Subject: mtr v0.35
X-Git-Tag: v0.35^0
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=efb19614783cab6161dc791b4bf550193236fd51;p=thirdparty%2Fmtr.git

mtr v0.35

 - Added Craig Milo Rogers pause/resume for GTK patch.
 - Added Craig Milo Rogers cleanup of "reset". (restart at the
   beginning)
 - Net_open used to send a first packet. After that the display-driver
   got a chance to distort the timing by taking its time to
   initialize.
