@@ -64,6 +64,9 @@ Changes to `DescriptorPool`:
 Changes to pipeline caches:
 - They are now constructed with the standard combination of a `new` constructor and a `PipelineCacheCreateInfo`.
 
+Changes to `Swapchain`:
+- Swapchain creation no longer returns an error when the swapchain extent doesn't match the current surface extent. This requirement is ill-defined in the spec, as detailed here: [TOCTOU race condition on minImageExtent/maxImageExtent?](https://github.com/KhronosGroup/Vulkan-Docs/issues/1144).

 ### Additions
 
 - Vulkano-shaders: Added a `root_path_env` property to allow loading shaders generated by a build script.

 - Support for the `khr_device_group_creation` extension.
 - Added support for `InlineUniformBlock` descriptors.
 - When creating an instance or device, you only need to specify the extensions and features you actually care about. Any extensions and features that are required by the extensions that you specified are now automatically enabled too.
+- Support for the `ext_surface_maintenance1` and most of the `ext_swapchain_maintenance1` extension.
