New Contributors

The previous binaries attached to this release didn't work with Ubuntu 20.04 LTS, and would give you this error:

/lib/x86_64-linux-gnu/libc.so.6: version GLIBC_2.34 not found

Resolution:

We've updated the Linux/AMD binary in this release with a statically linked one that also works in Ubuntu 20.04 (mev-boost_1.5.0_linux_amd64.tar.gz, sha256: 6356098bdf466cb7907e09a31e9d369a899685f4aa1830f950c2e5ac32b01bec). Re-download from below and all should work!
For ARM, you can find statically linked binaries here
Remember that you can always install mev-boost with go install github.com/flashbots/mev-boost@latest
And you can run mev-boost in Docker too
(see also #473 and #469)

You're probably using the wrong binary for your operating system architecture.
