This release marks a new major release of lnd that includes several important bug fixes, an improved payment API, pathfinding enhancements, faster initial sync times, support for fee bumping on sweeps, and an initial rollout of altruistic watchtowers. As always, users are highly encouraged to upgrade to this new version.

Database migrations

This version includes two migrations, the first is in channel.db which modifies the structure of the payment tracking data to support the refactored router and its ability to reliably display payments via the RPC. The migration should look like this:

2019-06-14 21:54:53.576 [INF] LTND: Version: 0.7.0-beta commit=v0.7.0-beta-rc1, build=production, logging=default
2019-06-14 21:54:53.579 [INF] LTND: Active chain: Bitcoin (network=mainnet)
2019-06-14 21:54:53.583 [INF] CHDB: Checking for schema update: latest_version=9, db_version=8
2019-06-14 21:54:53.586 [INF] CHDB: Performing database schema migration
2019-06-14 21:54:53.586 [INF] CHDB: Applying migration #9
2019-06-14 21:54:53.586 [INF] CHDB: Migrating outgoing payments to new bucket structure
2019-06-14 21:54:53.586 [INF] CHDB: Migration of outgoing payment bucket structure completed!

The second migration is in wallet.db, which prunes redundant block data already being stored by the underlying backend. The migration should look like this:

2019-06-14 21:54:53.744 [INF] LNWL: Applying wallet address manager migration #8
2019-06-14 21:54:53.746 [INF] LNWL: Removing block hash entries beyond maximum reorg depth of 10000 from current tip 580748

Once updated, it will not be possible to return to an older version of lnd.

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 the keys that have signed this release if you haven't done so already:

curl https://keybase.io/bitconner/pgp_keys.asc | gpg --import

Once you have the required PGP keys, you can verify the release (assuming manifest-v0.7.0-beta.txt and manifest-v0.7.0-beta.txt.sig are in the current directory) with:

gpg --verify manifest-v0.7.0-beta.txt.sig

You should see the following if the verification was successful:

gpg: assuming signed data in 'manifest-v0.7.0-beta-rc1.txt'       
gpg: Signature made Fri Jun 14 14:24:37 2019 PDT                  
gpg:                using RSA key 9C8D61868A7C492003B2744EE7D737B67FA592C7                                                           
gpg: Good signature from "Conner Fromknecht <[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 (which are included in the manifest file):

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 v0.7.0-beta

The binaries are compiled with go1.12.6 and include the following build tags: autopilotrpc, signrpc, walletrpc, chainrpc, invoicesrpc, and routerrpc.

Building the Contained Release

With this new version of lnd, we've modified our release process to ensure the bundled release is now fully self contained. As a result, with only the attached payload with this release, users will be able to rebuild the target release themselves without having to fetch any of the dependencies. Note that at this stage, binaries aren't yet fully reproducible (even with go modules). This is due to the fact that by default, Go will include the full directory path where the binary was built in the binary itself. As a result, unless your file system exactly mirrors the machine used to build the binary, you'll get a different binary, as it includes artifacts from your local file system. This will be fixed in go1.13, and before then we may modify our release system to do this automatically.

In order to re-build from scratch, assuming that vendor.tar.gz and lnd-source-v0.7.0-beta.tar.gz are in the current directory:

tar -xvzf vendor.tar.gz
tar -xvzf lnd-source-v0.7.0-beta.tar.gz
GO111MODULE=on go install -v -mod=vendor -ldflags "-X github.com/lightningnetwork/lnd/build.Commit=v0.7.0-beta" ./cmd/lnd
GO111MODULE=on go install -v -mod=vendor -ldflags "-X github.com/lightningnetwork/lnd/build.Commit=v0.7.0-beta" ./cmd/lncli

The -mod=vendor flag tells the go build command that it doesn't need to fetch the dependencies, and instead, they're all enclosed in the local vendor directory.

Additionally, it's now possible to use the enclosed release.sh script to bundle a release for a specific system like so:

LNDBUILDSYS="linux-arm64 darwin-amd64" ./release.sh
