+28 July 2017. Summary of changes for version 20170728:
+
+
+1) ACPICA kernel-resident subsystem:
+
+Fixed a regression seen with small resource descriptors that could cause 
+an inadvertent AE_AML_NO_RESOURCE_END_TAG exception.
+
+AML interpreter: Implemented a new feature that allows forward references 
+from individual named references within package objects that are 
+contained within blocks of "module-level code". This provides 
+compatibility with other ACPI implementations and supports existing 
+firmware that depends on this feature. Example:
+
+    Name (ABCD, 1)
+    If (ABCD)                       /* An If() at module-level */
+    {
+        Name (PKG1, Package()
+        {
+            INT1                    /* Forward reference to object INT1 
+*/
+        })
+        Name (INT1, 0x1234)
+    }
+
+AML Interpreter: Fixed a problem with the Alias() operator where aliases 
+to some ASL objects were not handled properly. Objects affected are: 
+Mutex, Event, and OperationRegion.
+
+AML Debugger: Enhanced to properly handle AML Alias objects. These 
+objects have one level of indirection which was not fully supported by 
+the debugger.
+
+Table Manager: Added support to detect and ignore duplicate SSDTs within 
+the XSDT/RSDT. This error in the XSDT has been seen in the field.
+
+EFI and EDK2 support:
+    Enabled /WX flag for MSVC builds
+    Added support for AcpiOsStall, AcpiOsSleep, and AcpiOsGetTimer
+    Added local support for 64-bit multiply and shift operations
+    Added support to compile acpidump.efi on Windows
+    Added OSL function stubs for interfaces not used under EFI
+
+Added additional support for the _DMA predefined name. _DMA returns a 
+buffer containing a resource template. This change add support within the 
+resource manager (AcpiWalkResourceBuffer) to walk and parse this list of 
+resource descriptors. Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Fixed a problem where the internal input line buffer(s) could 
+overflow if there are very long lines in the input ASL source code file. 
+Implemented buffer management that automatically increases the size of 
+the buffers as necessary.
+
+iASL: Added an option (-vx) to "expect" particular remarks, warnings and 
+errors. If the specified exception is not raised during compilation, the 
+compiler emits an error. This is intended to support the ASL test suite, 
+but may be useful in other contexts.
+
+iASL: Implemented a new predefined macro, __METHOD__, which returns a 
+string containing the name of the current control method that is being 
+compiled.
+
+iASL: Implemented debugger and table compiler support for the SDEI ACPI 
+table (Software Delegated Exception Interface). James Morse 
+<james.morse@arm.com>
+
+Unix/Linux makefiles: Added an option to disable compile optimizations. 
+The disable occurs when the NOOPT flag is set to TRUE. 
+theracermaster@gmail.com
+
+Acpidump: Added support for multiple DSDT and FACS tables. This can occur 
+when there are different tables for 32-bit versus 64-bit.
+
+Enhanced error reporting for the ASL test suite (ASLTS) by removing 
+unnecessary/verbose text, and emit the actual line number where an error 
+has occurred. These changes are intended to improve the usefulness of the 
+test suite.
