Helia v5 has shipped which brings the latest improvements from js-libp2p@2.x.x.
Most of the changes are at the libp2p level so upgrading should be relatively painless depending on how deeply you use the APIs.
Connection management has been tuned to be a lot kinder to low-bandwidth/CPU environments such as React Native, and the DHT has a much less resource intensive routing table. The circuit relay transport is now better at keeping a browser node dialable, and many bits of API cruft have been tidied up.
