This is the 4th minor release in the `v0.10.0-beta-series`. **This release is only relevant for Windows users**. This release includes a bug fix to the recently modified SCB logic to ensure the SCB file is closed before we attempt to rename it. # 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-v0.10.4-beta.txt` and `manifest-v0.10.4-beta.txt.sig` are in the current directory) with: ``` gpg --verify manifest-v0.10.4-beta.txt.sig ``` You should see the following if the verification was successful: ``` gpg: assuming signed data in 'manifest-v0.10.4-beta.txt' gpg: Signature made Tue Jul 14 18:05:39 2020 PDT gpg: using RSA key 4AB7F8DA6FAEBB3B70B1F903BC13F65E2DC84465 gpg: Good signature from "Olaoluwa Osuntokun " [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 `, 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](https://github.com/lightningnetwork/lnd/tree/master/build/release) for how this can be achieved. The release binaries are compiled with `go1.13.12`, 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. The `make release` command can be used to ensure one rebuilds with all the same flags used for the release. If one wishes to build for only a single platform, then `make release sys= tag=` can be used. Finally, you can also verify the _tag_ itself with the following command: ``` git verify-tag v0.10.4-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-v0.10.4-beta.tar.gz` are in the current directory, follow these steps: ``` tar -xvzf vendor.tar.gz tar -xvzf lnd-source-v0.10.4-beta.tar.gz GO111MODULE=on go install -v -mod=vendor -ldflags "-X github.com/lightningnetwork/lnd/build.Commit=v0.10.4-beta" ./cmd/lnd GO111MODULE=on go install -v -mod=vendor -ldflags "-X github.com/lightningnetwork/lnd/build.Commit=v0.10.4-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](https://github.com/lightningnetwork/lnd/pull/2191): ``` make release sys="linux-arm64 darwin-amd64" ``` ⚡️⚡️⚡️ OK, now to the rest of the release notes! ⚡️⚡️⚡️ # Release Notes This release includes a single commit, which is a bug fix for **Windows** related to the modified SCB logic included in `v0.10.4`. On the Windows platform, before a file can be renamed, if it's open, then all handles of the file need to be closed. This latest version now ensures the SCB file is closed before we attempt to rename it.
