+17 May 2013. Summary of changes for version 20130517:
+
+1) ACPICA kernel-resident subsystem:
 
-This release is available at https://acpica.org/downloads
+Fixed a regression introduced in version 20130328 for _INI methods. This 
+change fixes a problem introduced in 20130328 where _INI methods are no 
+longer executed properly because of a memory block that was not 
+initialized correctly. ACPICA BZ 1016. Tomasz Nowicki 
+<tomasz.nowicki@linaro.org>.
+
+Fixed a possible problem with the new extended sleep registers in the ACPI 
+5.0 FADT. Do not use these registers (even if populated) unless the HW-
+reduced bit is set in the FADT (as per the ACPI specification). ACPICA BZ 
+1020. Lv Zheng.
+
+Implemented return value repair code for _CST predefined objects: Sort the 
+list and detect/remove invalid entries. ACPICA BZ 890. Lv Zheng.
+
+Implemented a debug-only option to disable loading of SSDTs from the 
+RSDT/XSDT during ACPICA initialization. This can be useful for debugging 
+ACPI problems on some machines. Set AcpiGbl_DisableSsdtTableLoad in 
+acglobal.h - ACPICA BZ 1005. Lv Zheng.
+
+Fixed some issues in the ACPICA initialization and termination code: 
+Tomasz Nowicki <tomasz.nowicki@linaro.org>
+1) Clear events initialized flag upon event component termination. ACPICA 
+BZ 1013.
+2) Fixed a possible memory leak in GPE init error path. ACPICA BZ 1018. 
+3) Delete global lock pending lock during termination. ACPICA BZ 1012.
+4) Clear debug buffer global on termination to prevent possible multiple 
+delete. ACPICA BZ 1010.
+
+Standardized all switch() blocks across the entire source base. After many 
+years, different formatting for switch() had crept in. This change makes 
+the formatting of every switch block identical. ACPICA BZ 997. Chao Guan.
+
+Split some files to enhance ACPICA modularity and configurability:
+1) Split buffer dump routines into utilities/utbuffer.c
+2) Split internal error message routines into utilities/uterror.c
+3) Split table print utilities into tables/tbprint.c
+4) Split iASL command-line option processing into asloptions.c
+
+Makefile enhancements:
+1) Support for all new files above.
+2) Abort make on errors from any subcomponent. Chao Guan.
+3) Add build support for Apple Mac OS X. Liang Qi.
+
+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:  96.0K Code, 27.0K Data, 123.0K Total
+    Debug Version:     184.1K Code, 76.8K Data, 260.9K Total
+  Previous Release:
+    Non-Debug Version:  95.6K Code, 26.8K Data, 122.4K Total
+    Debug Version:     183.5K Code, 76.6K Data, 260.1K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+New utility: Implemented an easily portable version of the acpidump 
+utility to extract ACPI tables from the system (or a file) in an ASCII hex 
+dump format. The top-level code implements the various command line 
+options, file I/O, and table dump routines. To port to a new host, only 
+three functions need to be implemented to get tables -- since this 
+functionality is OS-dependent. See the tools/acpidump/apmain.c module and 
+the ACPICA reference for porting instructions. ACPICA BZ 859. Notes:
+1) The Windows version obtains the ACPI tables from the Registry.
+2) The Linux version is under development.
+3) Other hosts - If an OS-dependent module is submitted, it will be 
+distributed with ACPICA.
+
+iASL: Fixed a regression for -D preprocessor option (define symbol). A 
+restructuring/change to the initialization sequence caused this option to 
+no longer work properly.
+
+iASL: Implemented a mechanism to disable specific warnings and remarks. 
+Adds a new command line option, "-vw <messageid> as well as "#pragma 
+disable <messageid>". ACPICA BZ 989. Chao Guan, Bob Moore.
+
+iASL: Fix for too-strict package object validation. The package object 
+validation for return values from the predefined names is a bit too 
+strict, it does not allow names references within the package (which will 
+be resolved at runtime.) These types of references cannot be validated at 
+compile time. This change ignores named references within package objects 
+for names that return or define static packages.
+
+Debugger: Fixed the 80-character command line limitation for the History 
+command. Now allows lines of arbitrary length. ACPICA BZ 1000. Chao Guan.
+
+iASL: Added control method and package support for the -so option 
+(generates AML offset table for BIOS support.)
+
+iASL: issue a remark if a non-serialized method creates named objects. If 
+a thread blocks within the method for any reason, and another thread 
+enters the method, the method will fail because an attempt will be made to 
+create the same (named) object twice. In this case, issue a remark that 
+the method should be marked serialized. NOTE: may become a warning later. 
+ACPICA BZ 909.
