As with all versions of MetaCard, stacks created with earlier version 
can be run in a more recent version.

And as with all versions of MetaCard, an older engine won't be able to 
recognize the format used by a newer engine, since of course the newer 
format didn't exist when the older engine was written.

But unlike all versions of MetaCard, you can choose "Save As" from the 
LC IDE's File menu and choose a format version you want the stack to be 
saved with.

All formats going back more than a decade are supported.  Of course if 
you use new objects or object properties those will be lost when saving 
to a format that doesn't support them, but of course if you're writing 
new code to take advantage of new properties you'd probably want to keep 
using a newer format anyway.

Better still:  once you've use the IDE's "Save As" and selected an 
earlier format, any time you use File -> Save in the IDE it'll continue 
to save the stack in that format.

So while we've always had to be mindful when adopting a new format since 
my earliest days with MC back in '98, now we have more flexibility with 
moving between current and older versions of the engine than we've ever 
had before.
