 We're still working with Node.js 8.11.4 as the upgrade to Node 8.12.0 got postponed to the Meteor 1.8.1 release. If you're itching to play with it, you can run `meteor update --release 1.8.1-beta.n` from the directory that you've got the core `reaction` project installed. There may be some additional speed improvements related to Meteor's use of `Fiber`s that come along in this version.
 
+We've also updated the our base docker image to use Meteor 1.8 (#4760)
+
+## Email Sending
+We've extracted the core email sending functionality into a new `reaction-email-smtp` plugin which is `included` and created a new `sendEmail` event which is emitted for each email job. The core smtp email plugin now listens for these events and sends an email if an SMTP provider is configured. By doing this we've made it possible to create plugins which send emails via an API rather than via SMTP.
+
+The email provider config form found at Dashboard -> Emails -> Mail Provider is now also able to be overridden. Plugins can use register.js to provide a React component to use here.

 ## GraphQL API
-We've added a primaryShop GraphQL query & resolver, eliminating the need to first query for the primary shop ID, followed by another query for shop by ID.

+## Breaking Changes
+In #4749 we changed the names of our included payment method plugins. We've included a migration to automatically update any existing installation, but if you have custom code that relies on these payment method names you may need make some changes.

 ## Chores
 We've been ignoring some of our integration tests as the in-memory MongoDB they rely on has not been working effectively. Previously we did this by skipping our entire `test:integration` tests in CI, we're now just skipping the tests that are failing due to this db incompatibility and have plans to address this soon.
