Dolphin is not a legacy platform. Dolphin 7 is, which means that it is still supported and updated, but not recommended for new projects. The new UNA-powered Dolphin is the much needed update of the architecture designed nearly 20 years ago.

Forking Dolphin 7 under current license terms would require end-clients to obtain a license from Boonex, which is also bound by other co-licensing commitments as well as interchange commitment with UNA Pro account. Your end-clients may be at risk of violating see more multiple licensing terms if you fork without appropriate consent and consultation.

If you want to contribute to the development and improvement of Dolphin 7, you can fork it on GitHub and request to commit your changes back to the platform - we would then be able to review them to ensure that quality and security is maintained.
