 ----------------------------------------
+13 April 2011. Summary of changes for version 20110413:
+
+1) ACPI CA Core Subsystem:
+
+Implemented support to execute a so-called "orphan" _REG method under the EC 
+device. This change will force the execution of a _REG method underneath the EC 
+device even if there is no corresponding operation region of type 
+EmbeddedControl. Fixes a problem seen on some machines and apparently is 
+compatible with Windows behavior. ACPICA BZ 875.
+
+Added more predefined methods that are eligible for automatic NULL package 
+element removal. This change adds another group of predefined names to the list 
+of names that can be repaired by having NULL package elements dynamically 
+removed. This group are those methods that return a single variable-length 
+package containing simple data types such as integers, buffers, strings. This 
+includes: _ALx, _BCL, _CID,_ DOD, _EDL, _FIX, _PCL, _PLD, _PMD, _PRx, _PSL, _Sx, 
+and _TZD. ACPICA BZ 914.
+
+Split and segregated all internal global lock functions to a new file, evglock.c.
+
+Updated internal address SpaceID for DataTable regions. Moved this internal space 
+id in preparation for ACPI 5.0 changes that will include some new space IDs. This 
+change should not affect user/host code.
+
+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:  89.8K Code, 23.8K Data, 113.6K Total
+    Debug Version:     164.2K Code, 67.9K Data, 232.1K Total

+    Debug Version:     164.5K Code, 68.0K Data, 232.5K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL/DTC: Major update for new grammar features. Allow generic data types in 
+custom ACPI tables. Field names are now optional. Any line can be split to 
+multiple lines using the continuation char (\). Large buffers now use line-
+continuation character(s) and no colon on the continuation lines. See the grammar 
+update in the iASL compiler reference. ACPI BZ 910,911. Lin Ming, Bob Moore.
+
+iASL: Mark ASL "Return()" and the simple "Return" as "Null" return statements. 
+Since the parser stuffs a "zero" as the return value for these statements (due to 
+the underlying AML grammar), they were seen as "return with value" by the iASL 
+semantic checking. They are now seen correctly as "null" return statements.
+
+iASL: Check if a_REG declaration has a corresponding Operation Region. Adds a 
+check for each _REG to ensure that there is in fact a corresponding operation 
+region declaration in the same scope. If not, the _REG method is not very useful 
+since it probably won't be executed. ACPICA BZ 915.
+
+iASL/DTC: Finish support for expression evaluation. Added a new expression parser 
+that implements c-style operator precedence and parenthesization. ACPICA bugzilla 
+908.
+
+Disassembler/DTC: Remove support for () and <> style comments in data tables. Now 
+that DTC has full expression support, we don't want to have comment strings that 
+start with a parentheses or a less-than symbol. Now, only the standard /* and // 
+comments are supported, as well as the bracket [] comments.
+
+AcpiXtract: Fix for RSDP and dynamic SSDT extraction. These tables have "unusual" 
+headers in the acpidump file. Update the header validation to support these 
+tables. Problem introduced in previous AcpiXtract version in the change to 
+support "wrong checksum" error messages emitted by acpidump utility.
+
+iASL: Add a * option to generate all template files (as a synonym for ALL) as in 
+"iasl -T *" or "iasl -T ALL".
+
+iASL/DTC: Do not abort compiler on fatal errors. We do not want to completely 
+abort the compiler on "fatal" errors, simply should abort the current compile. 
+This allows multiple compiles with a single (possibly wildcard) compiler 
+invocation.
