This release includes numerous other small bug fixes. While the release fixes on bug fixes, new features were also introduced:

Recommendations

A list of similar works that we also track, generated by common relations, e.g. other works tracked by Lagotto cited by the same paper or bookmarked in the same ORCID profile. Available in the v6 API, e.g. here.

Identifiers as URIs

Starting with this release, the id for a work in the v6 API will always be a URL, e.g. http://doi.org/10.1371/journal.pmed.1000097, and the use of dx.doi.org has been changed to doi.org in all places.

Second-order Events

Lagotto 4.1 adds support for second-order events, i.e. it will track news items and blog posts that discuss a work in Lagotto. We do the same for scholarly articles that mention a tracked work in the body text (where we can search the fulltext), e.g. informal citations to datasets.
