As far as a community calculator is concerned,
https://symbolibre.org/ is the only project with such a level of polish.
The schematics of the NumWorks calculators are openly accessible.
I've checked every day to see if TI updated the OS on their site for the TI-84 Plus CE, and still 5.4. I'm still going to stay at 5.4 or even 5.4.1, but never 5.5. Calculator programming is big at my school, so I will be sure to inform other users as well.
PM or email me if 5.5 is released yet.
I have also completely recovered from Coronavirus, so I'm good now. It was a looong two weeks with sitting in my bed and making programs every day.
Whoa man glad you recovered.
There will be a lot of news when the 84+CE version arrives, probably 5.6.
New milestone.
OS 5.5.1 which did remove asm programs support was only for the french
TI-83 Premium CE, not the international
TI-84 Plus CE.
It's not the expected 5.6 version yet, but now there is
OS 5.5.5 for the
TI-84 Plus CE and of course it removes asm as well, this time on the last
TI calculators still supporting it :
https://tiplanet.org/forum/viewtopic.php?t=24097&p=254657#p254657
A new major step just began in asm programs annihilation on the
CE...
The main new thing is
Python programming, but note it's only supported on the new BTS 2020
TI-84 Plus CE-T Python Edition.
The older
TI-84 Plus CE-T and
TI-84 Plus CE don't have the required
Atmel ATSAMD21 chip, you won't get
Python by just updating the OS.
So if you still decide to update your TI-84 Plus CE or TI-84 Plus CE-T, then have fun permanently damaging your calculators abilities.
Why is security on a calculator? Apart from safe testing who asked for it. also, students and teachers are prompted to hard reset calculators before using it for tests. There could have been other ways to "remove" Asm applications like OS only removes it on school calculator (yellow and black) based on serial number??. Or it disables asm applications when python is detected on the calculator. 🤦🏿♂️
TI Dev team, I am very disappointed in your lazy decision on how to deal with your "Security issue".
This has to be fixed even tho you remove the "Security issue". The calculator then get loads of exploits. And in the end, eventually, TI-Calcs will not be safe for testing. I guess the dev team was thinking about the now and not future. 🤷🏿♂️

I've looked on TI's website for OS 5.5, but still 5.4.
OS 5.5.5 (or 5.6) is not yet available on TI's site, but it did ship with critor's 84+CE-T Python Edition. If you really want a copy of 5.5.5, you can find it on TI-Planet:
https://tiplanet.org/forum/archives_voir.php?id=2639025.
Or just buy a TI-84+CE-T Python Edition, it's available. 🙂

you wish
Also OS 5.6.0 will do the same thing as 5.5.1 for TI 84 Plus CEs. I guess we'll be resorting to physically modifying our calculators if we can't use ASM/C/ICE. TI can't stop us from doing that to our current calculators! >🙂

Your dad's a wise man 😄
So if someone gives you a CE for Christmas, you can tell if they like you based on whether or not they have updated the OS XD.
It's finally out. Assembly will be gone forever. I upgraded my dummy calc that I don't care about anymore. I'll probably destroy it in a video.

Question: Can you downgrade 5.4 with an older version of TI-Connect CE?
Native code was never gone forever from the Nspire Clickpad / Touchpad / CX / CM series, which has a better security design than the TI-eZ80 series, and it's publicly documented that there's arbitrary code execution on the CX II. More generally, time and again, native code is always made accessible (again) on all closed platforms, sooner or later. Therefore, you should not think that assembly programs will be gone forever on the TI-eZ80 series - that just doesn't match what happened and will happen on other platforms 😉
Also, older non-Python 84+CE / 84+CE-T / 83PCE calculators whose boot code version is older than 5.1.5 do not have downgrade protection.
@Cemetech staff: for the sake of users, Cemetech really should add big fat warnings against OS 5.5+, like TI-Planet and CodeWalrus did. You didn't do it before to raise awareness, it's your choice, but now, it's high time you did it.

Yeah indeed, although we've been doing our best to inform users for months now, it seems it isn't enough. There's already at least one 5.6 victim :
https://github.com/calc84maniac/tiboyce/issues/113
Many more are coming if nothing's done.
Now that the summer vacation is nearing its end, I don't see any warning or mention of this on Cemetech's front page. I guess we'll have a whole bunch of disgruntled students who will learn that ASM/C is gone the hard way.
You might want to do something about that, Cemetech's admins. Because by now it should be painfully obvious that Texas Instruments is not going to back off on ASM/C removal and every single calculator website that I know of (TI-Planet, CodeWalrus, ticalc.org, Omnimaga) has either a banner or a news post about it with high visibility.
