 #### New `EXPERIMENTAL_PRECOMPILED_SHADERS` API
+
 We have added `Features::EXPERIMENTAL_PRECOMPILED_SHADERS`, replacing existing passthrough types with a unified `CreateShaderModuleDescriptorPassthrough` which allows passing multiple shader codes for different backends.

 Difference for SPIR-V passthrough:

 ```
 This allows using precompiled shaders without manually checking which backend's code to pass, for example if you have shaders precompiled for both DXIL and SPIR-V.
 
+#### Buffer mapping apis no longer have lifetimes
+
+`Buffer::get_mapped_range()`, `Buffer::get_mapped_range_mut()`, and `Queue::write_buffer_with()` now return guard objects without any lifetimes. This
+makes it significantly easier to store these types in structs, which is useful for building utilities that build the contents of a buffer over time.

 #### `EXPERIMENTAL_*` features now require unsafe code to enable
 
 We want to be able to expose potentially experimental features to our users before we have ensured that they are fully sound to use.
