Historical Note Many commits between 3.1.0 and 4.0.0 are not listed here, because they became irrelevant once we rewrote rocksdb as an N-API addon by importing code from leveldown - essentially starting from scratch. This version of rocksdb includes all relevant changes and bugfixes of (up to and including) leveldown@5.1.0. Please refer to UPGRADING.md for a complete description of breaking changes in the context of rocksdb.
