When in doubt, return to the format versioning policy:

The interval type addition is a MINOR version increase in the format

Ok, so more accurately, it is not a format change, it's a format
addition ;-)
This sounds pedantic but a format change would potentially break
compatibility (for example if

Ok, so it sounds less like a "library" dependency and more like the
relationship between C++ specification and compiler or between browser
features and browsers. Does an implementation have to implement the
1.0 spec before implementing features in the 1.1 spec? I would assume
no. Given that we m

Hi,
Thanks for bringing this up.
AFAIK, this has always been an issue because we do not require all
implementations to support a type prior to releasing that new type in the
spec. Concrete example: map has been released for a while, but Rust does
not support it yet. Same for interval, where we st
Hi Weston,
I think one other issue that we might want to discuss is releasing the
format separately (i.e. as soon as we make a change to it).
My thoughts:
Can an arrow library adopt a new format version in a minor release?
I agree the answer is yes, and some issues might arise if minor releases
We now have independent releases. There has been some discussion (not

I think this brings up a few questions...
