 ----------------------------------------
+11 July 2012. Summary of changes for version 20120711:
+
+This release is available at https://www.acpica.org/downloads The ACPI 5.0 
+specification is available at www.acpi.info
+
+1) ACPICA Kernel-resident Subsystem:
+
+Fixed a possible fault in the return package object repair code. Fixes a 
+problem that can occur when a lone package object is wrapped with an outer 
+package object in order to force conformance to the ACPI specification. Can 
+affect these predefined names: _ALR, _MLS, _PSS, _TRT, _TSS, _PRT, _HPX, _DLM, 
+_CSD, _PSD, _TSD.
+
+Removed code to disable/enable bus master arbitration (ARB_DIS bit in the 
+PM2_CNT register) in the ACPICA sleep/wake interfaces. Management of the 
+ARB_DIS bit must be implemented in the host-dependent C3 processor power state 
+support. Note, ARB_DIS is obsolete and only applies to older chipsets, both 
+Intel and other vendors. (for Intel: ICH4-M and earlier)
+
+This change removes the code to disable/enable bus master arbitration during 
+suspend/resume. Use of the ARB_DIS bit in the optional PM2_CNT register causes 
+resume problems on some machines. The change has been in use for over seven 
+years within Linux.
+
+Implemented two new external interfaces to support host-directed dynamic ACPI 
+table load and unload. They are intended to simplify the host implementation 
+of hot-plug support:
+  AcpiLoadTable: Load an SSDT from a buffer into the namespace.
+  AcpiUnloadParentTable: Unload an SSDT via a named object owned by the table.
+See the ACPICA reference for additional details. Adds one new file, 
+components/tables/tbxfload.c
+
+Implemented and deployed two new interfaces for errors and warnings that are 
+known to be caused by BIOS/firmware issues:
+  AcpiBiosError: Prints "ACPI Firmware Error" message.
+  AcpiBiosWarning: Prints "ACPI Firmware Warning" message.
+Deployed these new interfaces in the ACPICA Table Manager code for ACPI table 
+and FADT errors. Additional deployment to be completed as appropriate in the 
+future. The associated conditional macros are ACPI_BIOS_ERROR and 
+ACPI_BIOS_WARNING. See the ACPICA reference for additional details. ACPICA BZ 
+843.
+
+Implicit notify support: ensure that no memory allocation occurs within a 
+critical region. This fix moves a memory allocation outside of the time that a 
+spinlock is held. Fixes issues on systems that do not allow this behavior. 
+Jung-uk Kim.
+
+Split exception code utilities and tables into a new file, utilities/utexcep.c
+
+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.
+
+  Previous Release:
+    Non-Debug Version:  93.1K Code, 25.1K Data, 118.2K Total
+    Debug Version:     172.9K Code, 73.6K Data, 246.5K Total
+  Current Release:
+    Non-Debug Version:  93.5K Code, 25.3K Data, 118.8K Total
+    Debug Version:     173.7K Code, 74.0K Data, 247.7K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Fixed a parser problem for hosts where EOF is defined as -1 instead of 
+0. Jung-uk Kim.
+
+Debugger: Enhanced the "tables" command to emit additional information about 
+the current set of ACPI tables, including the owner ID and flags decode.
+
+Debugger: Reimplemented the "unload" command to use the new 
+AcpiUnloadParentTable external interface. This command was disable previously 
+due to need for an unload interface.
+
+AcpiHelp: Added a new option to decode ACPICA exception codes. The -e option 
+will decode 16-bit hex status codes (ACPI_STATUS) to name strings.
