v2.0.0-beta

v2.0.0 is a new release with a breaking change in default storage scheme (see below) and some bug fixes and improvements.

Breaking change

v2.0.0 changed its default storage scheme to path-based storage scheme (PBSS) and default db engine to pebble db. Hence, it is incompatible with nodes that was using hash-based storage scheme (HBSS). In order for nodes that have been using HBSS continue to run, the flag state.scheme should be manually set to hash in the cli, or "state.scheme" = "hash" in config.toml.
Same applies for db engine. If the node was using leveldb, in order for nodes continue to use leveldb, the flag db.engine should be manually set to leveldb in the cli, or "db.engine" = "leveldb" in config.toml.
