Stabilised alt_bn128_g1_multiexp, alt_bn128_g1_sum and alt_bn128_pairing_check host functions. This is a protocol change #6813.

Features

Added path option to store configuration which makes location of the RocksDB database customisable via config.json file (at store.path path). #6938
Added single-letter -v, -n and -s switches to localnet command. #6808
Key files can use private_key field instead of secret_key now. This improves interoperability with near cli which uses the former name. #7030
Added Prometheus metrics related to state of the chain, namely: near_balance_burnt, near_blocks_processed, near_chunks_processed, near_final_block_height, near_final_doomslug_block_height, near_gas_price, near_gas_used, near_node_protocol_version and near_total_supply. #6861
Deprecated some Prometheus metrics which performed aggregation in process (rather than leaving it to monitoring system to do) Specifically: near_blocks_per_minute, near_chunk_tgas_used and near_chunks_per_block_millis. #6861
Added network latency measurements. #7050
Rosetta RPC account balance request now accepts public keys in metadata and returns corresponding nonces #7186

Removed testnet alias for localnet command; it’s been deprecated since 1.24 release. (The localnet command itself is still available of course). #7033
Removed unsafe_reset_all and unsafe_reset_data commands; they’ve been deprecated since 1.25 release. #7026
