Change log for March 5, 2018 Vulkan 1.1.72 spec update: * Update release number to 72. Github Issues: * Restructure the repository to put the specification `Makefile` and associated spec source material at the top level, `vk.xml` and associated scripts material in `xml/`, and generated include and source files in `include/vulkan/` and `src/ext_loader/`, respectively (public issue 436). * Add missing bullet point markup to flink:vkCmdCopyImage valid usage statement, so it gets a VUID assigned (public issue 627). * Fix broken links in a couple of extension appendices (public pull request 665). * Add the \<platform> tag to the index in section 4.1 of the registry schema documentation, and add the protect= attribute of \<extension> tags to the comments in `registry.rnc` (public issues 673, 678). * Add missing valid usage statements for sparse image interactions to flink:VkImageCreateInfo (public pull request 675). * Fix improper usage and grammar of "`can: not`" (public pull request 681). * Remove duplicate spec language and NOTE on present layout between the flink:vkAcquireNextImageKHR and flink:vkAcquireNextImage2KHR commands (public pull request 685). * Fix some typos and markup issues (public pull request 689; public issues 642, 667, 687). * Fix typo etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT -> ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT in the <<external-semaphore-handle-types-compatibility, External semaphore handle types compatibility>> table (public pull request 691). Internal Issues: * Remove the need for the "`noautovalidity`" attribute on extension structures in `vk.xml`. It is now implied by the "`structextends`" attribute instead (internal issue 942). * Replace uses of "`currently bound`" with "`bound`", since "`currently`" is redundant and distracting, and add a corresponding rule to the style guide (internal issue 993). * Fixed subtle issues with the last updates to flink:vkAcquireNextImageKHR language that had resulted in ambiguities (internal issue 1178). * Make it clear that only one query of a given type is allowed at a time by reordering valid usage statements for flink:vkCmdBeginQuery and flink:vkCmdEndQuery, and removing redundant ones (internal issue 1213). * Swapped OL1 and OL3 in `tessparamUL.svg` to match previous version, and fixed where "`(no edge)`" appears (internal issue 1215). Other Issues: * Fixed a minor problem with the valid usage statement extraction script, and corresponding markup in the spec source. New Extensions: * `VK_AMD_shader_core_properties` * `VK_EXT_descriptor_indexing` * `VK_NV_shader_subgroup_partitioned`

This extension exposes shader core properties for a target physical device
through the VK_KHR_get_physical_device_properties2 extension.
Please refer to the example below for proper usage.
=== New Object Types
None.
=== New Enum Constants
* Extending ename:VkStructureType:
** ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_CORE_PROPERTIES_AMD
=== New Enums
None.
=== New Structures
Change log for August 13, 2018 Vulkan 1.1.83 spec update: * Update release number to 83. Public Issues: * Use [%inline] directive for all SVGs to reduce file size (public pull request 734). * Convert XML `value` aliases into \<alias> tags (public pull request 747). * Fix metadoc script showing non-selected extensions (public pull request 748). * Reapply public pull request 742 to make ename:VK_PIPELINE_STAGE_CONDITIONAL_RENDERING_BIT_EXT part of the graphices pipeline (public pull request 749). * Fix numerous typos related to accidental duplication of words (public pull request 760). * Fix `vk.xml` contact typos (public pull request 761). Internal Issues: * Add images to the <<Standard sample locations>> table (internal issue 1115). * Add a definition of "`Inherited from`" precision in the <<spirvenv-precision-operation, Precision and Operation of SPIR-V Instructions>> section (internal issue 1314). * Clarify that both built-in and user-defined variables count against the location limits for shader interfaces in the <<interfaces-iointerfaces-locations, Location Assignment>> section (internal issue 1316). * Merge "`required`" capabilities into the <<spirvenv-capabilities-table, list of optional: SPIR-V capabilities>> (internal issue 1320). * Relax the layout matching rules of descriptors referring to only a single aspect of a depth/stencil image, by reference to the new <<resources-image-layouts-matching-rule, Image Layout Matching Rules>> section (internal issue 1346). * Revert extension metadoc generator warning about name mismatches to a diagnostic, due to annoying warnings in build output for conscious choices we've made (internal issue 1351). Other Issues: * Reserve bits for pending vendor extensions. * Make Vulkan consistent with SPIR-V regarding code:DepthReplacing and code:FragDepth in the <<interfaces-builtin-variables, Built-In Variables>> section. * Add missing ChangeLog entries for the previous three spec updates.
