 - Misc: Debuggers: added type formatters for the LLDB debuggers (e.g. Xcode,
   Android Studio & more) to provide nicer display for ImVec2, ImVec4, ImVector etc.
   See misc/debuggers/ for details. (#8950) [@mentlerd]
+- CI: Updates Windows CI scripts to generate/use VulkanSDK. (#8925, #8778) [@yaz0r]
 - Backends: all backends call ImGuiPlatformIO::ClearPlatformHandlers() and
   ClearRendererHandlers() on shutdown, so as not to leave function pointers
   which may be dangling when using backend in e.g. DLL. (#8945, #2769)
