Change log for August 26, 2016 Vulkan 1.0.25 spec update: * 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). Other Issues:

Change log for September 6, 2016 Vulkan 1.0.26 spec update: * 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.
