* Bump API patch number and header version number to 67 for this update.
* Update copyright dates to 2018
Github Issues:
* Fix texture lookup functions in `GL_KHR_vulkan_glsl` specification
(public pull request 363).
* Clarify the state waited semaphores are left in when a call to
flink:vkQueuePresentKHR fails (public issue 572).
* Cleanup descriptions of slink:VkObjectTablePushConstantEntryNVX and
slink:VkObjectTableDescriptorSetEntryNVX (public issue 583)
* Remove redundant flink:vkCmdSetDiscardRectangleEXT valid usage
statements (public pull 586).
* Make dynamic state array length valid usage statements implicit for
flink:vkCmdSetViewportWScalingNV, flink:vkCmdSetDiscardRectangleEXT, and
flink:vkCmdSetViewport (public pull 589).
* Clarify meaning of window extent (0,0) in slink:VkSwapchainKHR for the
Windows and X11 platforms, in their respective extensions (public issue
590).
* Allow flink:vkGetPastPresentationTimingGOOGLE to return
ename:VK_INCOMPLETE (public issue 604).
* Add synchronization valid usage statements to flink:vkAcquireNextImage
(public pull 611).
* Fix some broken external links and internal xrefs (public pull 613).
* Clean up slink:VkViewport valid usage statements in the presence or
absence of relevant extensions (public pull 623).
* Remove
ename:VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_STENCIL_ATTACHMENT_OPTIMAL_KHR
token from VK_KHR_maintenance2 from the non-extension VU path for
slink:VkGraphicsPipelineCreateInfo (public issue 628).
* Miscellaneous minor markup fixes - extension name strings (public pull
631), Notes (pull 633), queue names emitted by generator scripts (pull
634), block formatting in slink:VkDescriptorUpdateTemplateEntryKHR (pull
635), ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_CUBIC_BIT_IMG (pull
641), quotes and apostrophes (pull 643),
* Miscellaneous minor grammar fixes (public pull 644).
* Fix markup macros so usage like ptext:*Src* works (public pull 647).
Internal Issues:
* Clarify in the `VK_KHR_surface` and `VK_KHR_swapchain` extensions that
parameter combinations which aren't supported for normal images are also
unsupported for presentable images, even if the parameter values are
individually supported as reported by the surface capability queries
(internal issue 1029).
* Fixed XML typo in the valid value field of the pname:sType member of
slink:VkPhysicalDeviceExternalMemoryHostPropertiesEXT (internal issue
1100).
Other Issues:
* Add memory semantics validity rules to the <<spirvenv-module-validation,
Validation Rules within a Module>> section of the SPIR-V environment
appendix, and specify that sequentiality consistency is not supported.
This forbids certain cases like "`Load+Release`" that we don't expect to
ever be meaningful.
* Document mapping of OpenGL Shading Language barriers to SPIR-V scope and
semantics in the `GL_KHR_vulkan_glsl` specification.
New Extensions:
* `VK_EXT_conservative_rasterization`
- add missing `*name` and `*link` and `code`
- change where wrong macro was used
- swap `*name` and `*link` where appropriate
- correct misspelled names
- that sort of thing...
* Bump API patch number and header version number to 65 for this update.
Github Issues:
* Replaced inaccurate "`pixel`" with "`texel`" or "`compressed texel
block`" as appropriate in the <<sparsememory, Sparse Resources>> chapter
(public issue 86).
* Attempt to clarify security/integrity guarantees in the
<<fundamentals-errors, Errors>> section (public issue 147).
* Update the <<memory-device,Device Memory>> section with clarifications
and markup fixes (public pull request 194).
* Fix typo VkDeviceCreateInfo -> slink:VkDebugMarkerObjectNameInfoEXT in
sample code for `VK_EXT_debug_marker` extension (public pull request
227).
* Clarified slink:VkFramebufferCreateInfo language regarding concurrent
use of attachment resources during a render pass instance (public issue
299).
* Added overlap rules for destination regions in <<copies,copy commands>>.
Also unified the sparse and non-sparse source-destination overlap rules,
since the non-sparse rules were technically inaccurate in the face of
aliasing in flink:vkBindMemory2 - the new rules are true regardless
(public issue 317).
* Clarified the <<features-features-samplerAnisotropy,
pname:samplerAnisotropy feature>> to only affect the
slink:VkSamplerCreateInfo::pname:anisotropyEnable value, and that
pname:maxAnisotropy is ignored when pname:anisotropyEnable is VK_FALSE
(public issue 503).
* Clarify pointer valid usage statements to use "`valid pointer to valid
_object_`" terminology and update the
<<fundamentals-validusage-pointers,Valid Usage for Pointers>> section
accordingly (public pull request 547).
* Some operations that use integer coordinates can also accept a LOD to
sample from. Add a description of that selection and the validity
conditions in the new <<textures-integer-coordinate-operations, Integer
Texel Coordinate Operations>> section (public issue 548).
* Update stext:VkImageSubresource* valid usage statements (public pull
request 550).
* Added text tying ename:VK_OUT_OF_POOL_MEMORY error for
flink:vkAllocateDescriptorSets to the number of descriptor types in the
allocating pool. Removed redundant "`length`" text about number of
descriptors returned (public issue 582).
* Update slink:VkSwapchainCreateInfoKHR descriptions (public pull request
585).
* Update slink:VkPipelineViewportWScalingStateCreateInfoNV and related
structures' valid usage statements (public pull request 587).
* Change some dates to conform to ISO 8601 as specified in the style guide
(public pull request 601).
* Fix some math markup problems and be more consistent in use of asciidoc
math markup (public pull request 602).
Internal Issues:
* Clarified that attribute reads from incomplete vertex buffer elements
are considered out of bounds accesses, in the
slink:VkPhysicalDeviceFeatures and flink:vkCmdBindVertexBuffers.txt
sections (internal issue 842).
Other Issues:
New Extensions:
* Bump API patch number and header version number to 61 for this update.
Github Issues:
* Provide alternate length attributes (altlen=) in the XML schema, for
those using length attributes to generate code instead of documentation
(public issue 555).
* Fix erroneous references to `latex:` being used for asciidoc math
markup, rather than `latexmath:` (public pull request 556).
* Add author ID to XML for Kazan software renderer (public pull request
557).
Internal Issues:
* Add the <<fundamentals-abi,Application Binary Interface>> section
describing platform ABI requirements and recommendations, add examples
of function and function pointer declarations to the
<<boilerplate-platform-specific-calling-conventions, Platform-Specific
Calling Conventions>> section, and remove related language that existed
elsewhere in the specification (internal issue 64).
* Describe where to document valid usage interactions of chained
structures in the style guide, and fix one case now appearing in
slink:VkBufferCreateInfo instead of the child
slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue
715).
* Add example to the style guide of describing enumerated types which are
empty when the spec is built without relevant extensions enabled, and
apply it to existing examples for
elink:VkDescriptorSetLayoutCreateFlagBits and
elink:VkSubpassDescriptionFlagBits (internal issue 864).
* Add a note to the <<fundamentals-validusage-enums, Valid Usage for
Enumerated Types>> section that the special values suffixed with
etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and
etext:_MAX_ENUM are not part of the API and should: not be used by
applications (internal issue 872).
* Added note to flink:vkCmdUpdateBuffers explaining the performance
penalty for copies done in this way, and why the upper copy limit is
what it is (internal issue 952).
* Update `VK_KHX_device_group` to split some functionality into the new
`VK_KHR_bind_memory2` extension, and rename that functionality (internal
issue 969).
* Remove *Status* fields from extension appendices, since they are by
definition published and complete by the time they reach the public
github repository (internal issue 973).
Other Issues:
* Update Data Format specification dependency to version 1.2 and change
references to DF sections accordingly.
* Update XML to make the pname:pAllocator parameter of
flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in
the `VK_EXT_display_control` extension as optional.
New Extensions:
* `VK_KHR_bind_memory2`
* `VK_KHR_image_format_list`
* `VK_KHR_maintenance2`
* `VK_KHR_sampler_ycbcr_conversion`
* Bump API patch number and header version number to 60 for this update.
Github Issues:
* Document that <<queries-timestamps, Timestamp Queries>> can only be
meaningfully compared when they are written from the same queue (public
issue 216).
* Document that the `<extension>` tag `type` attribute is required for
non-disabled extensions (derived from, but does not close public issue
354).
* Clean up registry schema length attribute descriptions to be consistent
and correct (public issue 555).
Internal Issues:
* Replace as much of the hand-written extension appendix metadata as
possible with asciidoc includes generated from corresponding attributes
of +vk.xml+, and enhance the style guide to match. This avoids
inconsistencies between +vk.xml+ and the appendices, and produces a more
uniform style (internal issue 137).
* Remove the generated extDependency.{py,sh} files from the tree and
create them dynamically on demand instead, reducing merge conflicts
(internal issue 713).
* Add a prototype tool for generating in-place difference markup for
sections guarded by asciidoc conditionals, and new syntax for open
blocks to support it (internal issue 833).
* Remove unnecessary restriction of etext:*SYNC_FD_BIT_KHR external handle
types to the same physical device in the
slink:VkPhysicalDeviceIDPropertiesKHR,
flink:VkImportMemoryWin32HandleInfoKHR,
slink:VkImportFenceWin32HandleInfoKHR, slink:VkImportFenceFdInfoKHR,
slink:VkImportSemaphoreWin32HandleInfoKHR,
slink:VkImportSemaphoreFdInfoKHR
<<external-memory-handle-types-compatibility, External memory handle
types compatibility>>, <<external-semaphore-handle-types-compatibility,
External semaphore handle types compatibility>>, and
<<external-fence-handle-types-compatibility, External fence handle types
compatibility>> sections (internal issue 956).
Other Issues:
* Remove dependency of +VK_KHX_device_group+ on +VK_KHR_swapchain+ (there
is an interaction, but not a strict dependency), and add a new
`extension` attribute to the `<require` XML tag to allow classifying a
subset of interfaces of an extension as requiring another extension.
Update the registry schema and documentation accordingly.
New Extensions:
* `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask`
GLSL extension)
* `VK_EXT_sample_locations`
* `VK_EXT_validation_cache`
* Bump API patch number and header version number to 56 for this update.
Github Issues:
* Add valid usage statements for commands introduced by
`VK_EXT_debug_report` and `VK_EXT_debug_marker` extensions, regarding
the valid pname:object and pname:objectType values (public issue 495).
* Modify `GL_KHR_vulkan_glsl` specification to document that uniform and
buffer block arrays each take only a single binding (public issue 514).
* Add `KHX` author tag to +vk.xml+ (public issue 526).
Internal Issues:
* Document use of code: macro for non-Vulkan APIs in the style guide
(internal issue 863).
* Document that reference page open block delimiters must not contain
asciidoc section markup in the style guide (internal issue 898).
* Fix <<spirvenv,SPIR-V appendix>> to say
code:VariablePointersStorageBuffer instead of
code:VariablePointersUniformBufferBlock (internal issue 928).
Other Commits:
* Add missing extension structures to dependency attributes in +vk.xml+.
New Extenions:
* `VK_EXT_depth_range_unrestricted`
* Bump API patch number and header version number to 54 for this update.
Github Issues:
Internal Issues:
* Fix tessellation domain to have an upper-left origin in the
<<img-tessellation-topology-ul, tessellation toplogy image>> and related
language. CTS and all implementations were already doing this, it was
just a documentation bug that it was flipped to lower-left (internal
issue 603).
* Add a section to the style guide describing how VUID tags are changed
and removed when the corresponding Valid Usage statements are modified
(internal issue 829).
* Add explicit Valid Usage statement to
slink:VkPipelineDynamicStateCreateInfo to require that members of
pname:pDynamicStates must be unique (internal issue 851).
New Extensions:
* `VK_KHR_16bit_storage`
* `VK_KHR_dedicated_allocation`
* `VK_KHR_external_fence`

* `VK_KHR_win32_keyed_mutex`
* Bump API patch number and header version number to 42 for this update
(the first anniversary edition).
Github Issues:
* Changed asciidoctor macros so cross-page links in the standalone
reference pages function properly (public issue 462).
Internal Issues:
* Clarified host visibility discussion for slink:VkMemoryType,
flink:vkInvalidateMappedMemoryRanges, elink:VkAccessFlagBits, and the
<<synchronization-framebuffer-regions,Framebuffer Region Dependencies>>
section, removing duplicated information and adding a central definition
in the access types section (internal issue 552).
* Change description of
slink:vkGetPhysicalDeviceSurfacePresentModesKHR::pname:pPresentModes to
return an array of values, not structures (internal issue 699).
New Extensions:
