Highlights for Invenio v3.2

Files bundle

We have released four new modules as part of the new Files bundle:

To understand more about how to use the new Files bundle see our integration guide on https://invenio.readthedocs.io/en/latest/tutorials/handling-files.html.

Elasticsearch v7 support

Invenio now supports Elasticsearch v7.

Marshmallow 3 compatibility

Invenio now support both Marshmallow v2 or v3. The support is done via a compatibility layer, that allows Invenio to work with either schemas from v2 or v3. This should allow users to upgrade to Invenio v3.2 without being forced to upgrade their Marshmallow schemas immediately to v3.

We advice all users to start planning an upgrade of their Marshmallow schemas from v2 to v3 as the upgrade is non-trivial and needs proper testing due to significant differences between Marshmallow v2 and v3.

Invenio will continue support for both Marshmallow v2 and v3 for a transition period to allow users to upgrade at their own pace. After the transition period Marshmallow v2 support will be deprecated and removed from Invenio.

For information about how to upgrade see https://invenio.readthedocs.io/en/latest/tutorials/upgrade-marshmallow.html.

Search index prefixing

Elasticsearch does not support the concept of virtual hosts and thus with previous versions of Invenio it was not possible to share an Elasticsearch cluster between multiple Invenio instances.

We have now added support for index/alias/template prefixing, so that all names can be prefixed with a string and thus allows multiple Invenio instances to share an Elasticsearch cluster. Note, that this is only name prefixing, thus technically two Invenio instances will can read each other indexes and thus must trust each other.

Read more about the new feature on https://invenio-search.readthedocs.io/en/latest/configuration.html#index-prefixing.

Maintenance policy

Invenio v3.2 will be supported with bug and security fixes until the release of Invenio v3.4 and minimum until 2020-12-20.

See our maintenance policy.

What's next?

In Invenio v3.3 we are planning to release the Statistics bundle including:

  • invenio-stats
    • Invenio module for statistical data processing and querying with support for collecting COUNTER Research Data Usage Metrics compliant statistics.
  • counter-robots
    • Library for COUNTER-compliant detection of machines and robots.

In addition to the Statistics bundle, we will also release final versions of the following two modules:

  • invenio-index-migrator
    • Elasticsearch index migrator for Invenio (aka zero down-time reindexing and index migration).
