 ----------------------------------------
+04 March 2010. Summary of changes for version 20100304:
+
+1) ACPI CA Core Subsystem:
+
+Fixed a possible problem with the AML Mutex handling function 
+AcpiExReleaseMutex where the function could fault under the very rare 
+condition when the interpreter has blocked, the interpreter lock is released, 
+the interpreter is then reentered via the same thread, and attempts to 
+acquire an AML mutex that was previously acquired. FreeBSD report 140979. Lin 
+Ming.
+
+Implemented additional configuration support for the AML "Debug Object". 
+Output from the debug object can now be enabled via a global variable, 
+AcpiGbl_EnableAmlDebugObject. This will assist with remote machine debugging. 
+This debug output is now available in the release version of ACPICA instead 
+of just the debug version. Also, the entire debug output module can now be 
+configured out of the ACPICA build if desired. One new file added, 
+executer/exdebug.c. Lin Ming, Bob Moore.
+
+Added header support for the ACPI MCHI table (Management Controller Host 
+Interface Table). This table was added in ACPI 4.0, but the defining document 
+has only recently become available.
+
+Standardized output of integer values for ACPICA warnings/errors. Always use 
+0x prefix for hex output, always use %u for unsigned integer decimal output. 
+Affects ACPI_INFO, ACPI_ERROR, ACPI_EXCEPTION, and ACPI_WARNING (about 400 
+invocations.) These invocations were converted from the original 
+ACPI_DEBUG_PRINT invocations and were not consistent. ACPICA BZ 835.
+
+Example Code and Data Size: These are the sizes for the OS-independent 
+acpica.lib produced by the Microsoft Visual C++ 6.0 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:  87.1K Code, 18.0K Data, 105.1K Total
+    Debug Version:     163.5K Code, 50.9K Data, 214.4K Total
+  Current Release:
+    Non-Debug Version:  87.5K Code, 18.4K Data, 105.9K Total
+    Debug Version:     163.4K Code, 51.1K Data, 214.5K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Implemented typechecking support for static (non-control method) 
+predefined named objects that are declared with the Name() operator. For 
+example, the type of this object is now validated to be of type Integer: 
+Name(_BBN, 1). This change migrates the compiler to using the core predefined 
+name table instead of maintaining a local version. Added a new file, 
+aslpredef.c. ACPICA BZ 832.
+
+Disassembler: Added support for the ACPI 4.0 MCHI table.
