+15 November 2013. Summary of changes for version 20131115:
+
+This release is available at https://acpica.org/downloads
+
+
+1) ACPICA kernel-resident subsystem:
+
+Resource Manager: Fixed loop termination for the "get AML length" 
+function. The loop previously had an error termination on a NULL resource 
+pointer, which can never happen since the loop simply increments a valid 
+resource pointer. This fix changes the loop to terminate with an error on 
+an invalid end-of-buffer condition. The problem can be seen as an 
+infinite loop by callers to AcpiSetCurrentResources with an invalid or 
+corrupted resource descriptor, or a resource descriptor that is missing 
+an END_TAG descriptor. Reported by Dan Carpenter 
+<dan.carpenter@oracle.com>. Lv Zheng, Bob Moore.
+
+Table unload and ACPICA termination: Delete all attached data objects 
+during namespace node deletion. This fix updates namespace node deletion 
+to delete the entire list of attached objects (attached via 
+AcpiAttachObject) instead of just one of the attached items. ACPICA BZ 
+1024. Tomasz Nowicki (tomasz.nowicki@linaro.org).
+
+ACPICA termination: Added support to delete all objects attached to the 
+root namespace node. This fix deletes any and all objects that have been 
+attached to the root node via AcpiAttachData. Previously, none of these 
+objects were deleted. Reported by Tomasz Nowicki. ACPICA BZ 1026.
+
+Debug output: Do not emit the function nesting level for the in-kernel 
+build. The nesting level is really only useful during a single-thread 
+execution. Therefore, only enable this output for the AcpiExec utility. 
+Also, only emit the thread ID when executing under AcpiExec (Context 
+switches are still always detected and a message is emitted). ACPICA BZ 
+972.
+
+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:  95.9K Code, 27.0K Data, 122.9K Total
+    Debug Version:     185.1K Code, 77.2K Data, 262.3K Total

+    Non-Debug Version:  95.8K Code, 27.0K Data, 122.8K Total
+    Debug Version:     185.2K Code, 77.2K Data, 262.4K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+AcpiExec/Unix-OSL: Use <termios.h> instead of <termio.h>. This is the 
+correct portable POSIX header for terminal control functions.
+
+Disassembler: Fixed control method invocation issues related to the use 
+of the CondRefOf() operator. The problem is seen in the disassembly where 
+control method invocations may not be disassembled properly if the 
+control method name has been used previously as an argument to CondRefOf. 
+The solution is to not attempt to emit an external declaration for the 
+CondRefOf target (it is not necessary in the first place). This prevents 
+disassembler object type confusion. ACPICA BZ 988.
+
+Unix Makefiles: Added an option to disable compiler optimizations and the 
+_FORTIFY_SOURCE flag. Some older compilers have problems compiling ACPICA 
+with optimizations (reportedly, gcc 4.4 for example). This change adds a 
+command line option for make (NOOPT) that disables all compiler 
+optimizations and the _FORTIFY_SOURCE compiler flag. The default 
+optimization is -O2 with the _FORTIFY_SOURCE flag specified. ACPICA BZ 
+1034. Lv Zheng, Bob Moore.
+
+Tests/ASLTS: Added options to specify individual test cases and modes. 
+This allows testers running aslts.sh to optionally specify individual 
+test modes and test cases. Also added an option to disable the forced 
+generation of the ACPICA tools from source if desired. Lv Zheng.
