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 July 21, 2017 Vulkan 1.0.56 spec update: * Bump API patch number and header version number to 56 for this update. Github Issues: * Add valid usage statements for commands introduced by `VK_EXT_debug_report` and `VK_EXT_debug_marker` extensions, regarding the valid pname:object and pname:objectType values (public issue 495). * Modify `GL_KHR_vulkan_glsl` specification to document that uniform and buffer block arrays each take only a single binding (public issue 514). * Add `KHX` author tag to +vk.xml+ (public issue 526). Internal Issues: * Document use of code: macro for non-Vulkan APIs in the style guide (internal issue 863). * Document that reference page open block delimiters must not contain asciidoc section markup in the style guide (internal issue 898). * Fix <<spirvenv,SPIR-V appendix>> to say code:VariablePointersStorageBuffer instead of code:VariablePointersUniformBufferBlock (internal issue 928). Other Commits: * Add missing extension structures to dependency attributes in +vk.xml+. New Extenions: * `VK_EXT_depth_range_unrestricted`

This extension removes the slink:VkViewport pname:minDepth and
pname:maxDepth restrictions that the values must be between `0.0` and `1.0`,
inclusive.
It also removes the same restriction on
slink:VkPipelineDepthStencilStateCreateInfo pname:minDepthBounds and
pname:maxDepthBounds.
Finally it removes the restriction on the pname:depth value in
slink:VkClearDepthStencilValue.

=== Issues
1) How do slink:VkViewport pname:minDepth and pname:maxDepth values outside
of the `0.0` to `1.0` range interact with
<<vertexpostproc-clipping,Primitive Clipping>>?
**RESOLVED**: The behavior described in <<vertexpostproc-clipping,Primitive
Clipping>> still applies.
If depth clamping is disabled the depth values are still clipped to [eq]#0
{leq} z~c~ {leq} w~c~# before the viewport transform.
If depth clamping is enabled the above equation is ignored and the depth
values are instead clamped to the slink:VkViewport pname:minDepth and
pname:maxDepth values, which in the case of this extension can be outside of
the `0.0` to `1.0` range.
2) What happens if a resulting depth fragment is outside of the `0.0` to
`1.0` range and the depth buffer is fixed-point rather than floating-point?
**RESOLVED**: The supported range of a fixed-point depth buffer is `0.0` to
`1.0` and depth fragments are clamped to this range.
