I love this change the most:

Ecto now will also warn at compile time of invalid relationships, such as a belongs_to that points to a schema that does not exist.

Thanks for the hard work!

[Ecto.Migration] Add reversible execute/2 to migrations

Blew my mind. Is Ecto able to automatically determine if the arbitrary SQL is reversible? Or does it just skip that execution on rollback?

Edit: nevermind. I see that it is execute/2, the second argument is what you execute on rollback. Makes sense.

Hah, I was just typing up a post!

My post was:

Just wanted to note that an awesome feature has been added to Ecto 2.2.0-rc.0 that was just released. select_merge (and select(blah, merge(bloop)).

This is a feature that has been wanted a few times here and so just want to point it out (I’ll be rewriting and simplifying a lot of my complex queries soon!).

See the docs for it at: https://hexdocs.pm/ecto/2.2.0-rc.0/Ecto.Query.html#select_merge/3

@mbuhot please open up an issue, we can easily support aggregates inside type/2 as well.

Do a hard refresh on the docs page. And I would love some feedback on the select_merge feature.
