by hand
* XDDCP names timestamps consistently for all verbosity levels
xdd-7.0.0 RC21
==============
* XDD now provides its own utilties for resolving IPs, truncating files, and
determining file size

* XDDCP: Change direct I/O and ordering options so that they can
can be specified on source, destination, or both. The way
to invoke is xddcp -d s|d|b, where s enables source DIO,
d enabled destination DIO, and b enables DIO on both ends.
Alternative spellings are also enabled: source, dest, both,
and sd can also be used to specify the relevant ends to
configure.
* XDDCP: Add option for creating time series graph of transfer (-w)
* XDDCP: Add option that will allow a number of automatic retries (-n). If
you use this, you probably want to also use -a and -f. And while
I am presently allowing this option to work with multi-file transfers
I do not believe that it will work all that well for that case.

* XDDFT: XDD forkthread supports options now.
* XDDFT: XDD forkthread installs with rest of XDD.
xdd-7.0.0 RC15
==============
* XDD: Supports serial ordered thread scheduling
* XDD: Default mode is now loosely ordered thread scheduling

* XDDCP: Truncates file to correct length
* XDDCP: Checks versions of xdd.Linux on both ends
* XDDCP: More robust error messages

* XDDCP: Detect if the destination side ports are already in use.
* XDDCP: Disallow -dio when using devices -- it won't work anyway
* XDDCP: Changing request size back to 16MiB
* XDDCP: Increasing default thread count to 12.
* XDDMCP: Adding initial hard-coded test script.

* XDD: Add AIX support
* XDDCP: Proper support for SIGINT, SIGQUIT, and SIGTERM (i.e. Ctrl-C support)
xdd-7.0.0 RC11
=============
* XDDCP: Destination logs are written to the home dir if permissions don't
exist to write log to destination dir. If home dir permissions
don't exist, an error is triggered.
* XDDCP: Source logs are written to stdout if permissions don't exist
to write log to the local directory. A warning message diagnostic
is printed in this case.
xdd-7.0.0 RC10
=============

* XDDCP: Added a -a option to automate the restart/resume process for user
* XDDCP: Added -p portnum option to script
* XDDCP: Remove option that appeared to allow partial file transfers. It
didn't do exactly what it said it did, and positional parameters are error prone.
* XDDCP: Explictly documented the host:<path_to_file> format of input. Its supported,
if it doesn't work for you, file a bug and we'll fix it.
* XDDCP: Tried to fix trailing message in script (still says
"Transfer finished." when the user explicitly cancels xdd with Ctrl-c.
* XDDCP: Added -F option that allows user to specify transfer files inside
of the source side file.
xdd-7.0.0 RC8
=============
* -createnewfiles patched to correctly create file sizes over multiple passes
* -dio works on destination side of e2e transfers of files of odd sizes
* fastinstall makefile target added
xdd-7.0.0 RC7
=============
* ChangeLog file added for changelog information.
* HOWTO file added describing how a release is cut.
* xddcp script updated to work with -e2e style options and fix mis-quote
in supplied script that launched remote command without focus.
* Add -bytes option to specify any file size for transfer.
* Transfer files of arbitrary sizes without DIO. NOTE: When DIO is
enabled, the amount of data to be transferred must be divisible by 4096.
* Fix option handling in xddcp to work correctly and add -s option for DIO
on the source side.
* Fix bug in xddcp script so that remote side works a bit (still not fully
guaranteed to work -- the script kills itself, so xdd processes may still
exist on remote side).
* Include contrib/TEST_xdd_copy.sh, a copy test driver that generates the
the source, removes existing destination files, and computes the md5sum
of the resulting files for comparison after transfer.
* Including testing results in tests/output/rc7 subdirectory.
xdd-7.0.0 RC6
=============
* Randomized reads now work with random offsets.
* xdd_forkthread.sh script included to demonstrate forkthread behavior.
