+15 February 2012. Summary of changes for version 20120215:
+
+This release is available at www.acpica.org/downloads.
+The ACPI 5.0 specification is available at www.acpi.info.
+
+1) ACPICA Core Subsystem:
+
+There have been some major changes to the sleep/wake support code, as 
+described below (a - e).
+
+a) The AcpiLeaveSleepState has been split into two interfaces, similar to 
+AcpiEnterSleepStatePrep and AcpiEnterSleepState. The new interface is 
+AcpiLeaveSleepStatePrep. This allows the host to perform actions between the 
+time the _BFS method is called and the _WAK method is called. NOTE: all hosts 
+must update their wake/resume code or else sleep/wake will not work properly. 
+Rafael Wysocki.
+
+b) In AcpiLeaveSleepState, now enable all runtime GPEs before calling the _WAK 
+method. Some machines require that the GPEs are enabled before the _WAK method 
+is executed. Thomas Renninger.
+
+c) In AcpiLeaveSleepState, now always clear the WAK_STS (wake status) bit. 
+Some BIOS code assumes that WAK_STS will be cleared on resume and use it to 
+determine whether the system is rebooting or resuming. Matthew Garrett.
+
+d) Move the invocations of _GTS (Going To Sleep) and _BFS (Back From Sleep) to 
+match the ACPI specification requirement. Rafael Wysocki.
+
+e) Implemented full support for the ACPI 5.0 SleepStatus and SleepControl 
+registers within the V5 FADT. This support adds two new files: 
+hardware/hwesleep.c implements the support for the new registers. Moved all 
+sleep/wake external interfaces to hardware/hwxfsleep.c.
+
+
+Added a new OSL interface for ACPI table overrides, 
+AcpiOsPhysicalTableOverride. This interface allows the host to override a 
+table via a physical address, instead of the logical address required by 
+AcpiOsTableOverride. This simplifies the host implementation. Initial 
+implementation by Thomas Renninger. The ACPICA implementation creates a single 
+shared function for table overrides that attempts both a logical and a 
+physical override.
+
+Expanded the OSL memory read/write interfaces to 64-bit data 
+(AcpiOsReadMemory, AcpiOsWriteMemory.) This enables full 64-bit memory 
+transfer support for GAS register structures passed to AcpiRead and AcpiWrite.
+
+Implemented the ACPI_REDUCED_HARDWARE option to allow the creation of a custom 
+build of ACPICA that supports only the ACPI 5.0 reduced hardware (SoC) model. 
+See the ACPICA reference for details. ACPICA BZ 942. This option removes about 
+10% of the code and 5% of the static data, and the following hardware ACPI 
+features become unavailable:
+    PM Event and Control registers
+    SCI interrupt (and handler)
+    Fixed Events
+    General Purpose Events (GPEs)
+    Global Lock
+    ACPI PM timer
+    FACS table (Waking vectors and Global Lock)
+
+Updated the unix tarball directory structure to match the ACPICA git source 
+tree. This ensures that the generic unix makefiles work properly (in 
+generate/unix).  Also updated the Linux makefiles to match. ACPICA BZ 867.
+
+Updated the return value of the _REV predefined method to integer value 5 to 
+reflect ACPI 5.0 support.
+
+Moved the external ACPI PM timer interface prototypes to the public acpixf.h 
+file where they belong.
+
+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:  92.8K Code, 24.9K Data, 117.7K Total
+    Debug Version:     171.7K Code, 72.9K Data, 244.5K Total
+  Current Release:
+    Non-Debug Version:  93.0K Code, 25.0K Data, 118.0K Total
+    Debug Version:     172.5K Code, 73.2K Data, 245.7K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Disassembler: Fixed a problem with the new ACPI 5.0 serial resource 
+descriptors (I2C, SPI, UART) where the resource produce/consumer bit was 
+incorrectly displayed.
+
+AcpiHelp: Add display of ACPI/PNP device IDs that are defined in the ACPI 
+specification.

+# ACPICA package generation script for Cygwin/Windows execution
+#
+# Requires cygwin be installed - http://www.cygwin.com
+# and its /bin be *first* in your path.
+#
+# Windows packages require pkzip25 (free, and is available from numerous
+# sources - search for "pkzip25" or "pkzip25.exe")
+#
+# Execute this script from the acpica/generate/release directory.
+#
+# Constructed packages are placed in the acpica/generate/release/current
+# directory.
+#
+# Line Terminators: Windows source packages leave the CR/LF terminator.
+# Unix packages convert the CR/LF terminators to LF only.
+#
+# Usage:
+#
+#   build <package_type> <target_type>
+#
+#   where:
+#       <package_type> is one of:
+#           source  - Build an ACPICA source package (core and all tools)
+#           test    - Build an ACPICA test suite package
+#           binary  - Build an ACPICA binary tools package
+#
+#       <target_type> is one of:
+#           win     - Generate Windows package (Intel license, CRLF line terminators)
+#           unix    - Generate Unix package (Intel license, LF line terminators)
