apparently, there's a issue with installing uncertainties==3.0.1.

Also, I just noticed that UnitRegistry.default_format does not have a documentation entry, and that that's actually a property that sets class attributes on Quantity, Unit, and Measurement.

Yes I will make PR to resolve the error for uncertainties

Should be okay if you rebase @keewis

@hgrecco, this should be ready for reviewing and merging, after which we can issue the bugfix release we talked about in #1407 (maybe include #1422, too?)

Gonna look into this. but looks good so far !

@keewis can u rebase to fix conflicts

@hgrecco, @jules-ch, I think this should be ready for a final review. It would probably be good to include this, as well as #1422, in the bugfix release (which we should try to release soonish).

@keewis can you just change the condition that is duplicated to use if not mspec and default_mspec:
Idk if you received the notifications when I commented those lines.

sure

Idk if you received the notifications when I commented those lines.

I didn't (and I also can't see them anywhere), which is why I was confused when you posted #1450 (comment). Can you check if those comments are still pending and submit if so?

They are still pending, can't you see them? Weird
I can make those changes directly if you want.

if it says "pending" you have to submit the review

Oh I see, I thought those kind of review comments were automatically sent. My bad then.
Well I've just learned something it seems q_q

I like this PR and it is a great idea to split uspec and mspec early on
