This version of Lightning Terminal (LiT) ships lnd v0.19.0-beta and tapd v0.6.0-rc2 which comes with full group key support for Taproot Assets Channels!

We'll be continuously working to improve the user experience based on feedback from the community.

Installation and configuration instructions can be found in the README.

This release packages LND v0.19.0-beta, Taproot Assets Daemon v0.6.0-rc2, Loop v0.31.1-beta, Pool v0.6.5-beta and Faraday v0.2.14-alpha.

IMPORTANT NOTE: To avoid loss of funds, it's imperative that you read the Operational Safety Guidelines before before using tapd on mainnet!
The Taproot Assets daemon is still in alpha state, which means there can still be bugs and not all desired data safety and backup mechanisms have been implemented yet. Releasing on mainnet mainly signals that there will be no breaking changes in the future and that assets minted with v0.3.0+ will be compatible with later versions.

Breaking changes (from v0.14.x to v0.15.x)

There are no breaking changes between litd v0.14.1-alpha and v0.15.0-alpha.rc1.
If you are upgrading from an older version than litd v0.14.1-alpha, please carefully read the release notes of litd v0.14.1-alpha.

IMPORTANT NOTE if you ran litd from the master branch at any point and you run into the following error on startup:
ErrTypeForDecoding want (type: *uint8, length: 1), got (type: *uint8, length: 147)

Then you should revert to the version of litd you ran before, and execute the following commands on that old version before updating to this version:

Run lncli querymc > mission_control_backup.json to back up your mission control state.
Run lncli resetmc to clear the mission control state in the database.
Update lnd and lncli to the new version.
(optional) Use lncli loadmc --mcdatapath mission_control_backup.json to restore the backup. Note: This data will not persist across restarts.

Important note for Umbrel/Lightning Terminal users

DO NOT UNDER ANY CIRCUMSTANCE uninstall (or re-install) the "Lightning Terminal" app without first making a manual backup of all local tapd data, if you are using Taproot Assets as part of the "Lightning Terminal" app with Umbrel -- or any comparable node-in-a-box solution. Uninstalling Umbrel apps deletes application data. This Taproot Assets application data encumbers Taproot Assets AND bitcoin funds. Receiving and sending tapd assets updates the daemon's funds-custody material. Merely having the lnd seed phrase is NOT enough to restore assets minted or received. WITHOUT BACKUP BEFORE DELETION, FUNDS ARE DESTROYED.

`lnd` in remote mode (`lnd-mode=remote`)

NOTE that the minimum version of lnd that can be used in --lnd-mode=remote is v0.19.0-beta.

Required changes when running in `lnd` remote mode

When connecting to an existing lnd node, that node must enable the RPC middleware interceptor feature. You can enable that by specifying the --rpcmiddleware.enable command line flag or by adding rpcmiddleware.enable=true to your lnd.conf file. See the remote configuration docs for more information.

NOTE: Taproot Assets Channel functionality is only available when both lnd
and tapd are running in the same process (by setting both
lnd-mode=integrated and taproot-assets-mode=integrated). Remote mode support
will be added in the future.

Verifying the Release

In order to verify the release, you'll need to have gpg or gpg2 installed on your system. Once you've obtained a copy (and hopefully verified that as well), you'll first need to import Oliver Gugger's key from the ubuntu key server:

gpg --keyserver hkps://keyserver.ubuntu.com --recv-keys F4FC70F07310028424EFC20A8E4256593F177720

Once you have his PGP key you can verify the release (assuming manifest-guggero-v0.15.0-alpha.rc1.sig and manifest-v0.15.0-alpha.rc1.txt are in the current directory) with:

gpg --verify manifest-guggero-v0.15.0-alpha.rc1.sig manifest-v0.15.0-alpha.rc1.txt

You should see the following if the verification was successful:

gpg: Signature made Wed 21 May 2025 20:08:47 CET
gpg:                using RSA key F4FC70F07310028424EFC20A8E4256593F177720
gpg: Good signature from "Oliver Gugger <[email protected]>" [ultimate]

That will verify the signature on the main manifest page which ensures integrity and authenticity of the binaries you've downloaded locally. Next, depending on your operating system you should then re-calculate the sha256 sum of the binary, and compare that with the following hashes:

cat manifest-v0.15.0-alpha.rc1.txt

One can use the shasum -a 256 <file name here> tool in order to re-compute the sha256 hash of the target binary for your operating system. The produced hash should be compared with the hashes listed above and they should match exactly.

Finally, you can also verify the tag itself with the following command:

git verify-tag v0.15.0-alpha.rc1
