What a Ledger Firmware Update Is Actually For — Security Fixes vs Feature Upgrades

Firmware updates fall into two categories. Distinguishing between them informs how urgently you install them.

Security fix

Addresses a discovered vulnerability. Install promptly — delay means known-bad software is running on your device.

Feature upgrade

Adds support, improves UX or refactors internals. Wait a week or two if you are cautious — early releases occasionally have minor issues that subsequent patches resolve.

How to tell which is which

Release notes label security patches explicitly and usually cite CVE identifiers. Feature notes talk about 'new support' or 'improvements'.

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.
