 ## Updates
 
+#### 30-Oct-2023
+
+Some sokol_gfx.h backend-specific updates and tweaks (very minor chance that this is breaking):
+
+- a new set of public API functions to access the native backend 3D-API resource objects of
+  sokol-gfx resource objects:
+
+  ```
+  sg_[api]_[type]_info sg_[api]_query_[type]_info(sg_[type])
+  ```
+  ...where `[api]` is any of `[gl, d3d11, mtl, wgpu]` and `[type]` is any of `[buffer, image, sampler, shader, pipeline, pass]`.
+
+  This is mainly useful when mixing native 3D-API code with sokol-gfx code.
+
+  See issue https://github.com/floooh/sokol/issues/931 for details.
+
+- WebGPU backend: `sg_make_image()` will no longer automatically create a WebGPU texture-view object when injecting a WebGPU texture object, instead
+this must now be explicitly provided.
+
+- D3D11 backend: `sg_make_image()` will no longer automatically create a
+shader-resource-view object when injecting a D3D11 texture object, and
+vice versa, a texture object will no longer be looked up from an injected
+shader-resource-view object (e.g. the injection rules are now more straightforward and explicit). See issue https://github.com/floooh/sokol/issues/930 for details.
+
+For the detailed changes, see PR https://github.com/floooh/sokol/pull/932.
