+This seems stable so far. This release adds mail configs to the env file and updates to the most recent version of Ghost. 
+
+I've only tested the mail settings with SMTP so far, so your mileage may vary. Adding the mail settings means you can add other contributors to your Ghost instance, which you couldn't before.
+
+If you have any issues, Ghost is using nodemailer for mail under the hood so check their docs for any config options you may need. Happy to help if you do notice anything odd.
