In Detail

This release contains some new features and all of the theming & API tools needed to make the most of them.

The new slack integration allows you to automatically post to slack when a post is published. This feature will likely move to an internal app, and then a default installed external app over the coming months. This is our first experiment with integrations and we're looking to do more.

The subscribers feature is implemented, as much as possible, as an internal app. The tools it provides, such as the subscribe page, theme helpers & API endpoint, are only available when the feature is enabled in labs and there's a new helper for detecting if it is enabled from within a theme as well. See the support guide and theme docs for more details.

Twitter & facebook fields have been added both to users, and to the general settings screen. These store only the unique part of the URL - the twitter username and facebook page name or username. These values are available via the API and also in themes, where helpers have been added to create URLs.

Support for HTTP2 Preload headers have been added, but are currently off by default. To enable them, you need to set preloadHeaders to a numerical value in your config.js file, where the value represents the number of entries stored in the cache: e.g.

production: {  
  url: '',
  preloadHeaders: 100,

Long term, this feature will likely be enabled by default. Short term, users on Ghost(Pro) can contact [email protected] to ask for this feature to be enabled.

Theme API Changes

Breaking Changes

The breaking changes to the theme API are explained in detail in this blog post.

Other Changes

The theme API has a few additions in 0.8.0 in line with the new feature additions:

  • The new [email protected]}} global allows you to detect if a labs feature is enabled.
  • Both [email protected]}} and {{author}} now have twitter and facebook properties which contain the unique username / page name provided in the admin panel. Two new helpers: {{facebook_url}} and {{twitter_url}} have been added to make it easy to convert the usernames into full URLs in themes.
  • You can now add a new subscribe.hbs template to override the one provided by Ghost when the subscribers feature is enabled in labs. This comes with a full suite of helpers such as {{subscribe_form}} as well as adding a new context.

See the theme API docs for full details of what changed in Ghost 0.8.0. The theme documentation is frequently updated with more details and better examples. Please also use the suggest edits feature if you find something is missing or out of date.

Public API Changes

The addition (and removal) of several new database fields in Ghost 0.8.0 will result in minor changes to the Public API:

  • posts, tags and users all now have a visibility field
  • tags no longer have a hidden field
  • users & settings contains a twitter & facebook field
  • posts have a currently unused mobiledoc field

As the hidden field was not yet in use, this is not expected to result in any breaking changes.

All Ghost(Pro) users are being automatically updated and will be running Ghost 0.8.0 shortly. You're welcome :)
