This release mainly adds features to the JSON RPC.

The finalized tag was added to the RPC methods for retrieving blocks or headers. The resulting blocks are equivalent to latest blocks, since CELO has 1-block finality.
Additionally the eth_getBlockReceipts endpoint has been implemented, providing a more efficient way to receive all block receipts for a block (see ethereum/execution-apis#393)

This release is recommended for users that rely on the eth_getBlockReceipts endpoint or retrieving finalized blocks from the RPC.

• Implement eth_getBlockReceipts (#2284)
