+// These are the version numbers used to version the API between Ansel SDK and the driver.
+// The driver provides backwards compatibility to all MINOR versions that are equal or lower
+// but requires matching MAJOR version. This effectively means that MAJOR version number will *not*
+// change because this would mean that a newer driver would stop supporting older Ansel SDKs.
+// The driver does however not provide forwards compatibility, i.e. when a new interface or change 
+// in behavior is introduced between Ansel SDK and the driver the MINOR version is incremented. This
+// means that new driver supporting this new MINOR version is required. To track this relationship 
+// we use the MINIMUM_DRIVER_VERSION define. When you increment MINOR version you need to adjust the
+// MINIMUM_DRIVER_VERSION as well. While a public driver hasn't been finalized use our internal 
+// release tags to identify it (like 378.GA2).

+// The lines below are automatically updated by build agents. Please don't touch.
