Well. This is the first step in "me started working on decimal again".
The Decimal spec changed: it has new operations, but also changed the
behaviour of some already-present operations (right now I'm pulling my
hair because of a corner case of rounding that must behave different
in quantize).

What I don't know is: these changes will be considered as "bugs" and
backported to <2.6, or it will be considered as little changes that
will join the bigger changes in 2.6?

If the former, I agree with you that this change should be reversed
(note that I didn't realize these losses at its moment, but everybody
learns, ;).

What do you think?

It changed from "ValueError, 'foo'" to "ValueError('foo')". Don't
remember when this was introduced in the language, though (didn't find
it overlooking the "What's new" docs...).

Thank you!
