TI-Nspire OS 4.2 released
« on: February 16, 2016, 05:32:21 pm »

Bit of a bad news today, as with most TI-Nspire OS releases, the newest OS 4.2 is out for release as of today. Same Boot1 and Boot2, but among the new features we have new IO functions (Get, GetStr and Send) and, most importantly, as you can guess by now, it blocks Ndless 4.0.3, as released last month, without any way to downgrade.

So in short, as we say almost every release of the OS...

DO NOT INSTALL THE NEW NSPIRE OS 4.2 IF YOU WANT NDLESS.

Well, until a new version of Ndless fixes it all. (EDIT 19/02/2016: Which is coming soon already?)

Dang I wanted to post the news. It was gonna be a copycat of the OS 4.0 news with some strikethroughs with small replacements next to them, because that's pretty much what this OS is, and I'm not surprised it comes out right after Ndless 4.0.3. I'm betting 4.2 was not supposed to come out before next school year, but that Ndless 4.0.3 made TI rush it to the market.


Also this OS might be problematic in France, because in June 2015, many French teachers who monitored exams tried to instate their own laws and restrictions during exams, such as disallowing students from using their Nspire CX calc to view documents even though they were allowed to and worse.

Wait, they fixed a bug? O.O That's usually rare, because OS 3.6 still had bugs dating all the way back in OS 1.1 or so.

As for Get/GetStr/Send, do they also work while the other calculator is busy doing stuff? (for example, inside a For loop) On the 83+ series, GetCalc stopped working if the other calculator was busy and only worked if it was Paused or not inside a program.

Do the new IO functions work in lua? Because if so I am definately upgrading(I dont really use any ndless apps except for ndoom and nclock and many other apps crash/reset my calc anyways). Also how are they used? Are they just for calc to calc or can you communicate between the nspire and a computer or some other device?

Eh then its not really worth it. I'm going to stick with os 4.0.3 for now.
Also are there any other changes(and where can I see the list of them) made with the new os?

Critor just reported that there is now a Wait command, to add a pause of a few seconds to the program. Kinda like on the HP Prime.

There is no changelog yet. Maybe there will be one at T3?

They tell what's interesting in math courses and that's it, so teachers can understand what new they can teach. Nothing about the boring internals nobody cares about. (except us power users of course :P)
