// [ ] Renderer: Use of DrawCallback_SetSamplerLinear, DrawCallback_SetSamplerNearest is emulated by poking to glTexParameter(), as legacy OpenGL doesn't have glBindSampler().

Breaking Changes:
- DrawList:
- Obsoleted `ImDrawCallback_ResetRenderState` in favor of using `ImGui::GetPlatformIO().DrawCallback_ResetRenderState`,
which is part of our new standard draw callbacks. (#9378)
Redirecting the earlier value into the later one when set, so both old and new code should work.
- Backends:
- Vulkan: redesigned to use separate ImageView + Sampler instead of Combined Image Sampler. (#914)
This change allows us to facilitate changing samplers, in line with other backends. [@yaz0r, @ocornut]
- When creating your own descriptor pool (instead of letting backend creates its own):
- Before: need at least IMGUI_IMPL_VULKAN_MINIMUM_IMAGE_SAMPLER_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER.
- After: need at least IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE.
+ IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLER.
- When registering custom textures: changed ImGui_ImplVulkan_AddTexture() signature to remove Sampler.
- Before: ImGui_ImplVulkan_AddTexture(VkSampler, VkImageView, VkImageLayout)
- After: ImGui_ImplVulkan_AddTexture(VkImageView, VkImageLayout)
- Kept inline redirection function that ignores the sampler (will obsolete).
- DirectX10, DirectX11, SDLGPU3, Vulkan: removed samplers from ImGui_ImplXXXX_RenderState.
Prefer to use backend-agnostic DrawCallback_SetSamplerLinear which works everywhere! (#9378)
If there is a legit need/request for them or any render state we can always add them back.
Other Changes:
- DrawList:
- Added room in ImGuiPlatformIO for standard backend-agnostic draw callbacks. Those callbacks
are setup/provided by the backend and available in most of our standard backends.
They allow backend-agnostic code from e.g. switching to a Nearest/Point sampler without
messing with custom Renderer-specific callbacks.
platform_io.DrawCallback_ResetRenderState; // Request to reset the graphics/render state.
platform_io.DrawCallback_SetSamplerLinear; // Request to set current texture sampling to Linear
platform_io.DrawCallback_SetSamplerNearest; // Request to set current texture sampling to Nearest/Point
Note that some backends might not support all callbacks.

When you are not sure about an old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files.
You can read releases logs https://github.com/ocornut/imgui/releases for more details.
- 2026/04/23 (1.92.8) - Obsoleted `ImDrawCallback_ResetRenderState` in favor of using `ImGui::GetPlatformIO().DrawCallback_ResetRenderState`, which is part of our new standard draw callbacks. (#9378)
- 2026/04/22 (1.92.8) - Backends: Vulkan: redesigned to use separate ImageView + Sampler instead of Combined Image Sampler.
- When registering custom textures: changed ImGui_ImplVulkan_AddTexture() signature to remove Sampler.
- When creating your own descriptor pool (instead of letting backend creates its own): need at least IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE + IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLER.
- 2026/03/19 (1.92.7) - MultiSelect: renamed ImGuiMultiSelectFlags_SelectOnClick to ImGuiMultiSelectFlags_SelectOnAuto.
- 2026/02/26 (1.92.7) - Separator: fixed a legacy quirk where Separator() was submitting a zero-height item for layout purpose, even though it draws a 1-pixel separator.
The fix could affect code e.g. computing height from multiple widgets in order to allocate vertical space for a footer or multi-line status bar. (#2657, #9263)
