+18 May 2012. Summary of changes for version 20120518:
+
+
+1) ACPICA Core Subsystem:
+
+Added a new OSL interface, AcpiOsWaitEventsComplete. This interface is defined 
+to block until asynchronous events such as notifies and GPEs have completed. 
+Within ACPICA, it is only called before a notify or GPE handler is 
+removed/uninstalled. It also may be useful for the host OS within related 
+drivers such as the Embedded Controller driver. See the ACPICA reference for 
+additional information. ACPICA BZ 868.
+
+ACPI Tables: Added a new error message for a possible overflow failure during 
+the conversion of FADT 32-bit legacy register addresses to internal common 64-
+bit GAS structure representation. The GAS has a one-byte "bit length" field, 
+thus limiting the register length to 255 bits. ACPICA BZ 953.
+
+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:  92.9K Code, 25.0K Data, 117.9K Total
+    Debug Version:     172.6K Code, 73.4K Data, 246.0K Total
+  Current Release:
+    Non-Debug Version:  93.0K Code, 25.1K Data, 118.1K Total
+    Debug Version:     172.7K Code, 73.6K Data, 246.3K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Added the ACPI 5.0 "PCC" keyword for use in the Register() ASL macro. 
+This keyword was added late in the ACPI 5.0 release cycle and was not 
+implemented until now.
+
+Disassembler: Added support for Operation Region externals. Adds missing 
+support for operation regions that are defined in another table, and 
+referenced locally via a Field or BankField ASL operator. Now generates the 
+correct External statement.
+
+Disassembler: Several additional fixes for the External() statement generation 
+related to some ASL operators. Also, order the External() statements 
+alphabetically in the disassembler output. Fixes the External() generation for 
+the Create* field, Alias, and Scope operators:
+ 1) Create* buffer field operators - fix type mismatch warning on disassembly
+ 2) Alias - implement missing External support
+ 3) Scope - fix to make sure all necessary externals are emitted.
+
+iASL: Improved pathname support. For include files, merge the prefix pathname 
+with the file pathname and eliminate unnecessary components. Convert 
+backslashes in all pathnames to forward slashes, for readability. Include file 
+pathname changes affect both #include and Include() type operators.
+
+iASL/DTC/Preprocessor: Gracefully handle early EOF. Handle an EOF at the end 
+of a valid line by inserting a newline and then returning the EOF during the 
+next call to GetNextLine. Prevents the line from being ignored due to EOF 
+condition.
+
+iASL: Implemented some changes to enhance the IDE support (-vi option.) Error 
+and Warning messages are now correctly recognized for both the source code 
+browser and the global error and warning counts.
