+15 February 2019. Summary of changes for version 20190215:
 
 This release is available at https://acpica.org/downloads
 
 
+0) Support for ACPI specification version 6.3:
+
+Add PCC operation region support for the AML interpreter. This adds PCC 
+operation region support in the AML interpreter and a default handler for 
+acpiexec. The change also renames the PCC region address space keyword to 
+PlatformCommChannel.
+
+Support for new predefined methods _NBS, _NCH, _NIC, _NIH, and _NIG. 
+These methods provide OSPM with health information and device boot 
+status.
+
+PDTT: Add TriggerOrder to the PCC Identifier structure. The field value 
+defines if the trigger needs to be invoked by OSPM before or at the end 
+of kernel crash dump processing/handling operation.
+
+SRAT: Add Generic Affinity Structure subtable. This subtable in the SRAT 
+is used for describing devices such as heterogeneous processors, 
+accelerators, GPUs, and IO devices with integrated compute or DMA 
+engines.
+
+MADT: Add support for statistical profiling in GICC. Statistical 
+profiling extension (SPE) is an architecture-specific feature for ARM.
+
+MADT: Add online capable flag. If this bit is set, system hardware 
+supports enabling this processor during OS runtime.
+
+New Error Disconnect Recover Notification value. There are a number of 
+scenarios where system Firmware in collaboration with hardware may 
+disconnect one or more devices from the rest of the system for purposes 
+of error containment. Firmware can use this new notification value to 
+alert OSPM of such a removal.
+
+PPTT: New additional fields in Processor Structure Flags. These flags 
+provide more information about processor topology.
+
+NFIT/Disassembler: Change a field name from "Address Range" to "Region 
+Type".
+
+HMAT updates: make several existing fields to be reserved as well as 
+rename subtable 0 to "memory proximity domain attributes".
+
+GTDT: Add support for new GTDT Revision 3. This revision adds information 
+for the EL2 timer.
+
+iASL: Update the HMAT example template for new fields.
+
+iASL: Add support for the new revision of the GTDT (Rev 3).
+
+
 1) ACPICA kernel-resident subsystem:
 
+AML Parser: fix the main AML parse loop to correctly skip erroneous 
+extended opcodes. AML opcodes come in two lengths: 1-byte opcodes and 2-
+byte extended opcodes. If an error occurs during an AML table load, the 
+AML parser will continue loading the table by skipping the offending 
+opcode. This implements a "load table at any cost" philosophy.
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL: Add checks for illegal object references, such as a reference 
+outside of method to an object within a method. Such an object is only 
+temporary.
+
+iASL: Emit error for creation of a zero-length operation region. Such a 
+region is rather pointless. If encountered, a runtime error is also 
+implemented in the interpeter.
+
+Debugger: Fix a possible fault with the "test objects" command.
+
+iASL: Makefile: support parent directory filenames containing embedded 
+spaces.
+
+iASL: Update the TPM2 template to revision 4.
+
+iASL: Add the ability to report specific warnings or remarks as errors.
+
+Disassembler: Disassemble OEMx tables as actual AML byte code. 
+Previously, these tables were treated as "unknown table".
+
+iASL: Add definition and disassembly for TPM2 revision 3.
+
+iASL: Add support for TPM2 rev 3 compilation.
