Vulkan API specifications 1.0.68 released
« Reply #40 on: January 16, 2018, 10:35:48 AM »
Change log for January 15, 2018 Vulkan 1.0.68 spec update:

  * Bump API patch number and header version number to 68 for this update.

Github Issues:

  * Added more details in the
    <<extended-functionality-extensions-compatibility, Extension
    Compatibility>> section, allowing explicit incompatibilities, and
    simplify corresponding language in the style guide, which now defers to
    the API Specification on this point (public issue 638).
  * Fix typo in description of slink:VkCommandBufferLevel::pname:level
    (public issue 651).
  * Only include extension-dependent valid usage statement for
    slink:VkImageSubresourceRange, and note that the extension names for
    header files described in the <<boilerplate-wsi-header, Window
    System-Specific Header Control>> section are only valid links, when the
    specification being viewed is built with the corresponding extensions
    enabled (public issue 652).

Internal Issues:

  * Add language to elink:VkResult specifying that when commands return an
    error, output parameter contents are undefined instead of unmodified
    (except for pname:sType and pname:pNext). Note that this is a behavior
    change. Add notes calling out slink:VkImageFormatProperties as an
    exception (internal issue 1118).
  * Add "`general-purpose`" to the style guide, and correct existing uses of
    "`general purpose`" as an adjective (internal issue 1121).
    for the `VK_EXT_validation_cache` extension, following the same naming
    pattern as other tokens in the extension, but keep the old
    backwards compatibility (internal issue 1126).

Other Issues:

  * Specify that flink:vkCmdSetDiscardRectangleEXT does not affect copies or
    clears, matching existing language for the scissor rectangle test.
  * Move the <<boilerplate-sType, pname:sType>> definition from the
    boilerplate appendix to the Fundamentals chapter, putting it together
    with the valid usage of pname:sType rather than having the definition
    split across two places.
  * Inline all of the etext:Vk*Flags definitions, moving each one from the
    boilerplate appendix to appear either after the corresponding
    etext:Vk*FlagBits value if one is defined, or after the first structure
    that includes them if not.
