Released 2018
Narrowed from '2018-10' to year-only: Cambridge Semantics first previewed the underlying product (AnzoGraph) in February/May 2018, with the October 2018 date in the current record reflecting the later standalone-download milestone rather than first public availability. The product keeps this original date under its current name, Altair Graph Lakehouse (rebranded 2025).
