Enable the new setting "post excerpts in emails" to send excerpts
instead of complete posts in notification emails. Control the length of
excerpts with the "post excerpt maxlength" setting.
This feature adds the ability to customize the HTML part of all emails using a custom HTML template and optionally some CSS to style it. The CSS will be parsed and converted into inline styles because CSS is poorly supported by email clients. When writing the custom HTML and CSS, be aware of what email clients support. Keep customizations very simple.
Customizations can be added and edited in Admin > Customize > Email Style.
Since the summary email is already heavily styled, there is a setting to disable custom styles for summary emails called "apply custom styles to digest" found in Admin > Settings > Email.
As part of this work, RTL locales are now rendered correctly for all emails.
This change both speeds up specs (less strings to allocate) and helps catch
cases where methods in Discourse are mutating inputs.

We no longer include previous replies as "context", instead
we include and excerpt of the post being replied to at the bottom
of notifications, this information was previously missing.
Users may opt in to emailing previous replies if they wish
or opt out of "in-reply-to" which makes sense in some email clients that
are smarter about displaying a tree of replies.
- always means we always send previous replies with every email
- never means we do not
- "unless previously sent" ... is the default, in which we only email you each reply once
The default_email_previous_replies site setting can control this toggle
