* 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`

|
An application using external memory may wish to synchronize access to that
|
|
memory using fences.
|
|
This extension enables an application to create fences from which non-Vulkan
|
|
handles that reference the underlying synchronization primitive can be
|
|
exported.
|
|
|
|
=== New Object Types
|
|
|
|
None.

=== New Enums
|
|
|
|
* elink:VkFenceImportFlagBitsKHR

|
=== Issues
|
|
|
|
This extension borrows concepts, semantics, and language from
|
|
<<VK_KHR_external_semaphore,VK_KHR_external_semaphore>>.
|
|
That extension's issues apply equally to this extension.
