Which Updates Are Must-Install — Urgent vs Optional

Not every update is urgent. Use the release notes to tell the difference.

Urgent — install within days

• Security patches addressing active vulnerabilities.
• Advisories that call out specific affected models.
• Fixes for critical bugs in widely-used apps.

Optional — install at your own pace

• New coin or protocol support you don't use.
• UI-only improvements.
• Internal refactors without security impact.

Rule of thumb

If the release note mentions 'security', treat as urgent. If it mentions 'feature' or 'improvement', treat as optional.

Safety reminder: Use only the official Ledger site and Ledger Live. Never type your recovery phrase or PIN into a webpage and never share them with anyone. Pause and verify the moment anything looks unusual.
