This is a minor release of Ecto that builds on the foundation established by Ecto 2.
Ecto 2.1 requires Elixir 1.3+.
Ecto 2.0 introduced subqueries and Ecto 2.1 brings the ability to use maps to name the expressions selected in a subquery, allowing developers to return tables with conflicting fields or with any other complex expression such as fragments or aggregates:
posts_with_private = from p in Post, select: %{title: p.title, public: not p.private}
from p in subquery(posts_with_private), where: ..., select: p
Ecto 2.1 adds or_where and or_having that allows developers to add new query filters using OR when combining with previous filters.
from(c in City, where: [state: "Sweden"], or_where: [state: "Brazil"])
It is also possible to interpolate the whole keyword list to dynamically filter the source using OR filters:
filters = [state: "Sweden", state: "Brazil"]
from(c in City, or_where: ^filters)
