Change log for July 13, 2017 Vulkan 1.0.54 spec update: * Bump API patch number and header version number to 54 for this update. Github Issues: Internal Issues: * Fix tessellation domain to have an upper-left origin in the <<img-tessellation-topology-ul, tessellation toplogy image>> and related language. CTS and all implementations were already doing this, it was just a documentation bug that it was flipped to lower-left (internal issue 603). * Add a section to the style guide describing how VUID tags are changed and removed when the corresponding Valid Usage statements are modified (internal issue 829). * Add explicit Valid Usage statement to slink:VkPipelineDynamicStateCreateInfo to require that members of pname:pDynamicStates must be unique (internal issue 851). New Extensions: * `VK_KHR_16bit_storage` * `VK_KHR_dedicated_allocation` * `VK_KHR_external_fence` * `VK_KHR_external_fence_capabilities` * `VK_KHR_external_fence_fd` * `VK_KHR_external_fence_win32` * `VK_KHR_get_memory_requirements2` * `VK_KHR_storage_buffer_storage_class` * `VK_KHR_variable_pointers` Extensions Promoted From KHX To KHR Status: * `VK_KHR_external_memory` * `VK_KHR_external_memory_capabilities` * `VK_KHR_external_memory_fd` * `VK_KHR_external_memory_win32` * `VK_KHR_external_semaphore` * `VK_KHR_external_semaphore_capabilities` * `VK_KHR_external_semaphore_fd` * `VK_KHR_external_semaphore_win32` * `VK_KHR_win32_keyed_mutex`

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`

their level of support for the +SPV_KHR_variable_pointers+ SPIR-V extension.
The SPIR-V extension allows shader modules to use invocation-private
pointers into uniform and/or storage buffers, where the pointer values can
be dynamic and non-uniform.
The +SPV_KHR_variable_pointers+ extension introduces two capabilities.
Fix random name markup - add missing `*name` and `*link` and `code` - change where wrong macro was used - swap `*name` and `*link` where appropriate - correct misspelled names - that sort of thing...

this extension is advertised?
*RESOLVED*: Add it as a distinct feature, but make support mandatory.
Adding it as a feature makes the extension easier to include in a future
core API version.
In the extension, the feature is mandatory, so that presence of the
extension guarantees some functionality.
When included in a core API version, the feature would be optional.
2) Can support for these capabilities vary between shader stages?
*RESOLVED*: No, if the capability is supported in any stage it must be
supported in all stages.
3) Should the capabilities be features or limits?
*RESOLVED*: Features, primarily for consistency with other similar
extensions.
