Mysql support is not implemented at the moment. If there's someone paying for the development we could have it. You're of course also free to contribute it yourself to the open source version, then it wouldn't need to be part of the commercial version.

Some more background on why IHP has a paid variant can be found here: https://ihp.digitallyinduced.com/blog/6392ad84-e96a-46ce-9ab...

I don't get it. How can it be part of the commercial version if it is not implemented.

Not OP, but it sounds like MySQL support isn't out yet. So I think the business plan can help them get paid to implement it. No clue if that means the FOSS version would receive those upstream changes once it's done.

software needs work and devs have bills. its unfortunate but we don't have a government currently giving grants to open source devs yet.
