-27 May 2011. Summary of changes for version 20110527:
+23 June 2011. Summary of changes for version 20110623:
+
+1) ACPI CA Core Subsystem:
+
+Updated the predefined name repair mechanism to not attempt repair of a _TSS 
+return object if a _PSS object is present. We can only sort the _TSS return 
+package if there is no _PSS within the same scope. This is because if _PSS is 
+present, the ACPI specification dictates that the _TSS Power Dissipation field 
+is to be ignored, and therefore some BIOSs leave garbage values in the _TSS 
+Power field(s). In this case, it is best to just return the _TSS package as-
+is. Reported by, and fixed with assistance from Fenghua Yu.
+
+Added an option to globally disable the control method return value validation 
+and repair. This runtime option can be used to disable return value repair if 
+this is causing a problem on a particular machine. Also added an option to 
+AcpiExec (-dr) to set this disable flag.
+
+All makefiles and project files: Major changes to improve generation of ACPICA 
+tools. ACPICA BZ 912:
+    Reduce default optimization levels to improve compatibility
+    For Linux, add strict-aliasing=0 for gcc 4
+    Cleanup and simplify use of command line defines
+    Cleanup multithread library support
+    Improve usage messages
+
+Linux-specific header: update handling of THREAD_ID and pthread. For the 32-
+bit case, improve casting to eliminate possible warnings, especially with the 
+acpica tools.
+
+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 (VC 9.0):
+    Non-Debug Version:  90.1K Code, 23.9K Data, 114.0K Total
+    Debug Version:     165.6K Code, 68.4K Data, 234.0K Total
+  Current Release (VC 9.0):
+    Non-Debug Version:  90.2K Code, 23.9K Data, 114.1K Total
+    Debug Version:     165.6K Code, 68.4K Data, 234.0K Total
+
+2) iASL Compiler/Disassembler and Tools:
 
-This release is available at www.acpica.org/downloads
+With this release, a new utility named "acpihelp" has been added to the ACPICA 
+package. This utility summarizes the ACPI specification chapters for the ASL 
+and AML languages. It generates under Linux/Unix as well as Windows, and 
+provides the following functionality:
+    Find/display ASL operator(s) -- with description and syntax.
+    Find/display ASL keyword(s) -- with exact spelling and descriptions.
+    Find/display ACPI predefined name(s) -- with description, number
+        of arguments, and the return value data type.
+    Find/display AML opcode name(s) -- with opcode, arguments, and grammar.
+    Decode/display AML opcode -- with opcode name, arguments, and grammar.
+
+Service Layers: Make multi-thread support configurable. Conditionally compile 
+the multi-thread support so that threading libraries will not be linked if not 
+necessary. The only tool that requires multi-thread support is AcpiExec.
+
+iASL: Update yyerrror/AslCompilerError for "const" errors. Newer versions of 
+Bison appear to want the interface to yyerror to be a const char * (or at 
+least this is a problem when generating iASL on some systems.) ACPICA BZ 923 
+Pierre Lejeune.
+
+Tools: Fix for systems where O_BINARY is not defined. Only used for Windows 
+versions of the tools.
