Upgrade Paths

Migration guidance between major versions — breaking changes, effort estimates, and tips.

1.14 1.15 Low Difficulty
Est. < 1 hour

Breaking Changes

  • OTP 24+ required (drops OTP 23)
  • Compilation warnings for missing @doc before @spec
  • Mix.install/2 improvements

Migration Notes

Non-breaking. Update OTP if needed. Fix compiler warnings.

1.15/1.16 1.17 Low Difficulty
Est. < 1 hour

Breaking Changes

  • OTP 25+ required
  • Duration type and calendar duration support
  • Set-theoretic types in guards (developer preview)

Additive release. The new type system features are opt-in. Update OTP to 25+ if still on 24.

Version Risk Assessment

Evaluate risk factors before choosing a version for production.

Version EOL Risk CVE Risk Ecosystem Cloud Support Overall Recommended Action
Elixir 1.13 and below High Low Outdated Legacy High Upgrade — missing years of improvements and OTP compat
Elixir 1.14/1.15 Medium Low Supported Full Medium Update to 1.17 — painless upgrade
Elixir 1.16 Low Low Active Full Low Recent — update when convenient
Elixir 1.17/1.18 None Low Active Full Low Current — recommended

Risk combines OTP compatibility, hex package ecosystem support, and version currency. Assessed as of March 2026.

Frequently Asked Questions

Common questions about Elixir releases and lifecycle.

How long are Elixir versions supported?
Elixir supports the latest minor version with bug and security fixes. Previous minor versions only get critical security patches. Major versions are backward compatible within the 1.x series. Elixir has been on 1.x since 2014 with no breaking changes.
What Erlang/OTP version does Elixir require?
Each Elixir version specifies a minimum and maximum OTP version. Elixir 1.17 requires OTP 25-27. Elixir 1.16 requires OTP 24-26. Always check the compatibility table before upgrading either Elixir or OTP.
Is Elixir good for web development?
Elixir with Phoenix is excellent for real-time web apps. Phoenix LiveView enables interactive UIs without JavaScript. The BEAM VM handles millions of concurrent connections. Companies like Discord, Pinterest (ads), Brex, and PepsiCo use Elixir in production.
What is Phoenix LiveView?
LiveView renders HTML on the server and pushes updates over WebSockets. Users get interactive UIs without writing JavaScript. It handles real-time features (chat, dashboards, forms) that traditionally required React/Vue. Since Phoenix 1.7, LiveView is the default approach for new projects.
Is upgrading Elixir difficult?
Elixir has been remarkably stable. The 1.x series has maintained backward compatibility since 2014. Most upgrades are painless: update the version in mix.exs, run mix deps.get, fix any compiler warnings. The main concern is OTP version compatibility.
