ckb 0.37.0-pre (9ae4b75 2020-10-12)
This is an RC version to preview the changes in the next release.
This version introduces the new RPC doc which contains detailed information about the types and errors.
Breaking Changes
Database
⚠️ This new version will migrate the database on first launch. Please backup the data dir if you want to use old versions later.
⚠️ The migration takes about half an hour. The node denies all RPC requests during the migration.
Config file
There is a new config option db.options_file introduced in #2299. This option provides an options file to tune RocksDB for your workload and your system configuration. More details can be found in the official tuning guide. Remove or comment this option to use the default options file, which is the behavior in previous versions.
RPC
The RPC get_cells_by_lock_hash is deprecated and now it only returns errors (#2269).
There are 4 new RPC methods: ping_peers, get_transaction_proof, verify_transaction_proof, and clear_banned_addresses.
The subscribe RPC added a new topic new_transaction.
