Phoenix 1.3.x to 1.4.0 Upgrade Guides
View phx-1.4-upgrade.md

Phoenix 1.4 ships with exciting new features, most notably with HTTP2 support, improved development experience with faster compile times, new error pages, and local SSL certificate generation. Additionally, our channel layer internals receiveced an overhaul, provided better structure and extensibility. We also shipped a new and improved Presence javascript API, as well as Elixir formatter integration for our routing and test DSLs.

This release requires few user-facing changes and should be a fast upgrade for those on Phoenix 1.3.x.

Phoenix Drain Stop
View drain_stop.ex
defmodule DrainStop do
@moduledoc """
DrainStop Attempts to gracefully shutdown an endpoint when a normal shutdown
occurs. It first shuts down the acceptor, ensuring that no new requests can be
made. It then waits for all pending requests to complete. If the timeout
expires before this happens, it stops waiting, allowing the supervision tree
to continue its shutdown order.
DrainStop should be installed in your supervision tree *after* the
EndPoint it is going to drain stop.
