+----------------------------------------
+16 August 2019. Summary of changes for version 20190816:
+
+This release is available at https://acpica.org/downloads
+
+
+1) ACPICA kernel-resident subsystem:
+
+Modified the OwnerId mechanism to allow for more Owner Ids. The previous 
+limit was 256 Ids, now it is 4096 Ids. This prevents OWNER_ID_LIMIT 
+exceptions on machines with a large number of initialization threads, 
+many CPU cores and nested initialization control methods.
+
+Introduced acpi_dispatch_gpe() as a wrapper around AcpiEvDetectGpe() for 
+checking if the given GPE (as represented by a GPE device handle and a 
+GPE number) is currently active and dispatching it (if that's the case) 
+outside of interrupt context.
+
+Table load: exit the interpreter before initializing objects within the 
+new table This prevents re-acquiring the interpreter lock when loading 
+tables
+
+Added the "Windows 2019" string to the _OSI support (version 1903). Jung-
+uk Kim
+
+Macros: removed pointer math on a null pointer. Causes warnings on some 
+compilers and/or tools. Changed ACPI_TO_POINTER to use ACPI_CAST_PTR 
+instead of using arithmetic.
+
+Fully deployed the ACPI_PRINTF_LIKE macro. This macro was not being used 
+across all "printf-like" internal functions. Also, cleanup all calls to 
+such functions (both in 32-bit mode and 64-bit mode) now that they are 
+analyzed by the gcc compiler via ACPI_PRINTF_LIKE.
+
+
+2) iASL Compiler/Disassembler and ACPICA tools:
+
+iASL: implemented a new data table compiler flex/bison front-end. This 
+change is internal and is not intended to result in changes to the 
+compiled code. This new compiler front-end can be invoked using the -tp 
+option for now, until the old mechanism is removed.
+
+ASLTS: Implemented a new data table compiler test suite. This test suite 
+generates all table templates and compile/disassemble/re-compile/binary-
+compare each file. 
+
+iASL: return -1 if AML files were not generated due to compiler errors
+
+iASL: added a warning on use of the now-legacy ASL Processor () keyword.
+
+iASL: added an error on _UID object declaration that returns a String 
+within a Processor () declaration. A _UID for a processor must be an 
+Integer.
+
+iASL: added a null terminator to name strings that consist only of 
+multiple parent prefixes (^)
+
+iASL: added support to compile both ASL and data table files in a single 
+command.
+
+Updated the tool generation project files that were recently migrated to 
+MSVC 2017 to eliminate all new warnings. The new project files appear in 
+the directory \acpica\generate\msvc2017. This change effectively 
+deprecates the older project files in \acpica\generate\msvc9.
+
+
+----------------------------------------
+03 July 2019. Summary of changes for version 20190703:
+
+
+1) ACPICA kernel-resident subsystem:
+
+Remove legacy module-level support code. There were still some remnants 
+of the legacy module-level code executions. Since we no longer support 
+this option, this is essentially dead code and has been removed from the 
+ACPICA source.
+
+iASL: ensure that _WAK, _PTS, _TTS, and _Sx are declared only at the root 
+scope. If these named objects are declared outside the root scope, they 
+will not be invoked by any host Operating System.
+
+Clear status of GPEs on first direct enable. ACPI GPEs (other than the EC 
+one) can be enabled in two situations. First, the GPEs with existing _Lxx 
+and _Exx methods are enabled implicitly by ACPICA during system 
+initialization.  Second, the GPEs without these methods (like GPEs listed 
+by _PRW objects for wakeup devices) need to be enabled directly by the 
+code that is going to use them (e.g. ACPI power management or device 
+drivers).
+
+In the former case, if the status of a given GPE is set to start with, 
+its handler method (either _Lxx or _Exx) needs to be invoked to take care 
+of the events (possibly) signaled before the GPE was enabled. In the 
+latter case, however, the first caller of AcpiEnableGpe() for a given GPE 
+should not be expected to care about any events that might be signaled 
+through it earlier.  In that case, it is better to clear the status of 
+the GPE before enabling it, to prevent stale events from triggering 
+unwanted actions (like spurious system resume, for example).
+
+For this reason, modify AcpiEvAddGpeReference() to take an additional 
+boolean argument indicating whether or not the GPE status needs to be 
+cleared when its reference counter changes from zero to one and make 
+AcpiEnableGpe() pass TRUE to it through that new argument.
+
+
+2) iASL Compiler/Disassembler and ACPICA tools:
+
+The tool generation process has been migrated to MSVC 2017, and all 
+project files have been upgraded. The new project files appear in the 
+directory \acpica\generate\msvc2017. This change effectively deprecates 
+the older project files in \acpica\generate\msvc9.
+
+iASL: ensure that _WAK, _PTS, _TTS, and _Sx are declared only at the root 
+scope. If these named objects are declared outside the root scope, they 
+will not be invoked by any host Operating System
+
+----------------------------------------
+09 May 2019. Summary of changes for version 20190509:
+
+
+1) ACPICA kernel-resident subsystem:
+
+Revert commit  6c43e1a ("ACPICA: Clear status of GPEs before enabling 
+them") that causes problems with Thunderbolt controllers to occur if a 
+dock device is connected at init time (the xhci_hcd and thunderbolt 
+modules crash which prevents peripherals connected through them from 
+working). Commit 6c43e1a effectively causes commit ecc1165b8b74 ("ACPICA: 
+Dispatch active GPEs at init time") to get undone, so the problem 
+addressed by commit ecc1165b8b74 appears again as a result of it.
+
+
+2) iASL Compiler/Disassembler and ACPICA tools:
+
+Reverted iASL: Additional forward reference detection. This change 
+reverts forward reference detection for field declarations. The feature 
+unintentionally emitted AML bytecode with incorrect package lengths for 
+some ASL code related to Fields and OperationRegions. This malformed AML 
+can cause systems to crash
+during boot. The malformed AML bytecode is emitted in iASL version 
+20190329 and 20190405.
+
+iASL: improve forward reference detection. This change improves forward 
+reference detection for named objects inside of scopes. If a parse object 
+has the OP_NOT_FOUND_DURING_LOAD set, it means that Op is a reference to 
+a named object that is declared later in the AML bytecode. This is 
+allowed if the reference is inside of a method and the declaration is 
+outside of a method like so:
+
+DefinitionBlock(...)
+{
+    Method (TEST)
+    {
+        Return (NUM0)
+    }
+    Name (NUM0,0)
+}
+
+However, if the declaration and reference are both in the same method or 
+outside any methods, this is a forward reference and should be marked as 
+an error because it would result in runtime errors.
+
+DefinitionBlock(...)
+{
+    Name (BUFF, Buffer (NUM0) {}) // Forward reference
+    Name (NUM0, 0x0)
+
+    Method (TEST)
+    {
+        Local0 = NUM1
+        Name (NUM1, 0x1) // Forward reference
+        return (Local0)
+    }
+}
+
+iASL: Implemented additional buffer overflow analysis for BufferField 
+declarations. Check if a buffer index argument to a create buffer field 
+operation is beyond the end of the target buffer.
+
+This affects these AML operators:
+ 
+   AML_CREATE_FIELD_OP
+   AML_CREATE_BIT_FIELD_OP
+   AML_CREATE_BYTE_FIELD_OP
+   AML_CREATE_WORD_FIELD_OP
+   AML_CREATE_DWORD_FIELD_OP
+   AML_CREATE_QWORD_FIELD_OP
+
+ There are three conditions that must be satisfied in order to allow this 
+validation at compile time:
+ 
+   1) The length of the target buffer must be an integer constant
+   2) The index specified in the create* must be an integer constant
+   3) For CreateField, the bit length argument must be non-zero.
+
+Example:
+    Name (BUF1, Buffer() {1,2})
+    CreateField (BUF1, 7, 9, CF03)  // 3: ERR
+
+dsdt.asl     14:     CreateField (BUF1, 7, 9, CF03)  // 3: ERR
+Error    6165 -                           ^ Buffer index beyond end of 
+target buffer
