Since Classic is looming around the corner, we wanted to make a statement on oUF's support for it.
We have no intentions of supporting both versions of the game, mostly because there is no parity or forward/backwards compatibility between the two versions. Supporting both versions in the same code base would be borderline impossible, and maintaining parity ourselves between two versions of oUF would deem impractical.
As such, oUF will not support Classic, more specifically, the oUF team won't.
If someone (singular person or a team) wants to fork and maintain a version of oUF that is compatible with Classic, feel free to reach out to us.
