 ----------------------------------------
+20 June 2012. Summary of changes for version 20120620:
+
+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:
+
+Implemented support to expand the "implicit notify" feature to allow multiple 
+devices to be notified by a single GPE. This feature automatically generates a 
+runtime device notification in the absence of a BIOS-provided GPE control 
+method (_Lxx/_Exx) or a host-installed handler for the GPE. Implicit notify is 
+provided by ACPICA for Windows compatibility, and is a workaround for BIOS AML 
+code errors. See the description of the AcpiSetupGpeForWake interface in the 
+APCICA reference. Bob Moore, Rafael Wysocki. ACPICA BZ 918.
+
+Changed some comments and internal function names to simplify and ensure 
+correctness of the Linux code translation. No functional changes.
+
+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:  93.0K Code, 25.1K Data, 118.1K Total
+    Debug Version:     172.7K Code, 73.6K Data, 246.3K Total
+  Current Release:
+    Non-Debug Version:  93.1K Code, 25.1K Data, 118.2K Total
+    Debug Version:     172.9K Code, 73.6K Data, 246.5K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Disassembler: Added support to emit short, commented descriptions for the ACPI 
+predefined names in order to improve the readability of the disassembled 
+output. ACPICA BZ 959. Changes include:
+  1) Emit descriptions for all standard predefined names (_INI, _STA, _PRW, 
+etc.)
+  2) Emit generic descriptions for the special names (_Exx, _Qxx, etc.)
+  3) Emit descriptions for the resource descriptor names (_MIN, _LEN, etc.)
+
+AcpiSrc: Fixed several long-standing Linux code translation issues. Argument 
+descriptions in function headers are now translated properly to lower case and 
+underscores. ACPICA BZ 961. Also fixes translation problems such as these: 
+(old -> new)
+  i_aSL -> iASL
+  00-7_f -> 00-7F
+  16_k -> 16K
+  local_fADT -> local_FADT
+  execute_oSI -> execute_OSI
+
+iASL: Fixed a problem where null bytes were inadvertently emitted into some 
+listing files.
+
+iASL: Added the existing debug options to the standard help screen. There are 
+no longer two different help screens. ACPICA BZ 957.
+
+AcpiHelp: Fixed some typos in the various predefined name descriptions. Also 
+expand some of the descriptions where appropriate.
+
+iASL: Fixed the -ot option (display compile times/statistics). Was not working 
+properly for standard output; only worked for the debug file case.
