 ### 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]]
