After releasing the new logic-v2
result scoring algorithm in September, we're planning to make it the default used by the OpenSanctions API service when no other algorithm is specified (or the best
algorithm is selected). API users can prepare for this change in two ways:
logic-v2
. The new system significantly reduces false positive alert rates and improves match quality. We also plan to make this new algorithm the focus of future feature enhancements and precision improvements.algorithm=logic-v1
as part of your query string to opt out of this change. This will freeze the use of logic-v1
, the current best
/default algorithm. This option is recommended for API users where scoring changes may require a regulatory approval/notification. We may choose to fully retire logic-v1
within the next 24 months.Please feel free to reach out to the support team with any questions regarding the new scoring algorithm.

In an effort to simplify our Matching API, we are removing the cutoff
parameter. Once this change becomes effective, only matches, i.e. those results scoring higher than threshold
will be returned. If you care about low-scoring results being returned, please adjust the threshold
parameter instead. The match
property on the returned results will remain and function as before, and match
will be set to true
for all results once this change becomes effective.

We have begun a two-step migration in the /match API response format that affects users relying on the features
and matcher
fields.
The matcher
field in /match
responses will be removed after February 27, 2026. Equivalent information is available via the /algorithms
route (free to use).
A new explanations
field has been added that is a strict superset of features
. In addition to the partial scores produced by each component of the matching system, it includes textual descriptions of the matching decisions from each of these subsystems. These descriptions are designed for display in analyst workbenches or can be passed to generative AI tools to help interpret screening alerts. The features
field will be removed after February 27, 2026. Users should update their applications to consume explanations
before this date.

We will officially end support for yente 3.x at the end of March 2025. This means we will be unable to provide support for this version, and will not guarantee that new versions of the data will be correctly and completely loadable by the old application release.
To ensure continued compatibility and access to the latest features, we strongly encourage all users to upgrade to the latest version. For detailed instructions on upgrading, visit our documentation page on upgrading yente.

This release updates various dependencies, introducing new fields in the followthemoney schema and bringing in security patches for the web stack dependencies.
We're also implementing the Reconciliation API's Data Extension protocol for the first time, allowing users to enrich OpenRefine tables with new columns using the API.

yente
4.1.0 (release page) is a minor patch release. It introduces clearer error reporting during index runs, and fixes the number of matches reported in the total
section of the /match
API. Various dependencies have been updated to their latest version, including followthemoney
.
