the output behavior has changed between v1.7 and v1.8:
- v1.7: The output is printed to
stdout
. And output is "mev-boost v1.7"
the version part is same as tag
- v1.8: The output is printed to
stderr
. And output is "mev-boost v1.8.0\n"
the version part is not same as tag
we rely the output to check current version in our script, please use same logic to output the version information thanks
