(#5901) [@Teselka] - Misc: fixed compile-time detection of SSE features on MSVC 32-bits builds. (#5943) [@TheMostDiligent] +- Examples: DirectX10, DirectX11: try WARP software driver if hardware driver is not available. (#5924, #5562) - Backends: Allegro5: restoring using al_draw_indexed_prim() when Allegro version is >= 5.2.5. (#5937) [@Espyo] - Backends: Vulkan: Fixed sampler passed to ImGui_ImplVulkan_AddTexture() not being honored as we were using an immutable sampler.
