  "message": "Control timeline semaphore emulation at runtime, remove extension layer.\n\n* The `VK_LAYER_KHRONOS_timeline_semaphore` extension layer may still be used, but it is no longer required. To simplify maintenance, this change removes IREE\u0027s build system helpers and documentation for it.\n* The `integrations/tensorflow/e2e/e2e_control_flow_test_tf_iree_vulkan` test required bumping `kMaxInFlightFenceCount` to remain passing when using IREE\u0027s new timeline semaphore emulation.\n* Updated SwiftShader instructions on Windows now that the Linux-only extension layer is not required with it.\n",
