, `store_double`, `store_float`, `store_half`, `store_line`, `store_pascal_string`, `store_real`, `store_string`, `store_var` |
|
|
| Core | `OS.execute_with_pipe` | Added optional `blocking` parameter |
|
|
| Core | `RegEx.compile/create_from_string` | Added optional `show_error` parameter |
|
|
| Rendering | `RenderingDevice.draw_list_begin` | Many parameters removed; `breadcrumb` parameter added |
|
|
| Rendering | `Shader.set_default_texture_parameter()` / `get_default_texture_parameter()` | Parameter/return type changed from `Texture2D` to `Texture`; the shading language did not change |
|
|
| Particles | `.restart()` method | Added optional `keep_seed` parameter (CPU/GPU 2D/3D) |
|
|
| GUI | `RichTextLabel.push_meta` | Added optional `tooltip` parameter |
|
|
| GUI | `GraphEdit.connect_node` | Added optional `keep_alive` parameter |
|
|
|
|
## 4.2 → 4.3 (In Training Data — LOW RISK)
|

|
|
|-----------|--------|---------|
|

|
|
| Animation | `bone_pose_updated` signal | Replaced by `skeleton_updated` |
|
|
| TileMap | `TileMapLayer` replaces `TileMap` | One node per layer instead of multi-layer single node |
|
|
| Navigation | `NavigationRegion2D` | Removed `avoidance_layers`, `constrain_avoidance` properties |
|
|
| Editor | `EditorSceneFormatImporterFBX` | Renamed to `EditorSceneFormatImporterFBX2GLTF` |
|
|
| Animation | AnimationMixer base class | AnimationPlayer and AnimationTree now extend AnimationMixer |
