Re: Processing older versions (topic split from v6 Upgrade)


For what it is worth I believe " the forced upgrade path that all the
commercial vendors use" is a commercial decision to force new license sales
and/or give value to maintenance contracts. This has a negative impact on
users with older versions who are forced to upgrade, which costs them money.

I don't think it is as much of an issue for Kicad users because the software
is free.

It doesn't.  And it can't between major releases (e.g. 4-5, 5-6)

I don't anticipate anyone wanting to support this kind of behavior in KiCad.
Altium has separate departments for developers and technical support.  We

We don't have the person-hours to provide support for multiple versions. 
  We don't force people to upgrade but we also don't have enough time in the
day to deal with the extra problems that come from the kind of teamwork you
are describing.
