Estimated Next 13 version support?

[chaepling]

Summary

Hi, my project is currently using app router with Next 13, and I am wondering the estimated support date for Next 13 and the pages router. I understand that Next 15 also supports pages, but if the support term is gonna be short, I have to migrate all my apis.

Thought about upgrading to Next 15 immediately, but most of the libraries I use doesn't support React 19 yet. So my plan is to upgrade from 13 to 15 right away if I still have some time!

Please let me know, Thanks!

You can now refer to the https://nextjs.org/support-policy document.

Good to know that:

In rare circumstances, depending on the severity of the underlying bug, we will patch versions of Next.js that are outside of our LTS policy.

Pages Router will still be supported though. #56655 (comment)

In short, we're committed to supporting the Pages Router for many years in the future. And then maybe longer even. We believe backwards compatibility is incredibly important, which is why the same features from Next.js 1.0 work in Next.js 14 today (through the Pages Router).
