Introducing Arrowhead 6.3.0

Published on: 3 July, 2024

The Rootstock community is pleased to announce the release of the latest version of the RSKj client, which is now available in the RSKj GitHub repository. This update mainly focuses on improving Ethereum compatibility at the JSON-RPC interface and enhancing the node’s performance.

While this upgrade is optional, we strongly encourage users to update their nodes to the most recent version for an enhanced experience and to benefit from the latest improvements.

It’s important to note that this release does not solve the PowPeg issue described in the June 24th Outage Incident Report. The Core Development team is working on a fix that will soon be released.
