82e0f83d43 Change log for February 10, 2017 Vulkan 1.0.40 spec update:
* Bump API patch number and header version number to 40 for this update.
  * There is a major build change in this release. We are now using the
    Ruby-based ``asciidoctor'' implementation, rather than the Python-based
    ``asciidoc'' implementation, to process the specification. While the
    actual specification markup changes were minimal, this requires a new
    set of build tools and a very different installation process, especially
    because we now use an experimental direct-to-PDF backend for Asciidoctor
    instead of Docbook->dblatex->PDF. It is no longer possible to build the
    Specification using asciidoc. See doc/specs/vulkan/README.adoc
    for some guidance on installing the new toolchain components.
  * There are some minor rendering issues in the PDF output due to teething
    problems with the asciidoctor toolchain, especially with mathematical
    equations. We are aware of these and working on them.

Github Issues:

  * Updated sample code for the <<sparsememory-examples-basic,sparse
    resource binding example>> (public issue 97).
  * Modify line and point clipping behavior in the
    <<vertexpostproc-clipping, Primitive Clipping>> section to allow for
    pop-free behavior. The ability to check for which behavior is
    implemented may be added a future feature or extension (public issue
    113).
  * Unify the discussions of implicit ordering throughout the spec, in
    particular in the new sections <<drawing-primitive-order, Primitive
    Order>>, <<primrast-order, Rasterization Order>>, and
    <<synchronization-implicit, Implicit Synchronization Guarantees>>; the
    discussion of <<synchronization-submission-order, submission order>>;
    and references elsewhere to these sections (public issue 133).
  * Clarify \<\<descriptorsets-compatibility,Pipeline Layout Compatibility>>
    language and introduce the term ``identically defined'' (public issue
    164).
  * Add a dependency to the +VK_EXT_debug_marker+ extension that's needed to
    reuse the object type enum from +VK_EXT_debug_report+, and moves the
    definition of that enum into +VK_EXT_debug_report+ where it should be
    (public issue 409).
  * Remove redundant valid usage statement from slink:VkImageBlit (public
    issue 421).
  * Update GL_KHR_vulkan_glsl to allow the ternary operator to result in a
    specialization constant (public issue 424).
  * Fix valid usage for flink:VkPipelineShaderStageCreateInfo (public issue
    426).
  * Correct typo in New Objects list for <<VK_EXT_debug_report>> (public
    issue 447).

Internal Issues:

  * Moved to asciidoctor for spec builds (internal issue 121).
  * Update style guide to describe where to put new extensions-specific
    asciidoc files, and what to name them (internal issue 626).
  * Add src/spec/indexExt.py to autogenerate registry index entries linking
    into the 1.0-extensions specification, instead of maintaining the index
    manually. (internal issue 642).
  * Autogenerate extension dependencies and lists of all extensions and all
    KHR extensions from the "supported" attributes in +vk.xml+. Execute
    +make config/extDependency.sh+ from +doc/specs/vulkan+ when a supported
    extension is added to vk.xml, to regenerate the dependency script. The
    consequence is that specifying a single extension to the +makeExt+
    script will automatically enable all extensions it depends on as well,
    and that the +makeAllExts+ and +makeKHR+ scripts do not need to be
    updated when a new extension is supported (internal issue 648).
  * Put extension appendices all at the same asciidoc section level, so KHR
    WSI extensions show up in the HTML index (internal issue 648).

Other Issues:

  * Imbed images in the generated HTML specs instead of loading them from
    the images/ directory.
  * Fix missing EXT in extension name
    (ename:VK_EXT_SWAPCHAIN_COLOR_SPACE_EXTENSION_NAME).
  * Add new +VK_EXT_SMPTE_2086_metadata+ extension.
  * In the <<platformCreateSurface_xlib,Xlib Surface>> section of the
    +VK_KHR_xlib_surface+ specification, add language warning users that
    they always need to call code:XinitThreads.
  * Use the term "presentable image" (rather than "swapchain image")
    consistently in +VK_KHR_swapchain+ and related extensions, and add a
    glossary term defining it.
  * Relocate the valid usage for samples of
    flink:vkGetPhysicalDeviceSparseImageFormatProperties2KHR::pname:pFormatInfo
    to be below the flink:VkPhysicalDeviceSparseImageFormatInfo2KHR
    structure.

348990517c Change log for September 30, 2016 Vulkan 1.0.29 spec update:
* Bump API patch number and header version number to 29 for this update.

Github Issues:

  * Remove redundant constraint on
    slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue
    224).
  * Fix typo and remove link in Note in the
    <<extended-functionality-instance-extensions-and-devices, Instance
    Extensions and Device Extensions>> section (public issue 359).
  * Fix erroneous validation statement for the pname:layout member of
    slink:VkComputePipelineCreateInfo (public issue 362).

Internal Issues:

  * Restore long figure captions using asciidoc sidebar blocks, due to
    restrictions of asciidoc syntax (internal issue 101).
  * Replace most latexmath equations with comparable markup in straight
    asciidoc, which significantly improves time required to fully load and
    process the HTML forms of the Specification. There are known minor font
    and alignment inconsistencies with MathJax and PDF rendering of
    latexmath equations. Please do not file github issues about these. We
    are aware of the inconsistencies and will make refinements over time,
    while the performance improvements are compelling in at least some major
    browsers (internal issue 313).
  * Move handcoded validity statements from +vk.xml+ into the Specification
    body, easing work in the single-branch model. Specify the distinction
    between these explicit statements, and the implicit validity statements
    inferred from vk.xml. Validity statements now appear in two blocks for
    each command and structure - handcoded "Valid Usage" and the implicit
    "Valid Usage (Implicit)" (internal issue 392).
  * Add the +returnedonly="false"+ attribute to WSI output structures,
    removing incorrectly generated implicit validity statements for
    slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR,
    slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR,
    slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures
    (internal issue 486).
  * Update slink:VkImageLayout to require the
    ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images
    (internal issue 487).
  * Use an explicit format specifier string for the date command invocation
    in the +Makefile+ instead of the shorthand -R option, which doesn't work
    on BSD and MaxOS X date commands (internal issue 500).

Other Issues:

  * Use the terms ``allocation scope'' and ``extension scope'' instead of
    just ``scope'', and add them to the glossary.
