btcd v0.24.0

This release is a major release that includes several general bug fixes, security bug fixes (please update!), and also a series of performance improvements that dramatically reduce the time for initial block download from ~45 hours+ to around 6 hours! With this release,btcd now also supports BIP 155 and has gained support for pruning (--prune=MiB).

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://raw.githubusercontent.com/lightningnetwork/lnd/master/scripts/keys/roasbeef.asc | gpg --import

Once you have the required PGP keys, you can verify the release (assuming manifest-roasbeef-v0.24.0.sig and manifest-v0.24.0.txt are in the current directory) with:

gpg --verify manifest-roasbeef-v0.24.0.sig manifest-v0.24.0.txt

You should see the following if the verification was successful:

gpg: Signature made Sat Dec 30 17:11:22 2023 PST
gpg:                using RSA key 60A1FA7DA5BFF08BDCBBE7903BBD59E99B280306
gpg: Good signature from "Olaoluwa Osuntokun <laolu32@gmail.com>" [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.
