lnd v0.9.2-beta
This marks the second minor release in the v0.9.0 series. This release fixes a single bug that affects 32-bit ARM machines. If you run lnd on any other architecture, then you can safely skip this release, and get ready for our upcoming v0.10 release!
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/roasbeef/pgp_keys.asc | gpg --import
Once you have the required PGP keys, you can verify the release (assuming manifest-v0.9.2-beta.txt and manifest-v0.9.2-beta.txt.sig are in the current directory) with:
gpg --verify manifest-v0.9.2-beta.txt.sig
You should see the following if the verification was successful:
gpg: assuming signed data in 'manifest-v0.9.2-beta.txt'
gpg: Signature made Thu Mar 12 17:55:15 2020 PDT
gpg: using RSA key 4AB7F8DA6FAEBB3B70B1F903BC13F65E2DC84465
gpg: Good signature from "Olaoluwa Osuntokun <[email protected]>" [ultimate]
That will verify the signature of the manifest file, which ensures integrity and authenticity of the archive you've downloaded locally containing the binaries. Next, depending on your operating system, you should then re-compute the sha256 hash of the archive with shasum -a 256 <filename>, compare it with the corresponding one in the manifest file, and ensure they match exactly.
Verifying the Release Binaries
Our release binaries are fully reproducible. Third parties are able to verify that the release binaries were produced properly without having to trust the release manager(s). See our reproducible builds guide for how this can be achieved. The release binaries are compiled with go1.13.7, which is required by verifiers to arrive at the same ones. They include the following build tags: autopilotrpc, signrpc, walletrpc, chainrpc, invoicesrpc, routerrpc, and watchtowerrpc. Note that these are already included in the release script, so they do not need to be provided.
Finally, you can also verify the tag itself with the following command:
git verify-tag v0.9.2-beta
Building the Contained Release
Users are able to rebuild the target release themselves without having to fetch any of the dependencies. In order to do so, assuming that vendor.tar.gz and lnd-source-v0.9.2-beta.tar.gz are in the current directory, follow these steps:
tar -xvzf vendor.tar.gz
tar -xvzf lnd-source-v0.9.2-beta.tar.gz
GO111MODULE=on go install -v -mod=vendor -ldflags "-X github.com/lightningnetwork/lnd/build.Commit=v0.9.2-beta" ./cmd/lnd
GO111MODULE=on go install -v -mod=vendor -ldflags "-X github.com/lightningnetwork/lnd/build.Commit=v0.9.2-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" ./build/release/release.sh
⚡️⚡️⚡️ OK, now to the rest of the release notes! ⚡️⚡️⚡️
Release Notes
Bug Fixes
In this release, we update to a new version of x/crypto that drops broken ARM assembly that can cause a segfault in systems like Raspberry Pis. The broken assembly was removed in this commit to the runtime: golang/go@8b77410.
