 ----------------------------------------
+29 July 2016. Summary of changes for version 20160729:
+
+This release is available at https://acpica.org/downloads
+
+
+1) ACPICA kernel-resident subsystem:
+
+Implemented basic UEFI support for the various ACPICA tools. This 
+includes:
+1) An OSL to implement the various AcpiOs* interfaces on UEFI.
+2) Support to obtain the ACPI tables on UEFI.
+3) Local implementation of required C library functions not available on 
+UEFI.
+4) A front-end (main) function for the tools for UEFI-related 
+initialization.
+
+The initial deployment of this support is the AcpiDump utility executing 
+as an UEFI application via EDK2 (EDKII, "UEFI Firmware Development Kit"). 
+Current environments supported are Linux/Unix. MSVC generation is not 
+supported at this time. See the generate/efi/README file for build 
+instructions. Lv Zheng.
+
+Future plans include porting the AcpiExec utility to execute natively on 
+the platform with I/O and memory access. This will allow viewing/dump of 
+the platform namespace and native execution of ACPI control methods that 
+access the actual hardware. To fully implement this support, the OSL 
+functions below must be implemented with UEFI interfaces. Any community 
+help in the implementation of these functions would be appreciated:
+    AcpiOsReadPort
+    AcpiOsWritePort
+    AcpiOsReadMemory
+    AcpiOsWriteMemory
+    AcpiOsReadPciConfiguration
+    AcpiOsWritePciConfiguration
+
+
+Restructured and standardized the C library configuration for ACPICA, 
+resulting in the various configuration options below. This includes a 
+global restructuring of the compiler-dependent and platform-dependent 
+include files. These changes may affect the existing platform-dependent 
+configuration files on some hosts. Lv Zheng. 
+
+The current C library configuration options appear below. For any issues, 
+it may be helpful to examine the existing compiler-dependent and 
+platform-dependent files as examples. Lv Zheng. 
+
+1) Linux kernel:
+    ACPI_USE_STANDARD_HEADERS=n in order not to use system-provided C 
+library.
+    ACPI_USE_SYSTEM_CLIBRARY=y in order not to use ACPICA mini C library.
+2) Unix/Windows/BSD applications:
+    ACPI_USE_STANDARD_HEADERS=y in order to use system-provided C 
+library.
+    ACPI_USE_SYSTEM_CLIBRARY=y in order not to use ACPICA mini C library.
+3) UEFI applications:
+    ACPI_USE_STANDARD_HEADERS=n in order not to use system-provided C 
+library.
+    ACPI_USE_SYSTEM_CLIBRARY=n in order to use ACPICA mini C library.
+4) UEFI applications (EDK2/StdLib):
+    ACPI_USE_STANDARD_HEADERS=y in order to use EDK2 StdLib C library.
+    ACPI_USE_SYSTEM_CLIBRARY=y in order to use EDK2 StdLib C library.
+
+
+AML interpreter: "module-level code" support. Allows for execution of so-
+called "executable" AML code (math/logical operations, etc.) outside of 
+control methods not just at the module level (top level) but also within 
+any scope declared outside of a control method - Scope{}, Device{}, 
+Processor{}, PowerResource{}, and ThermalZone{}. Lv Zheng. 
+
+Simplified the configuration of the "maximum AML loops" global option by 
+adding a global public variable, "AcpiGbl_MaxLoopIterations" which can be 
+modified at runtime.
+
+
+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.
+
+  Current Release:
+    Non-Debug Version: 139.1K Code, 22.9K Data, 162.0K Total
+    Debug Version:     199.0K Code, 81.8K Data, 280.8K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Add full support for the RASF ACPI table (RAS Features Table). 
+Includes disassembler, data table compiler, and header support.
+
+iASL Expand "module-level code" support. Allows for 
+compilation/disassembly of so-called "executable" AML code (math/logical 
+operations, etc.) outside of control methods not just at the module level 
+(top level) but also within any scope declared outside of a control 
+method - Scope{}, Device{}, Processor{}, PowerResource{}, and 
+ThermalZone{}.
+
+AcpiDump: Added support for dumping all SSDTs on newer versions of 
+Windows. These tables are now easily available -- SSDTs are not available 
+through the registry on older versions.
