CKAN 1.8 released

October 22, 2012 in Feature, Releases

The CKAN team is pleased to announce the release of its new major
version, CKAN 1.8. Thanks to all the team and external contributors
who have made it possible!

This release includes new features like the ability to follow users
and datasets, and visualize their activity on a dashboard, and a
completely revamped version of the Datastore. The new version of
the Datastore is powered by PostgreSQL, which avoids having to install
extra dependencies and allows us to support more powerful features,
like a full SQL query interface. Users of the previous version of the
Datastore based on ElasticSearch can contact the mailing list for
details on how to migrate their data to the new version.

Apart from new features, we are working hard on internal refactorings
to make the CKAN code base more maintainable and provide a more solid
integration for extensions, making it easier to build them and upgrade
them between CKAN versions. Some of these changes have been included
in this release: have a look at the “API changes and deprecation”
section in the CHANGELOG to see if you need to update any existing

We have also made available version 1.7.2, which contains important
bug fixes for those users that want to stay on the CKAN 1.7 line.

Please refer to the documentation for instructions on how to install
or upgrade CKAN, either via packages or from source, and feel
free to contact the mailing list or the IRC channel if you have any

API changes and deprecation

  • Template helper functions are now restricted by default. By default only
    those helper functions listed in lib.helpers.allowed_functions
    are available to templates. The full functions can still be made
    available by setting ckan.restrict_template_vars = false in your ini file.
    Only restricted functions will be allowed in future versions of CKAN.
  • Deprecated functions related to the old faceting data structure have
    been removed:, facets.html:facet_sidebar(),
    Internal use of the old facets datastructure (attached to the context,
    c.facets) has been superseded by use of the improved facet data structure,
    c.search_facets. The old data structure is still available on c.facets,
    but is deprecated, and will be removed in future versions.
