 ### Added
 - [2321](https://github.com/FuelLabs/fuel-core/pull/2321): New metrics for the txpool: "The size of transactions in the txpool" (`txpool_tx_size`), "The time spent by a transaction in the txpool in seconds" (`txpool_tx_time_in_txpool_seconds`), The number of transactions in the txpool (`txpool_number_of_transactions`), "The number of transactions pending verification before entering the txpool" (`txpool_number_of_transactions_pending_verification`), "The number of executable transactions in the txpool" (`txpool_number_of_executable_transactions`), "The time it took to select transactions for inclusion in a block in nanoseconds" (`txpool_select_transaction_time_nanoseconds`), The time it took to insert a transaction in the txpool in milliseconds (`txpool_insert_transaction_time_milliseconds`).
+- [2150](https://github.com/FuelLabs/fuel-core/pull/2150): Upgraded `libp2p` to `0.54.1` and introduced `max_pending_incoming_connections` , `max_established_connections` and `max_pending_outgoing_connections` to limit the number of pending connections.
+
 - [2347](https://github.com/FuelLabs/fuel-core/pull/2364): Add activity concept in order to protect against infinitely increasing DA gas price scenarios
 - [2362](https://github.com/FuelLabs/fuel-core/pull/2362): Added a new request_response protocol version `/fuel/req_res/0.0.2`. In comparison with `/fuel/req/0.0.1`, which returns an empty response when a request cannot be fulfilled, this version returns more meaningful error codes. Nodes still support the version `0.0.1` of the protocol to guarantee backward compatibility with fuel-core nodes. Empty responses received from nodes using the old protocol `/fuel/req/0.0.1` are automatically converted into an error `ProtocolV1EmptyResponse` with error code 0, which is also the only error code implemented. More specific error codes will be added in the future.
 - [2386](https://github.com/FuelLabs/fuel-core/pull/2386): Add a flag to define the maximum number of file descriptors that RocksDB can use. By default it's half of the OS limit.
