Release version v0.28.0 of the Hedera JSON RPC Relay includes enhancements, such as support for synthetic transactions (transfers of HTS tokens), improved assessment of the cost of the getContractByteCode operation, web-sockets and eth_subscribe capability, a correct message for CONTRACT_REVERT, and Remix IDE support.
Additionally, there are important performance improvements, including httpAgent keepAlive configuration by default, an increased number of sockets for outgoing connections, and a cacheable DNS lookup resolver for outgoing requests. The eth_getTransactionCount function has also been refactored and optimized.
Finally, the release includes cleanup of test cases, pnpm dependencies, improved logging across classes, and documentation.
