[xgreenx]

Version v0.40.0

Added

• 2347: Add GraphQL complexity histogram to metrics.
• 2350: Added a new CLI flag graphql-number-of-threads to limit the number of threads used by the GraphQL service. The default value is 2, 0 enables the old behavior.
• 2335: Added CLI arguments for configuring GraphQL query costs.

Fixed

• 2345: In PoA increase priority of block creation timer trigger compare to txpool event management

Changed

• 2334: Prepare the GraphQL service for the switching to async methods.
• 2310: New metrics: "The gas prices used in a block" (importer_gas_price_for_block), "The total gas used in a block" (importer_gas_per_block), "The total fee (gwei) paid by transactions in a block" (importer_fee_per_block_gwei), "The total number of transactions in a block" (importer_transactions_per_block), P2P metrics for swarm and protocol.
• 2340: Avoid long heavy tasks in the GraphQL service by splitting work into batches.
• 2341: Updated all pagination queries to work with the async stream instead of the sync iterator.
• 2350: Limited the number of threads used by the GraphQL service.

Breaking

• 2310: The metrics command-line parameter has been replaced with disable-metrics. Metrics are now enabled by default, with the option to disable them entirely or on a per-module basis.
• 2341: The maximum number of processed coins from the coins_to_spend query is limited to max_inputs.
