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+:

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.
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*.
You should attend the NCTM Chicago 2024 on September 26 or 27.
You'll be able to test directly on the Casio booth if 3rd party addins work on the fx-CG100 with OS V2 beta, and if not ask Casio to bring back their support in a future OS V3 update.

Maybe Adriweb will comment more about that, it seems that the sales of the fxcg50 are in the 100K range/year, while the fxcg500 (classpad) sales are much smaller (less than 5K/year). Currently amazon.com is displaying sales of 2K+/month for the fxcg50 and 50+ for the fxcg500 (we are about the peak for back to school, by comparison the ti84 is at 80K+). It seems that the classpad will be discontinued soon, in favor of the classpad.net. Casio would no longer sell CAS calculators, CAS would be available on classpad.net only. It might be one of the reason to disable addins on the fxcg100: make sure students can not run (Khi)CAS on the fxcg100. If this is true, then I encourage students interested in a not too expensive CAS calculator (aka TI Nspire CX2 CAS) to look at the competition : KhiCAS is also available on the Numworks (
