+12 January 2011. Summary of changes for version 20110112:
+
+1) ACPI CA Core Subsystem:
 
-This release is available at www.acpica.org/downloads
+Fixed a race condition between method execution and namespace walks that can 
+possibly cause a fault. The problem was apparently introduced in version 
+20100528 as a result of a performance optimization that reduces the number of 
+namespace walks upon method exit by using the delete_namespace_subtree 
+function instead of the delete_namespace_by_owner function used previously. 
+Bug is a missing namespace lock in the delete_namespace_subtree function. 
+dana.myers@oracle.com
+
+Fixed several issues and a possible fault with the automatic "serialized" 
+method support. History: This support changes a method to "serialized" on the 
+fly if the method generates an AE_ALREADY_EXISTS error, indicating the 
+possibility that it cannot handle reentrancy. This fix repairs a couple of 
+issues seen in the field, especially on machines with many cores:
+
+    1) Delete method children only upon the exit of the last thread,
+       so as to not delete objects out from under other running threads
+      (and possibly causing a fault.)
+    2) Set the "serialized" bit for the method only upon the exit of the
+       Last thread, so as to not cause deadlock when running threads
+       attempt to exit.
+    3) Cleanup the use of the AML "MethodFlags" and internal method flags
+       so that there is no longer any confusion between the two.
+
+    Lin Ming, Bob Moore. Reported by dana.myers@oracle.com.
+
+Debugger: Now lock the namespace for duration of a namespace dump. Prevents 
+issues if the namespace is changing dynamically underneath the debugger. 
+Especially affects temporary namespace nodes, since the debugger displays 
+these also.
+
+Updated the ordering of include files. The ACPICA headers should appear 
+before any compiler-specific headers (stdio.h, etc.) so that acenv.h can set 
+any necessary compiler-specific defines, etc. Affects the ACPI-related tools 
+and utilities.
+
+Updated all ACPICA copyrights and signons to 2011. Added the 2011 copyright 
+to all module headers and signons, including the Linux header. This affects 
+virtually every file in the ACPICA core subsystem, iASL compiler, and all 
+utilities.
+
+Added project files for MS Visual Studio 2008 (VC++ 9.0). The original 
+project files for VC++ 6.0 are now obsolete. New project files can be found 
+under acpica/generate/msvc9. See acpica/generate/msvc9/readme.txt for 
+details.
+
+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 6.0):
+    Non-Debug Version:  89.8K Code, 18.9K Data, 108.7K Total
+    Debug Version:     166.6K Code, 52.1K Data, 218.7K Total
+  Current Release (VC 9.0):
+    Non-Debug Version:  89.7K Code, 23.7K Data, 113.4K Total
+    Debug Version:     163.9K Code, 67.5K Data, 231.4K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Added generic data types to the Data Table compiler. Add "generic" data 
+types such as UINT32, String, Unicode, etc., to simplify the generation of 
+platform-defined tables such as UEFI. Lin Ming.
+
+iASL: Added listing support for the Data Table Compiler. Adds listing support 
+(-l) to display actual binary output for each line of input code.
