ℹ️ Migration for existing Android legacy wallets (v1.x)

Users upgrading from the legacy Android app (1.x) to 2.x will need to migrate to be able to use 2.x features. See the 2.0.0 release notes for details about the migration process. You can see what version you are currently using in Settings > About.

Changes

Fixed compatibility issue with some BOLT12 offers

See https://github.com/ACINQ/lightning-kmp/pull/686 https://github.com/ACINQ/phoenix/issues/593

Improve Bip353 and Bip21 support

Several issues regarding Bip353 compliance have been fixed, including displaying or copying the ₿ prefix when relevant. When an address is prefixed with ₿ Phoenix will not fallback to LNURL.

Error messages for invalid bip353 addresses have been improved.

Also fixed support for Bip21 URIs containing a lno offer parameter. Behaviour now matches Bip21 URIs containing a lightning parameter (for Bolt11 invoices).

Payer-key behaviour is now set per contact

When creating (or editing) a contact, users can now choose whether a random payer key or their offer key should be used to pay this contact. The global option payer key in Settings > Payment options has been removed.

When paying an unknown offer, Phoenix always uses a random payer key.

Compatibility with Lightning address

Phoenix can still pay LNURL-based lightning addresses. If the user tries to pay an email-like address, Phoenix will first perform a DNS lookup, then if it fails, attempt a LNURL request.
