v0.67.0

Overview

We are pleased to announce a new JSON-RPC Relay release, v0.67.0, the first release under the Hiero organization. This is one step closer to ensure the project is properly governed and its lifespan is driven by the community.

This major update now includes support for eth_getBlockReceipts RPC method. This method is part of the Ethereum JSON-RPC specification. With the inclusion of eth_getBlockReceipts we get one step closer to be Ethereum equivalent. Another major feature as part of this release is the addition of the /config route. This allows JSON-RPC Relay users to get the configuration of the running Relay. For example, you can retrieve the URL of the Mirror Node backend with this feature.

Alongside these improvements and refinements, this release includes minor bug fixes, dependency upgrades and internal changes like enhanced Grafana dashboard visibility for Ethereum RPC execution methods. It also introduces the USE_MIRROR_NODE_MODULARIZED_SERVICES configuration flag which enables Is-Modularized queries to the Mirror Node (empty by default). See #3626 for more details. These updates contribute to a more reliable and seamless developer experience.
