We’d like to note two sets of changes that we feel can not wait for the monthly Tech Bulletin announcement process:
wikipediaUrl changes (wikidata dataset)
We will be progressively releasing corrections to the values in the wikipediaUrl property. We are aiming to correct about 10,000 entities per day until the full cohort of about 230,000 entities are fixed. This is a correction to a mistake in how wikipedia URLs were generated in the notified disruptive release of 16 March 2026. We believe gradually releasing the correction will have a lower impact for customers whose systems struggle to cope with the scale of massive amounts of changing data at once.

rekey and modifications in us_sam_exclusions
About 57,000 entities in the us_sam_exclusions dataset will be assigned new source IDs over the next three days. We will do our best to ensure the majority are assigned their current canonical identifier, or assigned a new canonical identifier linking them to their current source ID. Any false-positive decisions should be reusable if canonical identifiers and referents are handled correctly. See our Identifiers and deduplication documentation for details. This change was necessitated by the publisher, the General Services Administration (GSA), removing the SAM Number field used as the identifier for affected entities. While this change falls within our definition for disruptive data changes, we determine that it is sufficiently urgent to release this change immediately instead of announcing it in the upcoming Tech Bulletin and releasing in the next scheduled disruptive release on 15 April.
As part of preparation for this, we noticed that the GSA has also changed a significant portion of the data, including changing capitalised values to normal capitalisation. This will cause modifications to roughly 160,000 entities.
