 ## [0.38.0] - 2024-04-01
 
 With over two years of collecting breaking changes (since the `0.37.0` release in March 2022), April 2024 marks the next breaking release of `ash`.  This release introduces an overhaul of all Vulkan structures, restructures modules around extensions, and separates extension wrappers between `Instance` and `Device` functions.  The crate contains all bindings defined by the latest `1.3.281` Vulkan specification, and many old and new extensions have received a hand-written extension wrapper.  For a full overview of all individual changes, see the list at the end of this post.
