### Backward-incompatible storage format changes

- (Libplanet.RocksDBStore) The blocks and transactions became stored in
multiple databases. Each block and transaction belongs to a partition
of the database, according to its epoch unit, which is its Unix timestamp.
Every epoch is divided by certain seconds, configured by `RocksDBStore()`
constructor's `txEpochUnitSeconds` and `blockEpochUnitSeconds` parameters
(86400 by default). [[#1183], [#1194]]
- (Libplanet.RocksDBStore) Continue on partitioning of database,
`RocksDBStore()` is manage database connection by LRU Cache.
The max size of connection cache is configured by `RocksDBStore()`
constructor's `dbConnectionCacheSize` parameters (100
by default). [[#1183], [#1194]]

### Added APIs

- Added `Block<T>.CurrentProtocolVersion` constant. [[#1142], [#1147]]
