Triton v3 is now default
Triton has a major update. You can read our previous info about this at Preparing for new Triton, and our “what has changed” in Triton issue #1593.
You might get SSH host key warnings.
What is Triton v3
It has the same name, and importantly the same user accounts and data, but all the software and operating system is changed. In particular:
All software modules are different
Any software which has been complied will need to be re-compiled.
Why, and why now?
Triton’s previous operating system was released in 2014. Security support runs out at the end of 2024 May, and it has to be updated. Stability is good for research, so we try to reduce the number of changes (compare)
We realize that a change is very disruptive and painful, especially since the expectation is that Triton never changes. But an old operating system makes problem for users too, and they have gotten more and more over the years.
What to do
Most of the transition for different types of software is described in Triton issue #1593.
