App maintenance
This reference describes the requirements for submitting updates to a published device app or plugin on Ledger Wallet. Third-party developers are responsible for all updates following the initial release.

Every update must be submitted alongside the following:
| Deliverable | Description |

Submission forms
Updates are submitted via a dedicated form. Only the sections of the app that have changed need to be selected.
| Update type | Form |

| Device app | Device app update form |
| Plugin | Plugin update form |
