## Upgrade notes

- **Electrum plugin 0.4.2.** It works in the Electrum binaries and talks to 0.4.1 peers. No action needed.
- **Electrum plugin 0.4.1.** Pools created by 0.4.0 cannot be joined from 0.4.1. Finish or abandon them before upgrading.
- **Android 0.2.0 and later.** The signing certificate changed in 0.2.0. Uninstall 0.1.x before installing a newer version.
