Jon Leech 64fa8ef4df Change log for November 27, 2017 Vulkan 1.0.66 spec update:
* Bump API patch number and header version number to 66 for this update.

Github Issues:

  * Clarified how and when ename:VK_ERROR_TOO_MANY_OBJECTS is generated in
    flink:vkAllocate Memory, and remove incorrect valid usage statement
    about exceeding the API limit (public issue 356).
  * Minor clarification of the description of
    flink:vkUpdateDescriptorSetWithTemplateKHR::pname:descriptorUpdateTemplate
    (public issue 564).
  * Minor fixes for flink:vkCmdSetViewportWScalingNV (public pull request
    588).
  * Fix random name markup issues (public pull request 603).
  * Fix code:BuiltIn decoration typo in the <<fxvertex-attrib, Vertex
    Attributes>> section (public pull request 606).
  * Fix synchronization language following the definition of
    flink:vkAcquireNextImageKHR (public issue 607).
  * Restore descriptions of several commands and structures missing from the
    generated spec due to a mistyped asciidoctor conditional (public issue
    612).
  * Fix 1.0.41 changelog to refer to public issues 403/404 (public issue
    618).

Internal Issues:

  * Refactor valid usage statements with internal conditionals in
    `copies.txt`, `pipelines.txt`, `renderpass.txt`, and `resources.txt` so
    each branch of the conditional appears as a standalone statement which
    can contain a separate VUID. This should have no impact on the generated
    specs, but is necessary given the present state of the VU extractor and
    the validation layer code that consumes them (internal issue 1043).
  * Fix VkQueueGlobalPriorityEXT enum values missing _EXT suffix (internal
    issue 1045).
  * Clarified initial ownership of resources bound to shared memory objects,
    (internal issue 1068).
  * Fix duplicated valid usage ID tag for flink:vkCmdCopyImage, and make the
    required layouts include ename:VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIONAL in
    both cases (internal issue 1084).

Other Issues:

  * Remove the noise functions from GLSL for SPIR-V for Vulkan in the
    `GL_KHR_vulkan_glsl.txt` extension.

New Extensions:

  * `VK_EXT_external_memory_host`
  * `VK_EXT_external_memory_dma_buf`
  * `VK_EXT_queue_family_foreign`

Vulkan^(R)^ API Documentation Project
=====================================

This repository contains formal documentation of the Vulkan API. This
includes the main API Specification, the reference (man) pages, the XML API
Registry, and related tools and scripts.

Single-Branch Model
-------------------

As of the 1.0.25 release, we have switched to a new "`single-branch`" model
in which all extensions are included in the source of the 1.0 branch of the
Specification, and can be configured in or out of the build using Makefile
options.

Repository Structure

```

Building the Specification and Reference Pages
----------------------------------------------

As of the 1.0.40 release, we have moved from the old `asciidoc` toolchain to
a new one based on `asciidoctor`. See `doc/specs/vulkan/README.adoc` for
more information on installing the toolchain and building the Specification.

Generating Headers and Related Files
------------------------------------

The header file (`src/vulkan/vulkan.h`) and many parts of the specification
and reference page documents are generated from descriptions in the XML API
Registry (`src/spec/vk.xml`). The generated files, with the exception of
`vulkan.h`, are not checked into the repository. If you change `vk.xml`, you
can regenerate the header by going to `src/spec` and running:

    $ make clobber install

The other generated files are built as required via dependencies in
`doc/specs/vulkan/Makefile` .
