Beta 16 is ready for download from your WordPress dashboard.

This release primarily addresses issues with retina images in the new post notification templates. In beta 15 we rolled in support for Thunderbird but inadvertently caused havoc with the mobile views. Very sorry. This new approach should make everything happy. Thanks for your patience.

While we were in there we redid a lot of the code that makes up the new post notification template. We adjusted the header area so it is now possible to create a header image which  fills the entire top area of the email.

Differences in how header images work

The email template will now display your header image differently, depending on what size the image is. There are two modes: Full width and Centered.

Full Width Header Images

It is now possible to fill the entire top area of the email template with an image. It will run across the top of your emails, completely filling the available area. Like this:

To display your image full width just be sure it is greater than 1440px wide. Postmatic will take care of the rest.

Centered Header Images

The centered header images that you have probably been using to this point are still available as well. So long as your header image is less than 1440px wide it will be displayed centered and at retina quality:

There are lots of little template tweaks and changes hiding in this release as well. Next we are on to beta 17 which will be an overhaul and simplification of comment notifications.
