+##### Split up `Features` internally
+
+Internally split up the `Features` struct and recombine them internally using a macro. There should be no breaking 
+changes from this. This means there are also namespaces (as well as the old `Features::*`) for all wgpu specific
+features and webgpu feature (`FeaturesWGPU` and `FeaturesWebGPU` respectively) and `Features::from_internal_flags` which
+allow you to be explicit about whether features you need are available on the web too.

 ##### Refactored internal trace path parameter
 
 Refactored some functions to handle the internal trace path as a string to avoid possible issues with `no_std` support.
