 ----------------------------------------
+26 September 2014. Summary of changes for version 20140926:
+
+1) ACPICA kernel-resident subsystem:
+
+Updated the GPIO operation region handler interface (GeneralPurposeIo). 
+In order to support GPIO Connection objects with multiple pins, along 
+with the related Field objects, the following changes to the interface 
+have been made: The Address is now defined to be the offset in bits of 
+the field unit from the previous invocation of a Connection. It can be 
+viewed as a "Pin Number Index" into the connection resource descriptor. 
+The BitWidth is the exact bit width of the field. It is usually one bit, 
+but not always. See the ACPICA reference guide (section 8.8.6.2.1) for 
+additional information and examples.
+
+GPE support: During ACPICA/GPE initialization, ensure that all GPEs with 
+corresponding _Lxx/_Exx methods are disabled (they may have been enabled 
+by the firmware), so that they cannot fire until they are enabled via 
+AcpiUpdateAllGpes. Rafael J. Wysocki.
+
+Added a new return flag for the Event/GPE status interfaces -- 
+AcpiGetEventStatus and AcpiGetGpeStatus. The new 
+ACPI_EVENT_FLAGS_HAS_HANDLER flag is used to indicate that the event or 
+GPE currently has a handler associated with it, and can thus actually 
+affect the system. 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:  99.1K Code, 27.3K Data, 126.4K Total
+    Debug Version:     192.8K Code, 79.9K Data, 272.7K Total
+  Previous Release:
+    Non-Debug Version:  98.8K Code, 27.3K Data, 126.1K Total
+    Debug Version:     192.1K Code, 79.8K Data, 271.9K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Fixed a memory allocation/free regression introduced in 20140828 
+that could cause the compiler to crash. This was introduced inadvertently 
+during the effort to eliminate compiler memory leaks. ACPICA BZ 1111, 
+1113.
+
+iASL: Removed two error messages that have been found to create false 
+positives, until they can be fixed and fully validated (ACPICA BZ 1112):
+1) Illegal forward reference within a method
+2) Illegal reference across two methods
+
+iASL: Implemented a new option (-lm) to create a hardware mapping file 
+that summarizes all GPIO, I2C, SPI, and UART connections. This option 
+works for both the compiler and disassembler. See the iASL compiler user 
+guide for additional information and examples (section 6.4.6).
+
+AcpiDump: Added support for the version 1 (ACPI 1.0) RSDP in addition to 
+version 2. This corrects the AE_BAD_HEADER exception seen on systems with 
+a version 1 RSDP. Lv Zheng ACPICA BZ 1097.
+
+AcpiExec: For Unix versions, don't attempt to put STDIN into raw mode 
+unless STDIN is actually a terminal. Assists with batch-mode processing. 
+ACPICA BZ 1114.
+
+Disassembler/AcpiHelp: Added another large group of recognized _HID 
+values.
