Hello everyone,
since this community is still very active and i just acquired second nSpirte calculator (First one is nSpire CX II-T 5.3.0.564 with Ndless installed of course) i need some advice from You for this, new one.

Calculator is nSpire CX with :

OS version: 3.2.0.1212
Boot1: 3.0.0.99
Boot2: 3.1.0.16
HW version: E (P-0712E)

First greater than current OS version supported by Ndless is 3.6.0.546.

But on 3.x there are also :

3.9.0.463
3.9.1.38

and on 4.x series :

4.0.3.93
4.2.0.532
4.4.0.532
4.5.0.1180
4.5.3.14
4.5.4.48

So, my questions are :

1. Should i stay on 3.x or move to 4.x OS and why ?
2. Will i loose something eventualy switching from 3.x to 4.x OS ?
3. Do you have recomendation for some specific OS version of those supported by Ndless listed above or i should go with the latest supported in 3.x/4.x ?

Obviously i have the ability to chose what to do so, i need help from this community in order to choose the best option for this calculator.

Personally, I'd go to the latest 4.x supported by Ndless, so that you can have the maximum amount of features on all sides, from ti and the community.

Well, that was my first thougth but before i upgrade OS to the latest supported by Ndless, i just wanted to consult much more experienced from me.
Should i update straight to the latest, 4.5.4.48 or should i update gradually up to that version, or to the latest 3.x and then to that latest ?

You can go right ahead to the 4.x version. Gradual steps were initially required for the very first versions (1.x to later ones) due to boot updates with incompatibilities
