Upgrade Notice
The only notable change from v3.10.3 is the introduction of custom events in the x/signal module. This release targets Mainnet and will be used as the embedded binary in future v4.x.x releases. As a result, node operators do not need to upgrade to this release and are encouraged to upgrade to a v4.x.x release when that is created.
