IMPORTANT NOTE: The Trace data are incompatible with v1.1.1 or older versions, and the old data might be incorrect. If you were running a node with executive_trace=true, please clear the data and resync the chain.

Improvements

Configuration Improvements

• Change the default node type to full node instead of archive node. And allow setting the node type in the
  configuration file with the entry node_type.
• Add parameters to independently configure the garbage collection time of different kinds of data (like receipts,
  transactions, block traces, state, e.t.c.). Check the additional_maintained_* entries in run/tethys.toml.
• If block_db_dir or netconf_dir is not set, put the default directory in the one configured with conflux_data_dir.
  The old behavior is to be put in the hard-coded ./blockchain_data.
• Add a parameter public_rpc_apis to control the publicly available RPC interface sets.
  The access to test and debug RPCs is no longer related to mode.
• Remove the parameter enable_tracing because it has been included in the new public_rpc_apis.

RPC Improvements

• Add new local RPC cfx_getEpochReceipts to allow querying receipts based on an epoch number.
• Add new trace RPC trace_filter to allow querying traces based on epochs/types/offset.
• Add new fields latestCheckpoint, latestConfirmed, and latestState in cfx_getStatus.
• Improve some RPC error reporting.

Performance Optimization

• Reduce the memory usage for maintaining more snapshots with the configuration additional_maintained_snapshot_count.

Bug Fixes

• Fix a possible OOM error when a full node is catching up.
• Return correct block_number in cfx_getStatus.
• Fix a bug that makes the configuration mining_author require extra quotes to use a CIP-37 base32 address.
• Fix a bug that the block traces may be incorrect if the pivot chain switches frequently.
