Change log for July 1, 2016 Vulkan 1.0.19 spec update: * Bump API patch number and header version number to 19 for this update. Github Issues: * Clarified how flink:vkGetImageSubresourceLayout interacts with image layouts (public issue 247). * Remove ename:VK_IMAGE_LAYOUT_PREINITIALIZED from valid usage rule for slink:VkImageMemoryBarrier::pname:oldLayout. It is only valid if it is the current layout (public issue 248). * Modify valid usage for flink:vkBindBufferMemory so implementations are free to require a different backing memory size than the buffer size (public issue 251). * Clarify that filtering rules for flink:vkCmdBlitImage always apply, and are usually no-ops if the formats are the same (public issue 253). * Remove 'non-sparse' from description of flink:vkGetBufferMemoryRequirements and flink:vkGetImageMemoryRequirements (public issue 257). * Remove ename:VK_ERROR_LAYER_NOT_PRESENT error code from flink:vkCreateDevice (public issue 259). * Change "must not" to "should not" in constraint on when flink:vkAcquireNextImageKHR is called in the +VK_KHR_swapchain+ branch (public issue 262). * Change type of flink:vkCmdUpdateBuffer::pname:pData from basetype:uint32_t* to basetype:void* (public issue 263). * Change should: to must: in description of where additional segments are placed in the <<[tessellation-tessellator-spacing,Tessellator Spacing>> section (public issue 264). Internal Issues: * Normalize the language of all the compute shader built-ins in the <<interfaces-builtin-variables,Built-in Variables>> section (internal issue 323). * Remove definition of presentation engine internal queue lengths associated with ename:VK_PRESENT_MODE_FIFO_KHR and ename:VK_PRESENT_MODE_FIFO_RELAXED_KHR in the <<Window System Integration,wsi>> chapter (internal issue 374). * The language of a Note was too broad, and implied that loaders for a given OS would statically export functions for WSI extensions that weren't relevant to (or supported on) the OS. Also, removed "Khronos-provided" since the Android loader isn't (internal issue 380) Other Commits: * Add ename:VK_INCOMPLETE to list of return values for flink:vkGetPipelineCacheData. Spec says this value is returnable, but it wasn't listed in the error codes. * Fix "correponds" typo in member definitions for slink:VkSubpassDescription.

Change log for February 25, 2015 Vulkan 1.0.4 spec update: * Bump API patch number from 3 to 4 for the first public update to the spec. Add patch number to the spec title (this will be done automatically from XML, later). * Fixes for numerous editorial issues. Regularize descriptions of variable-length array queries. Properly tag enumerants so they come out in the right font (many were mislabeled in usage tags in vk.xml, or not tagged). Spelling and markup corrections (public issue 4). * Fix typos and clearly separate description of different types of memory areas (public issue 5). * Use standards-compliant preprocessor guard symbols on headers (public issue 7). * Note that Github users can't currently set labels on issues, and recommend a fallback approach (public issue 15). * Use latexmath prefix on len= attributes (public issue 29). * Make flink:vkCmdUpdateBuffer pname:dataSize limit consistent (public issue 65). * Add VK_KHR_mirror_clamp_to_edge extension to core API branch, as an optional feature not introducing new commands or enums (internal issue 104). * Cleanup invariance language inherited from the GL specification to not refer to nonexistent (GL-specific) state (internal issue 111). * Modify the flink:vkCmdDrawIndexed pname:vertexOffset definition to not be the "base offset within the index buffer" but rather the "value added to the vertex index before indexing into the vertex buffer" (internal issue 118). * Fix drawing chapter in the "Programmable Primitive Shading" section where it described categories of drawing commands. It referenced flink:vkCmdDrawIndexed twice. Replace the second reference with flink:vkCmdDrawIndexedIndirect (internal issue 119). * Typo fixed in <<sparsememory-examples-advanced,Advanced Sparse Resources>> sparse memory example (internal issue 122). * Add flink:VkDisplayPlaneAlphaFlagsKHR to <require> section of VK_KHR_display extension (internal issue 125) * Add missing optional="false,true" to flink:vkGetImageSparseMemoryRequirements pname:pSparseMemoryRequirementCount parameter (internal issue 132) * Rename ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CREATE_INFO_EXT to ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CALLBACK_CREATE_INFO_EXT (internal issue 133) * Fix a handful of broken cross-references in the <<samplers,Samplers>> chapter (internal issue 134). * Fix "Input Attachement" GLSL example to use correct syntax (internal issue 135). * Update XML schema and documentation to accomodate recently added attributes for validity. Add some introductory material describing design choices and pointing to the public repository to file issues. * Put include of validity in the core spec extensions chapter on its own line, so that asciidoc is happy. * Fix vertexOffset language to specify that it's the value added to the vertex index before indexing into the vertex buffer, not the base offset within the index buffer. * Fix error in the description of flink:vkCmdNextSubpass.

* If pname:image was created with a sharing mode of ename:VK_SHARING_MODE_CONCURRENT, pname:srcQueueFamilyIndex and pname:dstQueueFamilyIndex must: both be ename:VK_QUEUE_FAMILY_IGNORED
* If pname:image was created with a sharing mode of ename:VK_SHARING_MODE_EXCLUSIVE, pname:srcQueueFamilyIndex and pname:dstQueueFamilyIndex must: either both be ename:VK_QUEUE_FAMILY_IGNORED, or both be a valid queue family (see <<devsandqueues-queueprops>>)

* If pname:image was created with a sharing mode of ename:VK_SHARING_MODE_EXCLUSIVE, and pname:srcQueueFamilyIndex and pname:dstQueueFamilyIndex are valid queue families, at least one of them must: be the same as the family of the queue that will execute this barrier
Change log for April 15, 2016 Vulkan 1.0.10 spec update: * Bump API patch number and header version number to 10 for this update. Github Issues: * Slightly tweak the <<memory-allocation,Host Memory>> allocator language so that an application wrapping the standard C alloc/free/realloc functions is still correct - the previous language was too strong with regards to freeing memory. Also made certain scenarios clearer - an implementation may now continue without error if an allocation failed and it is able to continue correctly (public issue 21). * Require that etext:VK_*_CREATE_SPARSE_BINDING_BIT is set when the corresponding etext:VK_*_CREATE_SPARSE_RESIDENCY_BIT is used, in the <<sparsememory-miptail,Mip Tail Regions>> section and related commands flink:vkCreateBuffer and flink:vkCreateImage (public issue 84). * Update the <<features,Features, Limits, and Formats>> chapter to clarify interactions between optional features and dynamic state for the pname:depthBiasClamp and pname:wideLines features (public issue 89). * Describe the code:WorkgroupSize builtin in the <<interfaces-builtin-variables,Built-In Variables>> section, and update the <<compute-shaders,Compute Shaders>> section to further clarify how to set the number of workgroups to execute in a compute shader (public issue 145). * Use the term *image subresource* everywhere instead of *subresource*, except for the special case of *host-accessible subresource*, which may be either an image subresource or buffer range (public issue 120) * Add a note to the <<features,Features, Limits, and Formats>> section about extensibility of structures (Public issue 165). * Fix return code flink:vkAcquireNextImageKHR when the timeout parameter is 0 to ename:VK_NOT_READY instead of ename:VK_TIMEOUT (public issue 170). * Fix typo in slink:VkLayerProperties::pname:apiVersion field (public issue 172). Internal Issues: * Fix a few minor internally-detected typos. * Minor formatting tweaks to pseudocode in the <<resources,Resource Creation>> chapter (internal issue 179). * Fix typo in the definition of point sampling for elink:VkCullModeFlagBits (internal issue 268).

* If either pname:oldLayout or pname:newLayout is ename:VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL then pname:image must: have been created with ename:VK_IMAGE_USAGE_TRANSFER_DST_BIT set
