Change log for June 20, 2020 Vulkan 1.2.145 spec update:
 * Update release number to 145 for this update. Github Issues: * Fix `<<VK_EXT_conservative_rasterization>>` interactions with external SPIR-V and GLSL functionality in the extension appendix (public issue 1288). Internal Issues: * Break SPIR-V validation into two sections, <<spirvenv-module-validation-standalone, Standalone SPIR-V Validation>> and <<spirvenv-module-validation-runtime, Runtime SPIR-V Validation>> (internal issue 1598). * Add VkFormat enums for ASTC 3D formats to `vk.xml`. These values are slotted into the reserved, and still disabled extension 289. They will not appear in the published `vulkan_core.h` header and there is no published extension utilizing them, but this allows external projects such as KTX2 to use these values as part of their internal cross-API formats by generating a header including this disabled extension (internal merge requests 1662, 2216). * Synchronize that shader binding table accesses from ray tracing pipelines should be synchronized with the ename:VK_PIPELINE_STAGE_RAY_TRACING_SHADER_BIT_KHR pipeline stage and an access mask of ename:VK_ACCESS_SHADER_READ_BIT (internal issue 1749). * Validate that 3D image views are not used as attachments in slink:VkFramebufferCreateInfo and slink:VkRenderPassAttachmentBeginInfo (internal issue 2142). * Increase the number of conditions recognized as build errors by the valid usage extraction plugin (internal issue 2215). * Relax slink:VkImportAndroidHardwareBufferInfoANDROID valid usage statement 01881 to support external formats (internal issue 2220). * Clearly define what "`optional capabilities`" means in the <<spirvenv-capabilities, Capabilities>> section, and specify that if *any* of the required core versions and/or extensions for a capability is enabled, then it is valid to use that capability (internal merge request 3827). * Add ename:VK_FORMAT_B5G5R5_UNORM_PACK16 and ename:VK_FORMAT_B5G5R5A1_UNORM_PACK16 to `<<VK_EXT_custom_border_color>>` as exceptions when <features-customBorderColorWithoutFormat>> is enabled (internal merge request 3833). * Add new <<spirvenv-format-type-matching, Image Format and Type Matching>> section and refer to it from elsewhere in the spec, clarifying rules regarding types for image operations (internal merge request 3916). * Fix typo sname:VkImageFormatProperties -> slink:VkFormatProperties (internal merge request 3921). * Move <<sparsememory-examples, sparse image examples>> to the Vulkan Guide (internal merge request 3930). * Fix typo in slink:VkAccelerationStructureBuildOffsetInfoKHR valid usage statement 03553 (internal merge request 3938). * Support <remove> tags for extending enumerants in XML (internal merge request 3942). New Extensions: * `<<VK_EXT_extended_dynamic_state>>`

Change log for June 20, 2020 Vulkan 1.2.145 spec update:
16+
17+
* Update release number to 145 for this update.
18+
19+
Github Issues:
20+
21+
* Fix `<<VK_EXT_conservative_rasterization>>` interactions with external
22+
SPIR-V and GLSL functionality in the extension appendix (public issue
23+
1288).
24+
25+
Internal Issues:
26+
27+
* Break SPIR-V validation into two sections,
28+
<<spirvenv-module-validation-standalone, Standalone SPIR-V Validation>>
29+
and <<spirvenv-module-validation-runtime, Runtime SPIR-V Validation>>
30+
(internal issue 1598).
31+
* Add VkFormat enums for ASTC 3D formats to `vk.xml`. These values are
32+
slotted into the reserved, and still disabled extension 289. They will
33+
not appear in the published `vulkan_core.h` header and there is no
34+
published extension utilizing them, but this allows external projects
35+
such as KTX2 to use these values as part of their internal cross-API
36+
formats by generating a header including this disabled extension
37+
(internal merge requests 1662, 2216).
38+
* Synchronize that shader binding table accesses from ray tracing
39+
pipelines should be synchronized with the
40+
ename:VK_PIPELINE_STAGE_RAY_TRACING_SHADER_BIT_KHR pipeline stage and an
41+
access mask of ename:VK_ACCESS_SHADER_READ_BIT (internal issue 1749).
42+
* Validate that 3D image views are not used as attachments in
43+
slink:VkFramebufferCreateInfo and slink:VkRenderPassAttachmentBeginInfo
44+
(internal issue 2142).
45+
* Increase the number of conditions recognized as build errors by the
46+
valid usage extraction plugin (internal issue 2215).
47+
* Relax slink:VkImportAndroidHardwareBufferInfoANDROID valid usage
48+
statement 01881 to support external formats (internal issue 2220).
49+
* Clearly define what "`optional capabilities`" means in the
50+
<<spirvenv-capabilities, Capabilities>> section, and specify that if
51+
*any* of the required core versions and/or extensions for a capability
52+
is enabled, then it is valid to use that capability (internal merge
53+
request 3827).
54+
* Add ename:VK_FORMAT_B5G5R5_UNORM_PACK16 and
55+
ename:VK_FORMAT_B5G5R5A1_UNORM_PACK16 to
56+
`<<VK_EXT_custom_border_color>>` as exceptions when
57+
<features-customBorderColorWithoutFormat>> is enabled (internal merge
58+
request 3833).
59+
* Add new <<spirvenv-format-type-matching, Image Format and Type
60+
Matching>> section and refer to it from elsewhere in the spec,
61+
clarifying rules regarding types for image operations (internal merge
62+
request 3916).
63+
* Fix typo sname:VkImageFormatProperties -> slink:VkFormatProperties
64+
(internal merge request 3921).
65+
* Move <<sparsememory-examples, sparse image examples>> to the Vulkan
66+
Guide (internal merge request 3930).
67+
* Fix typo in slink:VkAccelerationStructureBuildOffsetInfoKHR valid usage
68+
statement 03553 (internal merge request 3938).
69+
* Support <remove> tags for extending enumerants in XML (internal merge
70+
