+23 August 2013. Summary of changes for version 20130823:
+
+1) ACPICA kernel-resident subsystem:
+
+Implemented support for host-installed System Control Interrupt (SCI) 
+handlers. Certain ACPI functionality requires the host to handle raw 
+SCIs. For example, the "SCI Doorbell" that is defined for memory power 
+state support requires the host device driver to handle SCIs to examine 
+if the doorbell has been activated. Multiple SCI handlers can be 
+installed to allow for future expansion. New external interfaces are 
+AcpiInstallSciHandler, AcpiRemoveSciHandler; see the ACPICA reference for 
+details. Lv Zheng, Bob Moore. ACPICA BZ 1032.
+
+Operation region support: Never locally free the handler "context" 
+pointer. This change removes some dangerous code that attempts to free 
+the handler context pointer in some (rare) circumstances. The owner of 
+the handler owns this pointer and the ACPICA code should never touch it. 
+Although not seen to be an issue in any kernel, it did show up as a 
+problem (fault) under AcpiExec. Also, set the internal storage field for 
+the context pointer to zero when the region is deactivated, simply for 
+sanity. David Box. ACPICA BZ 1039.
+
+AcpiRead: On error, do not modify the return value target location. If an 
+error happens in the middle of a split 32/32 64-bit I/O operation, do not 
+modify the target of the return value pointer. Makes the code consistent 
+with the rest of ACPICA. Bjorn Helgaas.
+
+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:  96.7K Code, 27.1K Data, 123.9K Total
+    Debug Version:     184.4K Code, 76.8K Data, 261.2K Total
+  Previous Release:
+    Non-Debug Version:  96.2K Code, 27.1K Data, 123.3K Total
+    Debug Version:     185.4K Code, 77.1K Data, 262.5K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+AcpiDump: Implemented several new features and fixed some problems:
+1) Added support to dump the RSDP, RSDT, and XSDT tables.
+2) Added support for multiple table instances (SSDT, UEFI).
+3) Added option to dump "customized" (overridden) tables (-c).
+4) Fixed a problem where some table filenames were improperly 
+constructed.
+5) Improved some error messages, removed some unnecessary messages.
+
+iASL: Implemented additional support for disassembly of ACPI tables that 
+contain invocations of external control methods. The -fe<file> option 
+allows the import of a file that specifies the external methods along 
+with the required number of arguments for each -- allowing for the 
+correct disassembly of the table. This is a workaround for a limitation 
+of AML code where the disassembler often cannot determine the number of 
+arguments required for an external control method and generates incorrect 
+ASL code. See the iASL reference for details. ACPICA BZ 1030.
+
+Debugger: Implemented a new command (paths) that displays the full 
+pathnames (namepaths) and object types of all objects in the namespace. 
+This is an alternative to the namespace command.
+
+Debugger: Implemented a new command (sci) that invokes the SCI dispatch 
+mechanism and any installed handlers.
+
+iASL: Fixed a possible segfault for "too many parent prefixes" condition. 
+This can occur if there are too many parent prefixes in a namepath (for 
+example, ^^^^^^PCI0.ECRD). ACPICA BZ 1035.
+
+Application OSLs: Set the return value for the PCI read functions. These 
+functions simply return AE_OK, but should set the return value to zero 
+also. This change implements this. ACPICA BZ 1038.
+
+Debugger: Prevent possible command line buffer overflow. Increase the 
+size of a couple of the debugger line buffers, and ensure that overflow 
+cannot happen. ACPICA BZ 1037.
+
+iASL: Changed to abort immediately on serious errors during the parsing 
+phase. Due to the nature of ASL, there is no point in attempting to 
+compile these types of errors, and they typically end up causing a 
+cascade of hundreds of errors which obscure the original problem.
