 ## v0.00.005 - Z layers
+
 Renderer:
 	- Added optional Z-sorting
 		- Either set quad->z or call push_z_layer(s64) (and pop_z_layer())
 		- Enable with draw_frame.enable_z_sorting = true
 	- Refactored the quad buffering to just be a growing quad buffer rather than a linked list of quad blocks. Your CPU will be thankful.
+	- Fixed crashing when D3D11 DEBUG flag fails in ID3D11CreateDevice, and instead log a descriptive error then continue as usual
 	
 Misc:
 	- removed gfx_impl_legacy_opengl.c
