3 months ago

EIP-4844 (Data availability) support is added in this release: blobs data is indexed from the consensus layer and can be explorable in the explorer. It is enabled automatically with CHAIN_TYPE=ethereum set in compile and run time.

Polygon ZkEVM bridge operations (transactions/withdrawals) support is added.

In 6.2.0 we continue DB schema enhancements for the sake of improving the performance of the queries. The current release contains denormalization of token_transfers table: block_consensus and token_type fields are added along with background migration to backfill existing data (See the last chapter in 6.0.0 release notes to check the status of background migration). In addition, the performance of the coin balance fetching is improved by exporting it to the asynchronous part of the block import.

More minimal proxy pattern support is added.

It is possible now to link license during verification of the smart-contract.

Fetching of internal transactions from FEVM's (Filecoin EVM) trace_block method is added. And filecoin-related changes are now supported in the master branch of the repo.

⚠️ start_block/end_block filters in API v1 are not supported anymore. Please, use startblock/endblock instead.

⚙️ the release contains 2 foreground migrations for all:

  • extending smart_contracts table with the new column license_type.
  • extending token_transfers table with the new column block_consensus.

And tables creations and extending blocks table for EIP-4844 support (CHAIN_TYPE=ethereum).
Those migrations shouldn't take much time: several minutes at most.
