 ### Improvements
 
 - (cmd) [\#543](https://github.com/tharsis/evmos/pull/543) Update mainnet default `min-gas-price` to `0.0025aevmos`.
+- (p2p) [\#541](https://github.com/tharsis/evmos/pull/541) Increase default inbound connections and use 8:1 ratio of inbound:outbound. Add default seeds to reduce the need for configuration.
 - (epochs) [\#539](https://github.com/tharsis/evmos/pull/539) Use constants for epoch identifiers.
 - (deps) [\#528](https://github.com/tharsis/evmos/pull/528) Bump Cosmos SDK to [`v0.45.4`](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.45.4)
