Hello! Recommending that all node operators upgrade the `cometbft` binary to [v0.37.16](https://github.com/cometbft/cometbft/releases/tag/v0.37.16), which includes a security patch relative to the current version.

Heliax has provided some pre-compiled binaries [here](https://github.com/heliaxdev/cometbft/releases/tag/v0.37.16).

The upgrade can be performed async at your earliest convenience. Thank you for your quick action!
