Release version 0.26.0 of the Hedera JSON RPC Relay includes a lot of improvements, optimizations and fixes among the most important we want to highlight are parallelization of requests for fetching contract results for each transaction on a block. Removed some unnecessary calls to the mirror node when consuming eth_call, refactor of eth_sendRawTransaction to avoid using the consensus node.
There were also many improvements to the metrics, from new buckets for the histograms that track latency for both the relay and the mirror node request, the fix of the measurement of relay latency and the addition of metrics that capture the functions called on eth_call and eth_sendRawTransaction.
Additionally there were many improvements on the k6 tests that are used to measure performance and load capacity, dapp-test improvements, acceptance tests improvements, documentation improvements, new CI acceptance tests workflows.
At last, on the infrastructure changes there were significant advances on helm charts needed to deploy the web-socket service that will be used by the eth_subscribe method, fixed on the ingress chart
Some bugs were also squashed, in the metrics the label for the methods for measurement of the mirror node latency, a max transaction count for blocks that have too many transactions used on eth_getBlockByHash and eth_getBlockByNumber.
