Changes to the license models


What DALICC changed in its curated models, when, and why.

A license model is corrected when a reading of the legal text turns out to be wrong. Every correction changes what the compatibility checker answers, so each change below names the reason behind it and links to the record it was made on.

  • Upstream Compatibility License v1.0 version 3 2026-10-02

    changed Duty: Share alike

    was Duty: Share alike

    Manual edit The share alike names the ways of combining it reaches and quotes the sentences that settle them (dalicc:reachesCombination, dalicc:reachEvidence).
