+18 October 2019. Summary of changes for version 20191018:
+
+
+1) ACPICA kernel-resident subsystem:
+
+Debugger: added a new command: ?Fields [address space ID]?. This command 
+dumps the contents of all field units that are defined within the 
+namespace with a particular address space ID.
+
+Modified the external interface AcpiLoadTable() to return a table index. 
+This table index can be used for unloading a table for debugging.
+    ACPI_STATUS
+    AcpiLoadTable (
+        ACPI_TABLE_HEADER       *Table,
+        UINT32                  *TableIndex))
+
+Implemented a new external interface: AcpiUnloadTable() This new function 
+takes a table index as an argument and unloads the table. Useful for 
+debugging only.
+    ACPI_STATUS
+    AcpiUnloadTable (
+        UINT32                  TableIndex))
+
+Ported the AcpiNames utility to use the new table initialization 
+sequence. The utility was broken before this change. Also, it was 
+required to include most of the AML interpreter into the utility in order 
+to process table initialization (module-level code execution.)
+
+Update for results from running Clang V8.0.1. This fixes all "dead 
+assignment" warnings. There are still several "Dereference of NULL 
+pointer" warnings, but these have been found to be false positive 
+warnings.
+
+
+2) iASL Compiler/Disassembler and ACPICA tools:
+
+iASL: numerous table compiler changes to ensure that the usage of 
+yacc/bison syntax is POSIX-compliant.
+
+iASL/disassembler: several simple bug fixes in the data table 
+disassembler.
+
+Acpiexec: expanded the initialization file (the -fi option) to initialize 
+strings, buffers, packages, and field units.
