+10 August 2018. Summary of changes for version 20180810:
+
+
+1) ACPICA kernel-resident subsystem:
+
+Initial ACPI table loading: Attempt to continue loading ACPI tables 
+regardless of malformed AML. Since migrating table initialization to the 
+new module-level code support, the AML interpreter rejected tables upon 
+any ACPI error encountered during table load. This is a problem because 
+non-serious ACPI errors during table load do not necessarily mean that 
+the entire definition block (DSDT or SSDT) is invalid. This change 
+improves the table loading by ignoring some types of errors that can be 
+generated by incorrect AML. This can range from object type errors, scope 
+errors, and index errors.
+
+Suspend/Resume support: Update to stop unconditionally clearing ACPI IRQs 
+during suspend/resume. The status of ACPI events is no longer cleared 
+when entering the ACPI S5 system state (power off) which caused some 
+systems to power up immediately after turning off power in certain 
+situations. This was a functional regression. It was fixed by clearing 
+the status of all ACPI events again when entering S5 (for system-wide 
+suspend or hibernation the clearing of the status of all events is not 
+desirable, as it might cause the kernel to miss wakeup events sometimes). 
+Rafael Wysocki.
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+AcpiExec: Enhanced the -fi option (Namespace initialization file). Field 
+elements listed in the initialization file were previously initialized 
+after the table load and before executing module-level code blocks. 
+Recent changes in the module-level code support means that the table load 
+becomes a large control method execution. If fields are used within 
+module-level code and we are executing with the -fi option, the 
+initialization values were used to initialize the namespace object(s) 
+only after the table was finished loading. This change Provides an early 
+initialization of objects specified in the initialization file so that 
+field unit values are populated during the table load (not after the 
+load).
+
+AcpiExec: Fixed a small memory leak regression that could result in 
+warnings during exit of the utility. These warnings were similar to 
+these:
+    0002D690 Length 0x0006 nsnames-0502 [Not a Descriptor - too small]
+    0002CD70 Length 0x002C utcache-0453 [Operand] Integer RefCount 0x0001
