When does Ruby 3.3 reach end of life?
Ruby 3.3 reaches end-of-life on 31 Mar 2027 — about 9 months away. After that date it stops receiving security patches.
Is Ruby end-of-life?
No — Ruby still has supported release lines (4.0, 3.4, 3.3). But individual older versions are end-of-life, so what matters is the specific version you run.
How do I know when my Ruby version reaches end of life?
Check the version you run on its product page, or monitor Ruby on IsItPatched to get an email alert before the release line you use reaches end-of-life — so you can upgrade in time.
