Changed

  • Compatibility for Node@0.11.3, breaks compatibility with 0.11.2

0.6.1 - 2013-06-15

Fixed

  • Better memory leak fix (@rvagg)

0.4.2 - 2013-05-17

  • Same memory leak fixes as 0.4.1, properly applied to batch() operations too (@rvagg)

0.4.1 - 2013-05-17

Fixed

  • Fix memory leak caused when passing String objects in as keys and values, conversion to Slice created new char[] but wasn't being disposed. Buffers are automatically disposed (reported by @kylegetson levelup/#140) (@rvagg)

0.4.0 - 2013-05-15

Changed

0.3.1 - 2013-05-14

  • Update documentation for .get() (@deanlandolt)

Removed

Historical Note In the early days minor versions were looked upon as major versions. Semver practices we use today was not adopted fully at this time. This is why the history might look a bit confusing.

0.2.4 - 2013-05-21

Historical Note Did not publish as a tag and package.json was never committed with this version number. Most likely due to a locally modified package.json.

0.2.3 - 2013-05-17

Fixed

  • Backport memory leak fixes (@rvagg)

0.2.2 - 2013-05-14

Added

Changed

  • Ignore empty string/buffer start/end options on iterators (@kesla)
  • Macro cleanup, replace some with static inline functions (@rvagg)

Fixed

  • Fix iterator to start on correct value when reverse=true, also handle end-of-store case (#27) (@kesla)

0.2.0 - 2013-03-30

Added

  • Add windows support, using a combination of libuv and Windows-specific code. See README for details about what's required (@rvagg)
  • Add leveldown.destroy(location, cb) to delete an existing LevelDB store, exposes LevelDB.DestroyDB() (@rvagg)
  • Add leveldown.repair(location, cb) to repair an existing LevelDB store, exposes LevelDB.RepairDB() (@rvagg)
  • Add advanced options: writeBufferSize, blockSize, maxOpenFiles, blockRestartInterval, exposes LevelDB options (@rvagg)
  • Add chained batch operations. Argument-less db.batch() will return a new Batch object that can .put() and .del() and then .write(). API in flux so not documented yet. (@juliangruber / @rvagg)

Changed

  • Auto-cleanup iterators that are left open when you close a database; any iterators left open when you close a database instance will kill your process so we now keep track of iterators and auto-close them before a db.close completes (@rvagg)

0.1.4 - 2013-03-11

Changed

0.1.3 - 2013-03-09

Fixed
