I've done the backout and will submit Peter's change for MT5 on the 4th. I'll do the ifi_unused => ifi_epoch change soon, but I need to verify my theory that I can use a time_t without changing the struct size. > > - After 5.3 is released, declare that upgrades to 6.0 from releases > > other then 4.x (x>=11) and 5.y (y>=3) require special handling > > and allow if_data to grow as demand requires. > > - If additional precision is deemed necessary at some future date, > > add a second ifi_epoch_tv. > > We do not have to come to an agreement on these steps until we are > ready to make additional changes to the structure.

I think it would be useful to declare upfront that should a change be made, we are willing to jetison full, offical support for upgrades to 6.0 from 5.x (x<3), but that's a minor detail. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
