7f7686d7f2 Change log for August 5, 2016 Vulkan 1.0.23 spec update: 
* Bump API patch number and header version number to 23 for this update.

Github Issues:

  * Add explicit valid value attributes to pname:sType members in vk.xml
    (public issue 34).
  * Clarify usage of flink:vkGetInstanceProcAddr and
    flink:vkGetDeviceProcAddr (public issue 225).
  * Fix a copy-and-paste error in the description of
    pname:pSwapchainImageCount saying that it was the count of ``format
    pairs'' instead of ``swapchain images'' (public issue 292).
  * flink:vkCmdExecuteCommandBuffers requires all command buffers to be
    allocated from command pools created for the same queue family (public
    issue 296).
  * Remove bogus +optional+ attribute for
    flink:vkEnumerateDeviceLayerProperties::pname:physicalDevice from vk.xml
    (public issue 301).
  * Clean up the <<resources-image-views-compatibility,image and image view
    compatibility table>> reference and contents. Use full enumerant names.
    Refer to pname:layerCount in the ``view parameters'' column instead of
    pname:arrayLayers. Require N >= 1 for the cube array subview row, not
    just arrayLayers >= 6 N (public issue 304).
  * Modify description of <<resources-memory-aliasing,memory aliasing>> to
    be consistent with the description of
    <<resources-bufferimagegranularity,buffer image granularity>> (public
    issue 307).

Internal Issues:

  * Describe remaining +vk_platform.h+ macros in the <<boilerplate,API
    Boilerplate>> appendix (internal issue 6).
  * Clarify
    <<features-features-robustBufferAccess,pname:robustBufferAccess>>
    feature behavior; what memory can be accessed, how bounds checking is
    performed, and allowing for vectorization (internal issue 332).
  * Document markup for automatic extraction of reference pages from the
    spec sources in the style guide (internal issue 395).
  * Allow flink:vkCreateDisplayModeKHR to return
    ename:VK_ERROR_INITIALIZAION_FAILED_KHR if the user requests mode
    parameters that the specified display does not support (internal issue
    411).
  * Remove atomic counters (atomic_uint style) from KHR_vulkan_glsl, and
    more clearly remove the subroutine keyword alongside it (internal issue
    421).
  * Clarify behavior of flink:vkCmdBindDescriptorSets for descriptor sets
    not contained in the layout (internal issue 427).

Other Commits:

  * Change the order in which members of sname:VkAttachmentDescription and
    sname:VkPipelineInputAssemblyStateCreateInfo are described to match
    their order in the structures.

f4c4113d07 Change log for July 15, 2016 Vulkan 1.0.21 spec update: 
* Bump API patch number and header version number to 21 for this update.

Github Issues:

  * Clarify how <<features-supported-sample-counts,sample count queries>>
    relate to the limits in slink:VkPhysicalDeviceLimits. (public issue
    185).
  * Clarify in the <<interfaces-iointerfaces,Shader Input and Output
    Interfaces>> section that shader output variables have undefined values
    until the shader writes to them (public issue 240).
  * Specify the implicit value of image parameters that cannot be set in
    slink:VkSwapchainCreateInfo::pname:flags, pname:imageType,
    pname:mipLevels, pname:samples, pname:tiling, and pname:initialLayout
    (public issue 243).
  * Make use of code:NULL and code:VK_NULL_HANDLE consistent in the
    VK_KHR_swapchain extension (public issue 276).

Internal Issues:

  * Clarify that presenting an image to a display surface swapchain applies
    the display surface's mode, and that destroying a display surface
    swapchain may reset the display's mode, in the VK_KHR_display_swapchain
    extension (internal issue 247).
  * Better describe what a slink:VkSurfaceKHR is, and that creating one does
    not set a mode, in the VK_KHR_display extension. This is a round-about
    way of pointing out that mode setting is not covered by the extension,
    but rather is performed as a side effect of presentation (internal issue
    247).
  * Add more valid usage statements to flink:vkQueuePresentKHR command when
    the VK_KHR_display_swapchain extension is present (internal issue
    247).
  * Add more includes to the VK_KHR_swapchain extension to better document
    interactions with VK_KHR_display_swapchain (internal issue 247).
  * Clarify restrictions on location aliasing in the
    <<fxvertex,Fixed-Function Vertex Processing>> section (internal issue
    370).
  * Add mathematical description of blitting to flink:vkCmdBlitImage, and
    link it to the <<textures,Image Operations>> chapter. Use mathematical
    notation for ranges of texel coordinates in the <<textures,Image
    Operations>> chapter. Fixed miscellaneous validity statements for
    flink:vkCmdBlit and slink:VkImageBlit (internal issue 382).

Other Commits:

  * Added a valid usage rule to flink:VkGraphicsPipelineCreateInfo that the
    ename:VK_PRIMITIVE_TOPOLOGY_PATCH_LIST topology must only be used when
    tessellation shaders are used.
  * Expand the style guide into a formal "Procedures and Conventions"
    document. Add a API Naming Conventions section, move most of the API
    Specification Appendix C (Layers and Extensions) content into the new
    document, and define the resulting procedures as mandatory (where
    relevant). This more clearly separates use vs. specification of Vulkan
    APIs.
  * Update vk_platform.h to handle 32-bit ARMv8 binaries.
  * Various minor cleanups to the Makefile and build process.

5de77cf663 Change log for June 10, 2016 Vulkan 1.0.16 spec update: 
* Bump API patch number and header version number to 16 for this
    update.

Github Issues:

  * Clarify that integer border values are meant to be 0/1, and that
    integer texture lookups are sign-extended in the
    <<textures-format-conversion,Format Conversion>> and
    <<textures-texel-replacement,Texel Replacement>> sections (public
    issue 52).
  * Add logic to generate spec boilerplate without using the 'git'
    command-line client, needed when building from a tarball or another
    source of the Vulkan tree rather than a cloned git repo. Remove
    boilerplate as part of 'clean' target (public issue 195).
  * Document that color writes and clears to unused attachments have no
    effect for slink:VkClearAttachment and
    elink:VkColorComponentFlagBits (public issue 198).
  * Fixed flink:vkCmdExecuteCommands validity statement for
    sname:VkCommandBufferInheritanceInfo::pname:framebuffer. If used, it
    must match the framebuffer in the current renderpass instance
    (public issue 226).
  * Added valid usage language to require for all functions that set
    dynamic state that the currently bound graphics pipeline has the
    corresponding dynamic state enabled (public issue 235).

Internal Issues:

  * Clarify for flink:vkEnumerateInstanceExtensionProperties, in the
    <<extended-functionality-instance-extensions-and-devices, Instance
    Extensions and Device Extensions>> section, and in the
    <<glossary,Glossary>> section when functionality should be exposed
    as an instance extension, as a device extension, or as both
    (internal issue 109).
  * Place WorkgroupSize in alphabetical order in the
    <<interfaces-builtin-variables,Built-in Variables>> section
    (internal issue 323).
  * Corrects valid usage in vkEndRenderPass to only affect primary
    render passes, as secondaries may be entirely within a render pass,
    and should be able to be ended (previous language disallowed that)
    (internal issue 338).
  * Fix relational operator from <= to >= in the
    <<features-extentperimagetype,Allowed Extent Values>> section
    (internal issue 343).
  * Disallow recursion under SPIR-V entry points in the
    <<spirvenv-module-validation,Validation Rules within a Module>>
    section (internal SPIR-V issue 37).

Other Commits:

  * Use standard Python ElementTree package instead of lxml.etree in
    header / validation layer / include autogeneration from XML,
    reducing platform dependencies.

* Bump API patch number and header version number to 12 for this
    update.

Github Issues:

  * Change valid usage statements intended to be "sub-points" to
    be actual sub-points (public issue 66).
  * Replace double negation in description of
    slink:VkRenderPassBeginInfo::pname:pClearValues (based on public
    merge 142).
  * Cleanup minor typos in spec, ref pages and XML, including those
    proposed in public pull requests 144, 150, 151, 167, 168, 181, and
    186.
  * Use *strict subset* in describing the partial order of memory
    property types for slink:VkMemoryType, and update the style guide
    accordingly (public issue 190).
  * Fix various "a image" -> "an image" typos (public issue 191).
  * Note in the <<fundamentals-validusage,Valid Usage>> and
    <<extensions-interactions,Extension Interactions>> sections that
    structures defined by extensions which may be passed in structure
    chains using the ptext:pNext member must: include initial
    ptext:sType and ptext:pNext members (public issue 192).

Internal Issues:

  * Remove duplicate language from the description of the pname:fence
    parameter to flink:vkQueueSubmit and improve validity language
    (internal issue 91).
  * Added documentation for "optional" attribute to XML readme.tex/pdf
    (internal issue 149).
  * Clarify the host-side data validity rules and behavior of
    flink:vkFlushMappedMemoryRanges and
    flink:vkInvalidateMappedMemoryRanges (internal issue 266).

Other Commits:

  * Added clarification to flink:vkCmdFillBuffer regarding the use of
    ename:VK_WHOLE_SIZE.
  * Fixed and documented implementation of "validextensionstructs"
    attribute. in XML processing scripts and readme.tex/pdf.
  * Add missing validity statements to flink:vkResetEvent and
    flink:vkCmdResetEvent.
  * Fix validity for the
    ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT flag.
    Correct all the draw/dispatch commands to mention optimally tiled
    images as well as linear tiled images, and say image VIEWS instead
    of images. Add validity statement to flink:vkCmdBlitImage
  * Replace the {apiname} macro with hardcoded "Vulkan", now that we've
    committed to that name.
  * Add the VK_AMD_rasterization_order extension to vk.xml.

6db51e9241 Change log for April 22, 2016 Vulkan 1.0.11 spec update: 
* Bump API patch number and header version number to 11 for this
    update.

Github Issues:

  * Clarify the WSI extension language by switching from the fuzzier
    "ownership" language to more-consistent "acquire" language (public
    issue 117).
  * Clarify that memory barriers apply to all commands in the dependency
    chains in the flink:vkGetRenderAreaGranularity command and the
    <<synchronization-execution-and-memory-dependencies,Execution And
    Memory Dependencies>> section (public issue 132).
  * Clarify that a queue family is a set of queues in the
    <<fundamentals-execmodel,Execution Model>> section (public issue
    166).
  * Removed requirement from valid usage language that
    VkPresentInfoKHR::waitSemaphoreCount must be greater than 0 (public
    issue 171).
  * Fix broken internal links, describe structures consistently, use
    consistent style for SPIR-V codewords, and tag normative terms that
    were missing asciidoc tags (public issue 183 and ancillary
    markup/normative language fixes).
  * Fix typos for slink:VkPhysicalDeviceLimits member names in
    slink:VkImageCreateInfo validity language (public issue 184).

Internal Issues:

  * Document that the requested patch version number specified as part
    of slink:VkApplicationInfo::pname:apiVersion is ignored when
    creating an instance (internal issue 176).
  * Clarify handling of extension structs in the
    <<fundamentals-validusageValid Usage>> section (internal issue 254).
  * Update required slink:VkImageFormatProperties::pname:maxMipLevels to
    be limited to the maximum allowed mipmap pyramid size corresponding
    to the actual maximum supported size for the format (internal issue
    256).
  * Modify the <<features-extentperimagetype,Allowed Extent Values Based
    On Image Type>> section so the allowed maximum extent is the maximum
    image dimension supported for each dimension of the type of texture
    being queried (internal issue 257).
  * Clarify in the <<spirvenv-module-validation,Validation Rules within
    a Module>> section that at least one of the code:LocalSize execution
    mode or code:WorkgroupSize decoration is required for each compute
    shader entry point in a shader module (internal issue 279).
  * Add validity rules for formats in flink:vkCmdClearColorImage and
    flink:vkCmdClearDepthStencilImage (internal issue 283).
  * Clarify that slink:VkImageFormatProperties::pname:maxResourceSize is
    an upper bound, and that it may not be possible to create an image
    anywhere near that size (internal issue 284).

Other Commits:

  * Fix various minor markup errors reported by validation scripts.
  * Change copyright from Khronos Free Use License to Apache 2.0 license
    on relevant script/XML/header files. This does not affect the
    specification source copyright.

7380aee56b Change log for March 4, 2016 Vulkan 1.0.5 spec update: 
* Bump API patch number to 5 for this update.

Github Issues:
  * Correctly describe slink:VkPhysicalDeviceProperties pname:deviceName
    member as a string, not a pointer to a string. Also one typo fix for
    "hetereogeneous" (public issue 4).
  * Replace maynot: macro with may: not, and "may: or maynot:" with
    "may:" (public issue 4).
  * Clarify that redundantly setting the state of a fence or event has
    no effect (public issue 4).
  * Minor fixes to ref pages to track descriptions of memory bits that
    changed in the core spec. Fix name of a member in the description of
    sname:sname:VkPipelineMultisampleStateCreateInfo (public issues 8,
    13).
  * Remove redundant validity statement for
    sname:VkGraphicsPipelineCreateInfo::pname:stageCount (public issue
    14).
  * Fix typos in chapters 7-9 (public issue 14).
  * Clarify the example demonstrating the behavior of
    code:OpMemoryBarrier in the
    &lt;&lt;shaders-execution-memory-ordering,shader memory acces
    ordering>> section (public issue 16).
  * Specify that freeing mapped memory implicitly unmaps the memory in
    the description of flink:vkFreeMemory (public issue 17).
  * Forbid allocation callbacks from calling into the API in the
    &lt;&lt;memory-allocation,memory allocation>> section (public issue
    20).
  * Add missing validity rules about size being greater than 0 and
    offset being less than size of object. Fix
    flink:VkMappedMemoryRange's misinterpretation of offset (public
    issues 27, 31).
  * Add validity rule disallowing overlapping source/destination
    descriptors in flink:VkCopyDescriptorSet (public issue 32).
  * Clarify that array and matrix stride has to be a multiple of the
    base alignment of the array or matrix in the
    &lt;&lt;interfaces-resources-layout,Offset and Stride Assignment>>
    section (public issue 38).
  * Correct parenthesis floor nesting error in equation for
    &lt;&lt;textures-RGB-sexp,RGB to shared exponent conversion>>.
    Clarify case of when exp' is forced to 0, avoiding log2(0) undefined
    problem (public issue 40).
  * Remove redundant statement from the code:FragDepth description in
    the &lt;&lt;interfaces-builtin-variables,Built-In Variables>>
    section (public issue 47).
  * Define the clamping of the
    &lt;&lt;textures-level-of-detail-operation,bias added to the scale
    factor>> by linking to the slink:VkPhysicalDevice feature
    pname:maxSamplerLodBias (public issue 64).
  * Fix typo "optimal linear resources" and clarify the set of resources
    &lt;&lt;features-limits-bufferImageGranularity,the
    pname:bufferImageGranularity resource>> applies to (public issue
    67).
  * Replace 'descriptor accessed by a pipeline' language for
    sname:VkDescriptorSetAllocateInfo with more precise phrasing about
    binding a descriptor set before a command that invokes work using
    that set (public issue 69).
  * tstripadj.svg contained an Inkscape tag which caused Firefox and IE
    11 to fail to render it, and was illegal SVG. Generating Plain SVG
    from the Inkscape SVG source fixes this (public issue 70).
  * Fix validity for sname:VkVertexInputBindingDescription and
    sname:VkVertexInputAttributeDescription numbers (public issue 72).

Internal Issues:
  * Clarify the meaning of
    ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT in
    elink:VkFormatFeatureFlagBits with respect to depth compare
    (internal issue 107).
  * Added a note explaining that ename:VK_QUEUE_TRANSFER_BIT may or may
    not be reported for a queue family that already supports
    ename:VK_QUEUE_GRAPHICS_BIT or ename:VK_QUEUE_COMPUTE_BIT as the
    former is a strict subset of the latter ones (internal issue 116).
  * Add validity language for sname:VkDescriptorSetAllocateInfo about
