* Bump API patch number and header version number to 26 for this update.
Github Issues:
* Bring sample code in the +VK_KHR_surface+ and +VK_KHR_swapchain+
extension summary appendices up to date, and note they will be replaced
with pointers to the LunarG SDK examples in the future (public issue
279).
* Add a new <<fundamentals-commandsyntax-results-lifetime,Lifetime of
Retrieved Results>> section specifying that ftext:vkGet* and
ftext:VkEnumerate* results are invariant unless otherwise specified, and
specify behavior for individual commands which are not invariant (public
issue 280).
* Remove conflicting definition of
slink:VkDisplayPlaneCapabilitiesKHR::pname:maxSrcPosition and clean up
language of the remaining definition (public issue 351).
* Fix many minor spelling errors and add rules to the style guide to
prevent recurrences (public issue 352).
Internal Issues:
* Remove redundant descriptions of the etext:VK_USE_PLATFORM_* macros from
the <<wsi,Window System Integration>> chapter in favor of the
description in the <<boilerplate-wsi-header,Window System-Specific
Header Control>> appendix (internal issue 6).
* Replace misleading 'can: be destroyed when not X' with more correct
'must: not be destroyed while X' in the
<<fundamentals-objectmodel-lifetime,Object Lifetime>> section. Disallow
destroying a pipeline layout while a command buffer using it is
recording (internal issue 241).
* Clarify that ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT is valid for
all images used as attachments in elink:VkImageUsageFlagBits and the
slink:VkImageLayout validity language (internal issue 320).
* Note that <<extended-functionality-layers,Layers>> may wrap object
handles, but that this is a generally discouraged. A link to additional
information in the documentation for layer authors is provided (issue
398)
* Replace the mustnot: and shouldnot: macros with equivalent must: not and
should: not to get rid of non-English words while still highlighting
normative language (internal issue 407).
* Disallow creating multisampled images with
ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT in the slink:VkImageLayout
validity language and the <<features-supported-sample-counts,Supported
Sample Counts>> section (internal issue 445).
* Fix typo so that flink:vkCmdDrawIndexedIndirect is defined in terms of
flink:vkCmdDrawIndexed rather than flink:vkCmdDrawIndirect (internal
issue 446).
* Reorganize the per-extension information sections to all be in the
<<extensions,Layers & Extensions>> appendix. Also fix a typo in
+VK_IMG_filter_cubic+ which incorrectly identified it as a +KHR+
extension (internal issue 461).
Other Issues:
* Use asciidoc markup instead of latexmath to simplify diagrams in the
<<features-formats-non-packed,byte mapping tables>> for color formats.
* Fix a markup problem with the wildcarded enumerant names in a NOTE in
the <<textures-texel-replacement,Texel Replacement>> section.
* Fix missing attributes in the XML interface for
elink:VkExternalMemoryHandleTypeFlagBitsNV and
elink:VkExternalMemoryFeatureFlagBitsNV (KhronosGroup/Vulkan-Hpp issue
#25)
* Cleanup reference page builds so only core pages are built for releases.
* Bump API patch number and header version number to 25 for this update.
* Structurally change the specification so that multiple extensions are
included in the +1.0+ git branch, and specifications will include or not
include those extensions at build time based on options passed to the
Makefile. See +doc/specs/vulkan/README.html+ and the ``Layers and
Extensions'' section of the ``Vulkan Documentation and Extensions''
document for more information on this change.
* Register and publish new extensions in the single-branch form:
** +VK_NV_external_memory_capabilities+
** +VK_NV_external_memory+
** +VK_NV_external_memory_win32+
** +VK_NV_win32_keyed_mutex+
Github Issues:
* Clarify description of GetInstanceProcAddr and GetDeviceProcAddr (public
issue 212).
* Add SPIR-V <<textures-operation-validation, instruction validation>> for
single-sampled images (public issue 316).
* Fix spelling of ``tesselation'' in a few places and note it as an
exception to the American spelling rules convention (public issue
327).
* Fix Makefile to create output directory for ``styleguide''
target (public issue 329).
* Fix numerous minor issues with incorrectly tags on enumerant names and
table titles (public issue 330).
* Generate specversion.txt date in UTC time and RFC 2822 format
(public issue 335).
* Convert link to the SPIR-V Specification for
flink:VkShaderModuleCreateInfo into an internal link to the normative
reference (public issue 336).
* Add ename:VK_ERROR_OUT_OF_MEMORY error code to
flink:vkCreateDebugReportCallbackEXT (public issue 337).
Internal Issues:
* Update style guide regarding use of code:NULL and dname:VK_NULL_HANDLE
(internal issue 393).
* Change the definition of latexmath:[$q$] in the
<<textures-image-level-selection,texture image level selection>> section
to be the index of the maximum defined level for the view, not the
number of levels in the view (internal issue 406).
* Allow developers to override dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE
with their own binary-compatible definition (internal issue 439).
* Fix +vk_platform.h+ conditional logic causing compile failure with some
Android compilers (internal issue 441).
* Implement the single-branch model as described above (internal issue
461).
