Rootstock Arrowhead 6.5.0: Optimizing Developer Experience

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 features new debugging methods and other improvements to the JSON-RPC interface, designed to optimize the developer experience.

Although this upgrade is optional, it is strongly recommended that users update their nodes to the latest version to benefit from enhanced performance and security.

What changes are included in RSK Arrowhead 6.5.0?

A non-comprehensive list of changes included in this version follows:

  • Added the debug_traceBlockByNumber RPC method, by @Vovchyk in #2809.
  • Added support for the callTracer trace in the debug_traceTransaction, debug_traceBlockByHash, and debug_traceBlockByNumber RPC methods, by @asoto-iov in #2839.
  • Added support for null values in the to and from input parameters of RPC methods, by @Vovchyk in #2868.
  • Handle reverted transactions in the eth_estimateGas method to align with Ethereum client behavior, by @rmoreliovlabs in #2846.

You can find a complete list of the changes introduced in the corresponding GitHub milestone.

How do I upgrade to version 6.5.0?

Starting with the previous release of RSKj, Java 17 (LTS) has become the minimum supported version, and previous versions of Java will no longer be supported. Node operators upgrading from a version before 6.4.0 should upgrade to a compatible Java version to ensure continued functionality. Upgrading to this version requires no other considerations. 

RSKj Arrowhead 6.5.0’s sha256 sum is 294f99ec76befa7d9ef18eca28d0c884ceb463ce855ef23ddb7a476e551ba191 rskj-core-6.5.0-ARROWHEAD-all.jar. See the reproducible builds guide for further details.
