Revision 0eb4f7cdf85273c88feb95c677a808cee9cfd859 authored by J. Bruce Fields on 05 August 2007, 21:18:52 UTC, committed by J. Bruce Fields on 05 August 2007, 21:29:01 UTC
Update documentation to reflect the --track default. That change seems to have happened in the 1.5.3 -rc's, so bump the "for version x.y.z or newer" warning as well. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
