+# Material Maker 1.4a1
+
+## Known problems
+
+- User settings are saved in a different directory (so using 1.4 alphas should not
+  affect your 1.3 configuration)
+- Subwindows are not scaled correctly if the UI scale is not 1
+
+## General
+
+- Added flexible UI layout: panels can be moved anywhere in the window or
+  undocked (Material authoring and Painting have different layouts)
+- Improved theme support (especially made many custom UI components themeable),
+  added a new Modern theme and improved old themes (contributed by Jowan-Spooner)
+- Added basic support for GLTF 3D models
+- Dropping a .obj or .glb file into the 3D preview panel will use it as preview model
+- In the 3D preview replaced the default cube mesh with a chamfered cube and the
+  plane with a bent plane (chamfer and curvature can be modified in the mesh
+  configuration popup)
+- Improved the Add Node popup so it's themeable, more performant and has better search
+  capabilities (contributed by Jowan-Spooner)
+- Improved the Library panel's design (contributed by Jowan-Spooner)
+- Added an editor for polygon parameters in the 2D preview
+- Added a shader error diagnostic tool
+- Added easy stylus pressure configuration in painting tool
+- Added a Find/Replace tool to code editor
+- Added an option to delete rescued unsaved projects at startup
+- Added support for hover copy+paste on float, color and gradient editors
+
+## Nodes
+
+- Added a MeshMap node that automatically bakes maps (position, normal, tangent,
+  curvature, occlusion or thickness) for the current custom mesh.
+- Added many new 2D and 3D SDF nodes (contributed by Theaninova and williamchange)
+- Added new operations to the Math and Vec3 Math nodes (contributed by williamchange)
+- Added a Shard FBM noise node (contributed by williamchange)
+- Added a Tex3D Uniform node (contributed by williamchange)
+- Added Classic, Generalized and Anisotropic Kuwahara filter nodes (contributed by williamchange)
+- Redesigned the Float and Gradient parameter editor widgets (contributed by Jowan-Spooner)
+- Improved the image picker UI (contributed by Jowan-Spooner)
+- Added a new Splines parameter type (that can be edited in the 2D preview directly)
+  and a new Splines node
+- Added a new Pixels parameter type, that can describe tiny images with 2, 4, 8 or 16 colors,
+  and can be edited in the 2D preview directly. Added new Pixels and Smooth Pixels nodes
+- Added a new Lattice parameter type and a new Distort node
+- Added a new Webcam node that can output a Webcam feed (MacOS only)
+- Added a density input to the Noise node
+- The 2D and 3D SDF Boolean and Transform nodes, the 3D SDF Color node and the
+  Tex3D Transform, Blend Select and Shape Select nodes are now variadic (contributed by williamchange)
+- The Blend node now has Hue, Saturation, Color and Value blend modes (contributed
+  by williamchange)
+- The Spherize node has been improved (contributed by williamchange)
+- Updated documentation for many nodes (contributed by williamchange)
+ 
+## Bug Fixes
+
+- Small fixes in the GLSL parser
+- Optimized polygon/polyline parameter
+
+## Miscellaneous
+
+- Material Maker is now based on Godot 4.3. While porting to Godot 4, many features
+  have been rewritten completely, including shader code generation and shader rendering
+- The MacOS export has been modified so Material Maker can be installed
+  easily (contributed by williamchange)
