+22 December 2016. Summary of changes for version 20161222:
+
+
+1) ACPICA kernel-resident subsystem:
+
+AML Debugger: Implemented a new mechanism to simplify and enhance 
+debugger integration into all environments, including kernel debuggers 
+and user-space utilities, as well as remote debug services. This 
+mechanism essentially consists of new OSL interfaces to support debugger 
+initialization/termination, as well as wait/notify interfaces to perform 
+the debugger handshake with the host. Lv Zheng.
+
+    New OSL interfaces:
+        AcpiOsInitializeDebugger (void)
+        AcpiOsTerminateDebugger (void)
+        AcpiOsWaitCommandReady (void)
+        AcpiOsNotifyCommandComplete (void)
+
+    New OS services layer:
+        osgendbg.c -- Example implementation, and used for AcpiExec
+
+Update for Generic Address Space (GAS) support: Although the AccessWidth 
+and/or BitOffset fields of the GAS are not often used, this change now 
+fully supports these fields. This affects the internal support for FADT 
+registers, registers in other ACPI data tables, and the AcpiRead and 
+AcpiWrite public interfaces. Lv Zheng.
+
+Sleep support: In order to simplify integration of ACPI sleep for the 
+various host operating systems, a new OSL interface has been introduced. 
+AcpiOsEnterSleep allows the host to perform any required operations 
+before the final write to the sleep control register(s) is performed by 
+ACPICA. Lv Zheng.
+
+    New OSL interface:
+        AcpiOsEnterSleep(SleepState, RegisterAValue, RegisterBValue)
+
+    Called from these internal interfaces:
+        AcpiHwLegacySleep
+        AcpiHwExtendedSleep
+
+EFI support: Added a very small EFI/ACPICA example application. Provides 
+a simple demo for EFI integration, as well as assisting with resolution 
+of issues related to customer ACPICA/EFI integration. Lv Zheng. See:
+
+    source/tools/efihello/efihello.c
+
+Local C library: Implemented several new functions to enhance ACPICA 
+portability, for environments where these clib functions are not 
+available (such as EFI). Lv Zheng:
+    putchar
+    getchar
+    strpbrk
+    strtok
+    memmove
+
+Fixed a regression where occasionally a valid resource descriptor was 
+incorrectly detected as invalid at runtime, and a 
+AE_AML_NO_RESOURCE_END_TAG was returned.
+
+Fixed a problem with the recently implemented support that enables 
+control method invocations as Target operands to many ASL operators. 
+Warnings of this form: "Needed type [Reference], found [Processor]" were 
+seen at runtime for some method invocations.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
+debug version of the code includes the debug output trace mechanism and 
+has a much larger code and data size.
+
+  Current Release:
+    Non-Debug Version: 141.5K Code, 58.5K Data, 200.0K Total
+    Debug Version:     201.7K Code, 82.7K Data, 284.4K Total
+  Previous Release:
+    Non-Debug Version: 140.5K Code, 58.5K Data, 198.9K Total
+    Debug Version:     201.3K Code, 82.7K Data, 284.0K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Disassembler: Enhanced output by adding the capability to detect and 
+disassemble ASL Switch/Case statements back to the original ASL source 
+code instead of if/else blocks. David Box.
+
+AcpiHelp: Split a large file into separate files based upon 
+functionality/purpose. New files are:
+    ahaml.c
+    ahasl.c
