Deprecations: * The API versions 1 and 2 (also known as the REST API, ie /api/rest/* will removed in favour of the version 3 (action API, /api/action/*), which was introduced in CKAN 2.0. The REST API will be removed on CKAN 2.8. * The default theme included in CKAN core will switch to use Bootstrap 3 instead of Bootstrap 2 in CKAN 2.8. The current Bootstrap 2 based templates will still be included in the next CKAN versions, so existing themes will still work. Bootstrap 2 templates will be eventually removed though, so instances are encouraged to update their themes using the available documentation (https://getbootstrap.com/migration/) * The activity stream related actions ending with *_list (eg package_activity_list) and *_html (eg package_activity_list_html) will be removed in CKAN 2.8 in favour of more efficient alternatives and are now deprecated. * The legacy revisions controller (ie /revisions/*) will be completely removed in CKAN 2.8. * The old Celery based background jobs will be removed in CKAN 2.8 in favour of the new RQ based jobs (https://docs.ckan.org/en/latest/maintaining/background-tasks.html). Extensions can still of course use Celery but they will need to handle the management themselves.
