v0.71.0-rc1

v0.70.1

This patch release fixes an issue where synthetic transactions (for example HTS crypto transfers), returned by eth_getTransactionByHash did not include the value field. The value field in transactions is required by the Ethereum JSON-RPC Specification. This release brings us closer to be Ethereum equivalent.

• fix: add value in transaction object for synthetic transactions by @acuarica in #4202

v0.70.0

We are pleased to announce a new JSON-RPC Relay release v0.70.0. This major release introduces a new READ_ONLY mode for the Relay. With this feature, now JSON-RPC Relay operators can run the Relay without transaction capabilities. This can be helpful to use a dedicated Relay for indexing purposes.

Another major feature introduced in this release is gasless transactions. The MAX_GAS_ALLOWANCE_HBAR configuration variable allows operators to pay for user's transactions. With this configuration variable, Relay operators can now decide if they want to subsidized transactions for their users. This provides a seamless process to onboard new users into the network.

This release focuses heavily on Ethereum JSON-RPC Spec compatibility, configuration simplification, and enhanced monitoring capabilities.

Alongside these improvements and refinements, this release includes minor bug fixes, dependency upgrades and internal changes. These updates contribute to a more reliable and seamless developer and user experience.

v0.69.0

Overview

We are pleased to announce a new JSON-RPC Relay release, v0.69.0.Major features include the implementation of LayerZero-based cross-chain bridging for WHBAR and HTS tokens, complete with end-to-end testing and support for custom HTS token transfers. RPC capabilities have been enhanced with support for debug_traceBlockByNumber, better modeling for subscribe controller responses, and declared eth_getProof as unsupported.

Performance was boosted through a more efficient cache layer, Redis-based shared rate limiting, and debug route caching. Dapp examples now include validation for positive amounts and better handling of empty hex proof responses. Several critical fixes were made, including proper handling of malformed RLP data in eth_sendRawTransaction, improved reliability in callTracer, and the resolution of flaky acceptance tests.

v0.69.0-rc1

v0.68.0

We are pleased to announce a new JSON-RPC Relay release v0.68.0. This major release removes the fallback mechanism to Consensus Node for read-only RPC methods. With this improvement, now JSON-RPC Relay operators will only spend HBARs for transactions that modify the network state, making it more economically attractive.

Another important feature of this release is the implementation of Jumbo Transactions. When this feature is enabled on the Consensus Nodes, it will allow users to send Jumbo transactions directly instead of creating a file to send the transaction payload.

Alongside these improvements and refinements, this release includes minor bug fixes, dependency upgrades and internal changes. We have improved the error handling and formatting, so users can have a more informative feedback. These updates contribute to a more reliable and seamless developer and user experience.
