Change log for January 05, 2019 Vulkan 1.1.97 spec update: * Update release number to 97. Public Issues: * Add a special case to the <<renderpass-compatibility, Render Pass Compatibility>> rules allowing single-subpass renderpasses to be compatible even if they have different resolve attachment references (public issue 835). * Fix the miss shader binding table record address rule in the <<shader-binding-table-indexing-rules, Miss Shaders>> section to index by code:missIndex, not code:sbtOffset (public issue 875). Internal Issues: * Add a missing anchor to the elink:VkSamplerCreateFlagBits language (internal issue 1483). * Add missing implicit valid usage include for slink:VkHdrMetadataEXT and corresponding `noautovalidity` attributes in `vk.xml` for the externally-defined metadata properties (internal issue 1514). * Remove restrictions on the `mask` parameter of SPIR-V's code:OpGroupNonUniformXor in the <<spirvenv-module-validation, Validation Rules within a Module>> appendix (internal merge request 2971). * Restore `noautovalidity` attribute for slink:VkPipelineViewportWScalingStateCreateInfoNV::pname:pViewportWScalings in `vk.xml` (internal merge request 2975). * Update copyright dates on Khronos-copyrighted files to 2019 (internal merge request 2980).

Change log for June 24, 2017 Vulkan 1.0.53 spec update: * Bump API patch number and header version number to 53 for this update. Github Issues: Internal Issues: * Clarify mappings of coordinates for mutable, compatible image views in slink:VkImageViewCreateInfo (internal issue 815). * Make ename:VK_BIND_SFR_BIT require a logical device with multiple physical devices, so that standard sparse image block dimensions are only required on systems that support multi-GPU (internal issue 835). * Convert all files from use of // refBegin .. // refEnd comments to delimit ref pages, to use of open blocks, and update style guide accordingly (internal issue 839). * Add valid usage for slink:VkWriteDescriptorSet when performing updates to a ename:VK_STORAGE_IMAGE descriptor with layout ename:VK_IMAGE_LAYOUT_GENERAL. * Add a hack to the validity generator script to support an odd interaction between flink:vkCmdFillBuffer and an extension (internal issue 853). * Remove redundant text describing slink:VkBufferCreateInfo::pname:usage, which was already covered by implicit valid usage (internal issue 854). * Update implicit validity generator script to properly handle the pname:sType and pname:pNext members of "returnedonly" structures (internal issue 874). * Note that slink:VkApplicationInfo::pname:pApplicationName & slink:VkApplicationInfo::pname:pEngineName are optional, and add missing implicit valid usage statements for flink:vkDestroyInstance. * Added missing valid usage for flink:vkCmdWriteTimestamp to require a timestamp query pool. * Simplify and/or split "`non-atomic`" valid usage statements. New Extensions: * `VK_AMD_gpu_shader_int16` * `VK_EXT_blend_operation_advanced` * `VK_EXT_sampler_filter_minmax` * `VK_NV_framebuffer_mixed_samples` ----------------------------------------------------- Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release combines both change sets. ----------------------------------------------------- Change log for June 13, 2017 Vulkan 1.0.52 spec update: * Bump API patch number and header version number to 52 for this update. Github Issues: Internal Issues: * Clarify behavior when non-coherent memory has <<memory-device-unmap-does-not-flush, not been flushed before being unmapped>> (internal issue 819). * Fix description of code:WorkgroupSize builtin to note it decorates an object, not a variable (internal issue 836). * Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style equations are rendered properly (internal issue 845). * Add language to the "`Extension Handles, Objects, Enums, and Typedefs`" section of the Procedures and Conventions document stating that any new handle type requires a corresponding entry in the elink:VkObjectType enumerated type (internal issue 856). * Update style guide to use slink macro for Vulkan handle type names, and define narrow conditions under which to use the *name and *text macros instead of *link (internal issue 886). * Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>> extension on VK_KHX_device_group_creation to +vk.xml+ and the extension appendix. * Change the copyright on Vulkan specification asciidoc *source* files to CC-BY 4.0, and update the proprietary Khronos copyright applied to the generated *output* formats (internal issue 327). This enables broader re-use and modification of the Vulkan specification sources, while not affecting the Reciprocal IP License between Vulkan Adopters and Working Group Members. New Extensions: * `VK_NV_fill_rectangle` * `VK_NV_fragment_coverage_to_color`

Change log for September 5, 2017 Vulkan 1.0.60 spec update: * Bump API patch number and header version number to 60 for this update. Github Issues: * Document that <<queries-timestamps, Timestamp Queries>> can only be meaningfully compared when they are written from the same queue (public issue 216). * Document that the `<extension>` tag `type` attribute is required for non-disabled extensions (derived from, but does not close public issue 354). * Clean up registry schema length attribute descriptions to be consistent and correct (public issue 555). Internal Issues: * Replace as much of the hand-written extension appendix metadata as possible with asciidoc includes generated from corresponding attributes of +vk.xml+, and enhance the style guide to match. This avoids inconsistencies between +vk.xml+ and the appendices, and produces a more uniform style (internal issue 137). * Remove the generated extDependency.{py,sh} files from the tree and create them dynamically on demand instead, reducing merge conflicts (internal issue 713). * Add a prototype tool for generating in-place difference markup for sections guarded by asciidoc conditionals, and new syntax for open blocks to support it (internal issue 833). * Remove unnecessary restriction of etext:*SYNC_FD_BIT_KHR external handle types to the same physical device in the slink:VkPhysicalDeviceIDPropertiesKHR, flink:VkImportMemoryWin32HandleInfoKHR, slink:VkImportFenceWin32HandleInfoKHR, slink:VkImportFenceFdInfoKHR, slink:VkImportSemaphoreWin32HandleInfoKHR, slink:VkImportSemaphoreFdInfoKHR <<external-memory-handle-types-compatibility, External memory handle types compatibility>>, <<external-semaphore-handle-types-compatibility, External semaphore handle types compatibility>>, and <<external-fence-handle-types-compatibility, External fence handle types compatibility>> sections (internal issue 956). Other Issues: * Remove dependency of +VK_KHX_device_group+ on +VK_KHR_swapchain+ (there is an interaction, but not a strict dependency), and add a new `extension` attribute to the `<require` XML tag to allow classifying a subset of interfaces of an extension as requiring another extension. Update the registry schema and documentation accordingly. New Extensions: * `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask` GLSL extension) * `VK_EXT_sample_locations` * `VK_EXT_validation_cache`

An application can use this to minimize various visual anomalies (e.g.
stuttering).
Traditional game and real-time animation applications need to correctly
position their geometry for when the presentable image will be presented to
the user.
To accomplish this, applications need various timing information about the
presentation engine's display.
They need to know when presentable images were actually presented, and when
they could have been presented.
Applications also need to tell the presentation engine to display an image
no sooner than a given time.
Fix random grammar

This allows the application to avoid stuttering, so the animation looks
smooth to the user.
