Is there a CodeIgniter 3.x roadmap?

There isn't a CI3 roadmap, no.
There has been talk of a 3.2, with exceptions instead of returning errors, but no specific plan/date.
CI3 continues to get updates, including security fixes, and will for some time.
They may not be very frequent, but they are happening.
At some point, a year or two from now, CI3 is likely to transition to security fixes only, but we haven't announced or planned anything specific for that.

CI3 is stable enough that you should be able to keep using it for some years to come

In 4 versions, make a normal translation like Laravel, so that it is like right now + adding .json translation files

Here is how I did it, but I think it’s possible to implement it better, so I did it for version 3
