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

Users upgrading from the legacy 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

Use taproot addresses by default, and rotate addresses

The address displayed by Phoenix for on-chain to Lightning swaps is now a Taproot address. This address is not static anymore. Phoenix will generate a new swap-in address upon receiving a transaction. This improves privacy, and also makes deposits cheaper.

See our blog post for more information: http://acinq.co/blog/phoenix-swaproot

Already used address are listed in Settings > Wallet info > Swap-in addresses.

If need be, users can switch back to the static, native segwit legacy address in Settings > Payment options (on Android) or Receive > on-chain > Edit (on iOS).

Support for quiescence

Phoenix can now splice (in/out) a channel while a Lightning payment is in-progress.

See https://github.com/ACINQ/lightning-kmp/pull/568 and https://github.com/ACINQ/eclair/commit/47e0b834383ad7dcdb280c07cbf75bf486e06ee7 for details.

Upgrade of internal tools

This is not visible to the users but the app (and all the lightning/bitcoin dependency suite) has been upgraded to kotlin 1.9, and a new logging framework.
