 ----------------------------------------
+16 June 2015. Summary of changes for version 20150616:
+
+
+1) ACPICA kernel-resident subsystem:
+
+Across the entire ACPICA source code base, the various macros for the C 
+library functions (such as ACPI_STRLEN, etc.) have been removed and 
+replaced by the standard C library names (strlen, etc.) The original 
+purpose for these macros is no longer applicable. This simplification 
+reduces the number of macros used in the ACPICA source code 
+significantly, improving readability and maintainability.
+
+Implemented support for a new ACPI table, the OSDT. This table, the 
+"override" SDT, can be loaded directly by the host OS at boot time. It 
+enables the replacement of existing namespace objects that were installed 
+via the DSDT and/or SSDTs. The primary purpose for this is to replace 
+buggy or incorrect ASL/AML code obtained via the BIOS. The OSDT is slated 
+for inclusion in a future version of the ACPI Specification. Lv Zheng/Bob 
+Moore.
+
+Added support for systems with (improperly) two FACS tables -- a "32-bit" 
+table (via FADT 32-bit legacy field) and a "64-bit" table (via the 64-bit 
+X field). This change will support both automatically. There continues to 
+be systems found with this issue. This support requires a change to the 
+AcpiSetFirmwareWakingVector interface. Also, a public global variable has 
+been added to allow the host to select which FACS is desired 
+(AcpiGbl_Use32BitFacsAddresses). See the ACPICA reference for more 
+details Lv Zheng.
+
+Added a new feature to allow for systems that do not contain an FACS. 
+Although this is already supported on hardware-reduced platforms, the 
+feature has been extended for all platforms. The reasoning is that we do 
+not want to abort the entire ACPICA initialization just because the 
+system is seriously buggy and has no FACS.
+
+Fixed a problem where the GUID strings for NFIT tables (in acuuid.h) were 
+not correctly transcribed from the ACPI specification in ACPICA version 
+20150515.
+
+Implemented support for the _CLS object in the AcpiGetObjectInfo external 
+interface.
+
+Updated the definitions of the TCPA and TPM2 ACPI tables to the more 
+recent TCG ACPI Specification, December 14, 2014. Table disassembler and 
+compiler also updated. Note: The TCPA "server" table is not supported by 
+the disassembler/table-compiler at this time.
+
+ACPI 6.0: Added definitions for the new GIC version field in the MADT.
+
+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: 100.6K Code, 27.6K Data, 128.2K Total
+    Debug Version:     196.2K Code, 81.0K Data, 277.2K Total
+  Previous Release:
+    Non-Debug Version:  99.9K Code, 27.5K Data, 127.4K Total
+    Debug Version:     195.2K Code, 80.8K Data, 276.0K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Disassembler: Fixed a problem with the new symbolic operator disassembler 
+where incorrect ASL code could be emitted in some cases for the "non-
+commutative" operators -- Subtract, Divide, Modulo, ShiftLeft, and 
+ShiftRight. The actual problem cases seem to be rather unusual in common 
+ASL code, however. David Box.
+
+Modified the linux version of acpidump to obtain ACPI tables from not 
+just /dev/mem (which may not exist) and /sys/firmware/acpi/tables. Lv 
+Zheng.
+
+iASL: Fixed a problem where the user preprocessor output file (.i) 
+contained extra data that was not expected. The compiler was using this 
+file as a temporary file and passed through #line directives in order to 
+keep compiler error messages in sync with the input file and line number 
+across multiple include files. The (.i) is no longer a temporary file as 
+the compiler uses a new, different file for the original purpose.
+
+iASL: Fixed a problem where comments within the original ASL source code 
+file were not passed through to the preprocessor output file, nor any 
+listing files.
+
+iASL: Fixed some issues for the handling of the "#include" preprocessor 
+directive and the similar (but not the same) "Include" ASL operator.
+
+iASL: Add support for the new OSDT in both the disassembler and compiler.
+
+iASL: Fixed a problem with the constant folding support where a Buffer 
+object could be incorrectly generated (incorrectly formed) during a 
+conversion to a Store() operator.
+
+AcpiHelp: Updated for new NFIT GUIDs, "External" AML opcode, and new 
+description text for the _REV predefined name. _REV now permanently 
+returns 2, as per the ACPI 6.0 specification.
+
+Debugger: Enhanced the output of the Debug ASL object for references 
+produced by the Index operator. For Buffers and strings, only output the 
+actual byte pointed to by the index. For packages, only print the single 
+package element decoded by the index. Previously, the entire 
+buffer/string/package was emitted.
+
+iASL/Table-compiler: Fixed a regression where the "generic" data types 
+were no longer recognized, causing errors.
