v2.0.3

Note :

• Requires Go 1.13+

• This version is intended to be the canonical version to be used for the `cosmoshub-3` launch. As a result, no subsequent versions of Gaia will be released until `cosmoshub-3` successfully launches unless necessary due to critical state-machine faults requiring a new version to launch successfully.

Improvements

• (sdk) Bump SDK version to v0.37.4 .

• (tendermint) Bump Tendermint version to v0.32.7 .
