Version 0.30.0

MJML, HTML, and Plain-Text Templates, Content Slots, and Transactional Emails

Breaking Changes

• In MJML campaigns, Liquid is now rendered before MJML. This means that
  the previous convention of wrapping control-flow tags such as {% if %}
  in <mj-raw> elements no longer works. This release automatically migrates
  this pattern in existing campaigns to use the new <keila-code> element.
  This new element can be placed at any level of an MJML template/campaign/message
  and is removed cleanly before MJML is rendered.

Added

• New API for sending and rendering transactional emails: one-off messages
  can be sent with the POST /messages and previews rendered without sending
  with POST /messages/actions/render.
• New API for managing templates.
• Added support for MJML, HTML and plain-text templates.
• Added content slots (<keila-content>) for MJML, HTML, and plain-text templates
  which can be filled in the campaign editor and set via the API.

Improved

• The MJML editor now allows scrolling the code editor independently from the preview and
  has better autocomplete for MJML.
• Improved handling of image resizing in the Block Editor
• Improved handling of unsubscribe links in welcome and double-opt-in messages
• Improved validation of user-provided email addresses
• Added descriptions for API tags in the OpenAPI documentation
• Replaced the tzdata timezone database with tz, removing the need for
  runtime timezone-data updates
• Replaced the HTTPoison HTTP client with Req

Fixed

• Fixed a regression with linked images in Markdown campaigns
• Fixed a regression where List-Unsubscribe and Precedence headers were no
  longer sent with delivered campaigns
• Fixed incorrect fuzzy translations (manual corrections for German and French,
  machine translations for other languages)
