As reported on TI-Planet, the new TI-Nspire 3.1.0 is out! Unlike some people thought, it's not 3.1.1. According to TI-Planet, you can downgrade to 3.0.2 after installing the new 3.1.0.392 OS, since the minimal version number remained the same (3.0.2.1785). The boot2 was also left unchanged on the TI-Nspire and TI-Nspire CAS, while a new boot2 3.1.0.16 gets installed on the CX models.

What's new? According to the official website, the OS 3.1.0 supports the TI-Nspire Navigator on computer networks and better manages the battery when used with the TI-Nspire LabStation. We also got reported that the print() function from the built-in Lua language got removed, so serial port and sound stuff no longer works... A new (deprecated) function, gcinfo(), appears though.

You can download the new OS for all the TI-Nspire models (original, CAS, CX, CX CAS and even CM and CM CAS!) here, as usual, it's not recommended to install it without having taken the necessary precautions first (TNOC, DowngradeFix et al.).

EDIT: Critor has just reported that a TI-Nspire CM specific version of this OS has also been released. This operating system does include anti-downgrade protection (set to OS 1.7), but as this is the first version we know of it isn't all that important. 

Additionally, TI has released (possibly by accident) a version of 3.1.0 for the TI-Nspire CM CAS, a model which has never before been publically mentioned. So we might see a CAS model coming soon?

Does Luna still work with this?

Are there any other features they advertise? I'd think they'd wait for ndless 3.0 to come out, so they could block the exploit. This just means that ndless 3.0 has a high probability of working on more OSes, so I'm happy!

A specific 3.1.0 OS has been released for the TI-Nspire CM.

It includes a different 3.1.0.16 Boot2.

The OS downgrade protection is very low: minimal OS version is 1.7.2147.
But if older production CM OSes don't exist, this protection would have been useless... for now.

Do you want something exclusive that seems to be planned too?

TI has released (maybe by mistake) a 3.1.0 OS for a TI-Nspire CM CAS.
There is no mention of such a model on Google for now.
And Adrien didn't see anything like that when he was at TI-Dallas...

But the file does exist and is different from all other 3.1.0 files. Download it on TI-Planet!

Maybe the 1st post should be edited with the informations from my tow last posts?

Or maybe a separate "3.1.0 Chinese specific" news should be created?

Good question...

According to the name, it would return infos about the garbage collector? If my guess is right, it's not really something interesting indeed.

Edit: A quick Google search shows that it returns the amount of memory in use by Lua (in kilobytes).
