+24 February 2017. Summary of changes for version 20170224:
+
+
+1) ACPICA kernel-resident subsystem:
+
+Interpreter: Fixed two issues with the control method return value auto-
+repair feature, where an attempt to double-delete an internal object 
+could result in an ACPICA warning (for _CID repair and others). No fault 
+occurs, however, because the attempted deletion (actually a release to an 
+internal cache) is detected and ignored via object poisoning.
+
+Debugger: Fixed an AML interpreter mutex issue during the single stepping 
+of control methods. If certain debugger commands are executed during 
+stepping, a mutex aquire/release error could occur. Lv Zheng.
+
+Fixed some issues generating ACPICA with the Intel C compiler by 
+restoring the original behavior and compiler-specific include file in 
+acenv.h. Lv Zheng.
+
+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: 141.7K Code, 58.5K Data, 200.2K Total
+    Debug Version:     207.5K Code, 82.7K Data, 290.2K Total
+  Previous Release:
+    Non-Debug Version: 137.4K Code, 52.6K Data, 190.0K Total
+    Debug Version:     201.5K Code, 82.2K Data, 283.7K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL/Disassembler: A preliminary version of a new ASL-to-ASL+ conversion 
+tool has been designed, implemented, and included in this release. The 
+key feature of this utility is that the original comments within the 
+input ASL file are preserved during the conversion process, and included 
+within the converted ASL+ file -- thus creating a transparent conversion 
+of existing ASL files to ASL+ (ASL 2.0). Erik Schmauss.
+
+    Usage: iasl -ca <ASL-filename>  // Output is a .dsl file with 
+converted code
+
+iASL/Disassembler: Improved the detection and correct disassembly of 
+Switch/Case operators. This feature detects sequences of if/elseif/else 
+operators that originated from ASL Switch/Case/Default operators and 
+emits the original operators. David Box.
+
+iASL: Improved the IORT ACPI table support in the following areas. Lv 
+Zheng:
+    Clear MappingOffset if the MappingCount is zero.
+    Fix the disassembly of the SMMU GSU interrupt offset.
+    Update the template file for the IORT table.
+
+Disassembler: Enhanced the detection and disassembly of resource 
+template/descriptor within a Buffer object. An EndTag descriptor is now 
+required to have a zero second byte, since all known ASL compilers emit 
+this. This helps eliminate incorrect decisions when a buffer is 
+disassembled (false positives on resource templates).
