 - Customization and integration with custom engines: Predefine appropriate macros to provide your own implementation of external facilities used by the library, like assert, mutex, and atomic.
 - Support for resource aliasing (overlap).
 - Custom memory pools: Create a pool with desired parameters (e.g. fixed or limited maximum size, custom `D3D12_HEAP_PROPERTIES` and `D3D12_HEAP_FLAGS`) and allocate memory out of it.
+- Support for GPU Upload Heaps from preview Agility SDK (needs compilation with `D3D12MA_OPTIONS16_SUPPORTED` macro).
 - Linear allocator: Create a pool with linear algorithm and use it for much faster allocations and deallocations in free-at-once, stack, double stack, or ring buffer fashion.
 - Defragmentation: Let the library move data around to free some memory blocks and make your allocations better compacted.
 - Statistics: Obtain brief or detailed statistics about the amount of memory used, unused, number of allocated heaps, number of allocations etc. - globally and per memory heap type. Current memory usage and budget as reported by the system can also be queried.

-As you can see, {fmt} has 60% less overhead in terms of resulting binary
-code size compared to iostreams and comes pretty close to `printf`.
-Boost Format and Folly Format have the largest overheads.
-
-`printf+string` is the same as `printf` but with an extra `<string>`
-include to measure the overhead of the latter.
+{fmt} is fast to compile and is comparable to `printf` in terms of per-call
+binary size (within a rounding error on this system).
