Oh right, but I mean TI ones. I was sure TI stopped selling apps althogether.
In case you are wondering where I went, I left Omni back in 2015 to form CodeWalrus due to various reasons explained back then, but I stopped calc dev in 2016 and am now mostly active on the CW Discord server at https://discord.gg/cuZcfcF

I think they have, but I don't expect they'll ever take those bits of code out.  And even if they did - even if they released new OSes tomorrow that did away with all the old protection mechanisms - I'd still say it's worthwhile to remain compatible with the older OSes.  I mean, personally, I'm still using 2.30 on my 84+, and given the state of the newer OSes, I don't plan on upgrading that in the forseeable future.  I think both my 83+es are running 1.19 now, but I kept 1.14 for a very long time, for the sake of program compatibility.  I'm sure I'm not the only one.

I think BrandonW always recommends to update to 2.43 and 1.19 but discourages using 2.53 MP. However, I guess if you never have issues with older OSes you don't really have to bother. I personally used 1.14 for ages as well, too, then stuck to 1.18 for 2 years. The only problem with older 83+ OSes is that they have a different ASCII charmap I think, or something related to ASCII is different, and as result, certain games using some characters will only send on a calc running 1.15 or higher.

They are missing a few characters, namely [email protected]#$&`;\|_%. They were added to allow compatibility with the TI Keyboard. 1.16 also added a few characters, but they are rarely used. Some of them are the arrows, the … character and also ß, which is used in German.

Those OSes also broke compatibility with old ones, though. The 256 char-long string of 3x3 black squares is gone, for example. Illusiat 6 final dungeon, for instance, no longer shows up properly past OS 1.15.

Is it completely gone, or is it just replaced with a more normal token?

It became an up arrow, if I remember. You can see how the original token looked like at 2:37 in this video:

This is a 2 bytes token, by the way.

So I sent this to my calculator and tested it out on an Axe app, but it said the length was wrong and refused to sign it.

That's probably because of the bug in 0.4.7 that causes it to not update the length field.  This has been fixed for the patch.
