Another one from 2019:
I just stumbled upon this recent translation of an Italian article (published some months ago) that contains a link to a document uploaded in May 2023, which is an August 2019 agreement between Hyperion and Trevor Dickinson as per which Trevor acquired (in source-code form) joint ownership of "all software assets owned or co-owned by HYPERION which are shipped with or incorporated in Amiga OS 4.x" for the sum of 47.500 EUR.
I seem to have missed this until now. Has this before been mentioned or discussed anywhere?
