+Change log for September 5, 2017 Vulkan 1.0.60 spec update:
+
+  * Bump API patch number and header version number to 60 for this update.
+
+Github Issues:
+
+  * Document that <<queries-timestamps, Timestamp Queries>> can only be
+    meaningfully compared when they are written from the same queue (public
+    issue 216).
+  * Document that the `<extension>` tag `type` attribute is required for
+    non-disabled extensions (derived from, but does not close public issue
+    354).
+  * Clean up registry schema length attribute descriptions to be consistent
+    and correct (public issue 555).
+
+Internal Issues:
+
+  * Replace as much of the hand-written extension appendix metadata as
+    possible with asciidoc includes generated from corresponding attributes
+    of +vk.xml+, and enhance the style guide to match. This avoids
+    inconsistencies between +vk.xml+ and the appendices, and produces a more
+    uniform style (internal issue 137).
+  * Remove the generated extDependency.{py,sh} files from the tree and
+    create them dynamically on demand instead, reducing merge conflicts
+    (internal issue 713).
+  * Add a prototype tool for generating in-place difference markup for
+    sections guarded by asciidoc conditionals, and new syntax for open
+    blocks to support it (internal issue 833).
+  * Remove unnecessary restriction of etext:*SYNC_FD_BIT_KHR external handle
+    types to the same physical device in the
+    slink:VkPhysicalDeviceIDPropertiesKHR,
+    flink:VkImportMemoryWin32HandleInfoKHR,
+    slink:VkImportFenceWin32HandleInfoKHR, slink:VkImportFenceFdInfoKHR,
+    slink:VkImportSemaphoreWin32HandleInfoKHR,
+    slink:VkImportSemaphoreFdInfoKHR
+    <<external-memory-handle-types-compatibility, External memory handle
+    types compatibility>>, <<external-semaphore-handle-types-compatibility,
+    External semaphore handle types compatibility>>, and
+    <<external-fence-handle-types-compatibility, External fence handle types
+    compatibility>> sections (internal issue 956).
+
+Other Issues:
+
+  * Remove dependency of +VK_KHX_device_group+ on +VK_KHR_swapchain+ (there
+    is an interaction, but not a strict dependency), and add a new
+    `extension` attribute to the `<require` XML tag to allow classifying a
+    subset of interfaces of an extension as requiring another extension.
+    Update the registry schema and documentation accordingly.
+
+New Extensions:
+
+  * `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask`
+    GLSL extension)
+  * `VK_EXT_sample_locations`
+  * `VK_EXT_validation_cache`
