Casio is introducing in 2024 a new color calculator in France, the Graph Math+, and it's international equivalent is expected to be released in 2025 as the successor of the FXCG50. More info in French on the Math+: https://www.planet-casio.com/Fr/forums/topic17728-1-decouverte-graph-math-v100-de-rentree-2024-grace-a-son-manuel.html
The important point is that the current Math+ OS (version 1) does not support addins, therefore applications like KhiCAS will not be available on the Math+, at least in 2024
Casio announced that a version 2 of their OS will be released in 2025, but did not clarify it's position with
respect to 3rd party addins. If you like the freedom to install addins on your Casio calculator, maybe you should contact Casio and tell them your opinion!
I have added a similar message to KhiCAS documentation. If we are enough, it may change the final decision! We are many to be potentially impacted: I got more than 7000 downloads of KhiCAS documentation since the begin of this year.

I have sent a message asking their position on third-party addins and strongly encouraging them to include support in future versions. Hopefully our attempts will prove successful!

Thank you very much.

Could you also share the message ?
Privately, if you prefer.

Who did you send it to ?

Since I'm not important enough to be in contact with Casio I just went ahead and sent it through the CS form on their website. Who knows if it'll go anywhere but I thought it was better than nothing, and maybe I can look around and try somewhere else as well.

However, as a result of sending it through the online form I don't have any copy of what I sent. I'm assuming that I'll probably receive a copy of my original message after a response, and I'll message it to you then.

And it's confirmed, the great fx-CG50 is also being replaced but for back to school 2025, with the fx-CG100 :

Limiting the memory to 4.5 MB seems like a rather odd decision!
I use an fx-CG50 AU and the memory limit is quite annoying for adding large addons like KhiCAS - doing this for all fx-CG100 users sounds like a strict downgrade.

If addins remain unsupported, the 4.5M limit is not the main downgrade.
I hope many readers here will react and tell Casio it's *bad*.
