+2010-07-08 Jon Dugan <jdugan@x1024.net>

+
+2010-04-10 Jon Dugan <jdugan@x1024.net>
+
+* update autoconf goo using Autoconf 2.65, this should help portability a bit

+* tracker issue 2836973

+2010-03-31 Gerrit Renker <grenker@users.sourceforge.net>

+* tracker issue 2006708
+
+2010-03-31 Gerrit Renker <grenker@users.sourceforge.net>
+
+* "neater" output for some units, eg Kbps, Mbps, Gbps
+* addresses some typos
+
+2008-05-09 Gerrit Renker <grenker@users.sourceforge.net>
+
+* replace costly gettimeofday() with nanonsleep() See:

+
+2008-05-09 Jon Dugan <jdugan@x1024.net>
+
+* change currLen to unsigned to squelch warning generated by Nathan's patch
+
+2008-05-09 Nathan Jones <nmjones@users.sourceforge.net>
+
+* prevent underflow when the amount of data to be transmitted (-n) is not a
+multiple of the buffer size (-l)  Patch:
+https://sourceforge.net/tracker/index.php?func=detail&aid=1943432&group_id=128336&atid=711373
+
+2008-04-08 Jon Dugan <jdugan@x1024.net>
+
+* print report headers only once
+* use appropriate report header for UDP tests
+
+2008-04-07 Jon Dugan <jdugan@x1024.net>
+
+* Add man page to autoconf goo
+* Bump the version in autoconf
+* Add missing LICENSE file
+
+2008-04-04 Jon Dugan <jdugan@x1024.net>
+
+* Incorporate help string fixes from Claus Klein
+* Incorporate patch to restore header line in stats output from Claus Klein
+* Reworked help string code to remove redundancy
+* Add initial man page
+
+2008-03-19 Stephen Hemminger <shemminger@linux-foundation.org>
+
+* Add new option to allow selecting the sender congestion control
+algorithm. This is a Linux specific extension useful for testing
+other congestion control algorithms.
+
+2008-03-19 Stephen Hemminger <shemminger@linux-foundation.org>
+
+* Use sched_yield rather than usleep(0) as it behaves better on Linux
+
+2008-03-12 Jon Dugan <jdugan@x1024.net>
+
+* Rework Client::RunTCP so to update the stats for every packet if -i is set.
+If -i is not set then the stats are only updated at the end of the run. This
+was fallout of Andrew's patch.
+
+* Added -Wall to CXXFLAGS and CFLAGS.  This generated a lot of noise in the
+autotools generated files.
+
+* Added initial AUTHORS file.  This is incomplete, but it's a start.
+
+2008-03-12 Andrew Gallatin <gallatin@gmail.com>
+
+* Rework threading.  This is done by having a condition variable for the reporting
+thread rather than using sched_yield and/or usleep.  
+
+* Address performance issues on non Linux systems by avoiding system calls
+which are expensive on platforms other than Linux.
+
+* Fixes from FreeBSD ports: max_size_t is now 64 bits and not Iperf does not
+exit on ENOBUFS.
+
+2007-10-01 JSE <jestabro@ncsa.uiuc.edu>
+
+* ChangeLog file added
+
+2007-10-05 JSE <jestabro@ncsa.uiuc.edu>
+
+* Thread.c (thread_stop): "pthread_cancel (oldTID )" should be
+"pthread_cancel (thread->mTID)"
