I.	Overview

This document describes the changes between versions 8.01.07
and 8.01.12 of the QLogic QLdirect driver.


II.	Enhancements 
		
-   Make cosmetic changes to readme.txt to bring
    file in line with new consistency standards.
-   Make the optimized IO timeout detection mechanism
    so that it must be explicitly turned on with the
    0x02 bit in the Optimization registry parameter.
    The default is to use the standard timeout check.
-   Add support for getting and setting the path
    information by port name as well as by node name.
    This is necessary to allow the applications to
    fully support non-SPIFFI devices.
-   Add support for running with IntFiltr interrupt
    affinity filter driver.
-   Change maximum adapters again from 16 to 64.
-   Add optimized IO timeout detection mechanism
    when running without multipath enabled.
-   Add support for TimerCpuNumber registry
    parameter to move timer overhead.
-   Reduce volume of debug text output when dumping
    device data structures.
-   Fix 64-bit installation to explicitly check for
    old driver file and remove it.
-   Add support for DisableAutoFailback registry
    parameter.
-   Add support for "get addresses" IOCTL interface
    for memory optimization testing. 
-   Add optimizations including removing a redundant
    spinlock, and making the PerCpuData more NUMA-
    memory-aware for allocating memory.


III.	Bug Fixes

-   Fix potential blue screen; add checking for NULL
    buffer passed into IOCTL dispatcher.
-   Fix 64-bit installation problems that caused the
    wrong driver file to be installed in the SysWOW64
    directory instead of the System32 directory.


IV.	Known Issues

None


V.      Additional Information

-   QLDirect driver works in conjunction with QLogic SCSI
    miniport drivers only.
