I linked to you a video tutorial from 2018, https://www.youtube.com/watch?v=KPEqYtEd-zY . Can you show me what code from that tutorial has broken in the SciML/DiffEq landscape? I know that A_mul_B! changed to mul! when Julia v1.0 came out in 2018, but is there anything else that changed? Let's be concrete here. That's still the tutorial we show at the front of the docs, and from what I can tell it all still works other than that piece that changed in Julia (not DifferentialEquations.jl).

I'm sorry, but non-concrete information isn't helpful to anyone. It's not helpful to the devs (what tutorial needs to be updated where?) and it's not helpful to passerbys (something changed according to somebody, what does that even mean?). I would be happy to add a backwards compatibility patch if there was some more clear clue.

> I think passerbys should be made aware of the state of things in the language without spin from people making a living selling it.

The DiffEq/SciML ecosystem is free and open source software. There is nobody making a living from selling it.
