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`

Change log for January 5, 2018 Vulkan 1.0.67 spec update: * Bump API patch number and header version number to 67 for this update. * Update copyright dates to 2018 Github Issues: * Fix texture lookup functions in `GL_KHR_vulkan_glsl` specification (public pull request 363). * Clarify the state waited semaphores are left in when a call to flink:vkQueuePresentKHR fails (public issue 572). * Cleanup descriptions of slink:VkObjectTablePushConstantEntryNVX and slink:VkObjectTableDescriptorSetEntryNVX (public issue 583) * Remove redundant flink:vkCmdSetDiscardRectangleEXT valid usage statements (public pull 586). * Make dynamic state array length valid usage statements implicit for flink:vkCmdSetViewportWScalingNV, flink:vkCmdSetDiscardRectangleEXT, and flink:vkCmdSetViewport (public pull 589). * Clarify meaning of window extent (0,0) in slink:VkSwapchainKHR for the Windows and X11 platforms, in their respective extensions (public issue 590). * Allow flink:vkGetPastPresentationTimingGOOGLE to return ename:VK_INCOMPLETE (public issue 604). * Add synchronization valid usage statements to flink:vkAcquireNextImage (public pull 611). * Fix some broken external links and internal xrefs (public pull 613). * Clean up slink:VkViewport valid usage statements in the presence or absence of relevant extensions (public pull 623). * Remove ename:VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_STENCIL_ATTACHMENT_OPTIMAL_KHR token from VK_KHR_maintenance2 from the non-extension VU path for slink:VkGraphicsPipelineCreateInfo (public issue 628). * Miscellaneous minor markup fixes - extension name strings (public pull 631), Notes (pull 633), queue names emitted by generator scripts (pull 634), block formatting in slink:VkDescriptorUpdateTemplateEntryKHR (pull 635), ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_CUBIC_BIT_IMG (pull 641), quotes and apostrophes (pull 643), * Miscellaneous minor grammar fixes (public pull 644). * Fix markup macros so usage like ptext:*Src* works (public pull 647). Internal Issues: * Clarify in the `VK_KHR_surface` and `VK_KHR_swapchain` extensions that parameter combinations which aren't supported for normal images are also unsupported for presentable images, even if the parameter values are individually supported as reported by the surface capability queries (internal issue 1029). * Fixed XML typo in the valid value field of the pname:sType member of slink:VkPhysicalDeviceExternalMemoryHostPropertiesEXT (internal issue 1100). Other Issues: * Add memory semantics validity rules to the <<spirvenv-module-validation, Validation Rules within a Module>> section of the SPIR-V environment appendix, and specify that sequentiality consistency is not supported. This forbids certain cases like "`Load+Release`" that we don't expect to ever be meaningful. * Document mapping of OpenGL Shading Language barriers to SPIR-V scope and semantics in the `GL_KHR_vulkan_glsl` specification. New Extensions: * `VK_EXT_conservative_rasterization`

An application using external memory may wish to synchronize access to that
memory using fences.
This extension enables an application to export fence payload to and import
fence payload from Windows handles.

`<<VK_KHR_external_semaphore_win32>>`.
That extension's issues apply equally to this extension.
1) Should D3D12 fence handle types be supported, like they are for
semaphores?
*RESOLVED*: No.
Doing so would require extending the fence signal and wait operations to
provide values to signal / wait for, like sname:VkD3D12FenceSubmitInfoKHR
does.
Change log for November 12, 2018 Vulkan 1.1.92 spec update: * Update release number to 92. Public Issues: * Move and modify valid usage statements dealing with pname:aspectMask in flink:vkCmdClearColorImage, flink:vkCmdClearDepthStencilImage, and slink:VkClearAttachment, so they are in places where all necessary information is available (public issue 529). * Fix math markup in <<textures-texel-anisotropic-filtering, Texel Anisotropic Filtering>> (public pull request 840). * Fix misspellings (public pull request 845). Internal Issues: * Add installation instructions and a Makefile "`chunked`" target for chunked HTML generation (internal issue 1352). * Fix pipeline mesh diagram style; also fix a minor bug in the classic pipeline diagram where vertex/index buffers wrongly fed into the vertex shader (internal issue 1436). * Make asciidoctor ERROR output raise an error, and don't suppress executed command output from CI make invocation (internal issue 1454). * Minor typo fixes and clarifications for `VK_NV_raytracing`. * Cleanup extension-specific properties ** Remove duplicated documentation for pname:maxDiscardRectangles, pname:pointClippingBehavior, and pname:maxVertexAttribDivisor (they shouldn't be documented with the other members of slink:VkPhysicalDeviceLimits at all). ** Remove duplicate anchor for pname:maxVertexAttribDivisor ** Consistently document stext:VkPhysicalDevice<Extension>PropertiesKHR *** Always document pname:sType/pname:pNext (was inconsistent before) *** Always mention chaining to slink:VkPhysicalDeviceProperties2 (and not as slink:VkPhysicalDeviceProperties2KHR) *** Always include Valid Usage statements last * Update Makefile 'checklinks' target and associated scripts, and fix markup problems identified by checkLinks.py, so that we can rely on the checklinks script as part of Gitlab CI.

A D3D12 fence can be signaled by importing it into a slink:VkSemaphore
instead of a slink:VkFence, and applications can check status or wait on the
D3D12 fence using non-Vulkan APIs.
The convenience of being able to do these operations on sname:VkFence
objects doesn't justify the extra API complexity.
