  • Fix array-batch memory leak, levelup/#171 (@rvagg)

0.8.3 @ Sept 18 2013

  • Upgrade to [email protected], better support for latest Node master & support for installing within directory structures containing spaces in directory names (@rvagg)

  • Switch to NAN as an npm dependency (@rvagg)

0.7.0 @ Aug 11 2013

  • Added @pgte to contributors list
  • (very) Minor perf improvements in C++ (@mscdex)
  • Use NAN https://github.com/rvagg/nan for Node 0.8->0.11 compatibility

0.6.2 @ Jul 07 2013

  • Compatibility for Node 0.11.3, breaks compatibility with 0.11.2

0.6.1 @ Jun 15 2013

  • Fix broken Windows compile, apply port-uv patch to LevelDB's port.h (@rvagg)

0.6.0 @ Jun 14 2013

0.5.0 @ May 18 2013

  • Bumped major version for db.getProperty() addition (should have been done in 0.4.4) (@rvagg)
  • Disallow batch() operations after a write() (@rvagg)

0.4.4 @ May 18 2013

  • db.getProperty() implemented, see README for details (@rvagg)
  • More work on memory management, including late-creation of Persistent handles (@rvagg)

0.4.3 @ May 18 2013

  • Better memory leak fix (@rvagg)

0.2.2 @ May 17 2013

  • BACKPORT memory leak fixes (@rvagg)

0.4.2 @ May 17 2013

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

0.4.1 @ May 17 2013

  • 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. (@rvagg, reported by @kylegetson levelup/#140)

0.4.0 @ May 15 2013

0.3.1 @ May 14 2013

  • Don't allow empty batch() operations through to LevelDB, on chained of array forms (@rvagg)

0.3.0 (& 0.2.2) @ May 14 2013

  • Pull API tests up into AbstractLevelDOWN, require it to run the tests. AbstractLevelDOWN can now be used to test LevelDOWN-compliant APIs. (@maxogden)
  • Change Iterator methods to return errors on the callbacks rather than throw (@mcollina & @rvagg)

0.2.1 @ Apr 8 2013

  • Start on correct value when reverse=true, also handle end-of-store case #27 (@kesla)
  • Ignore empty string/buffer start/end options on iterators (@kesla)
  • Macro cleanup, replace some with static inline functions (@rvagg)

0.2.0 @ Mar 30 2013

  • Windows support--using a combination of libuv and Windows-specific code. See README for details about what's required (@rvagg)
  • leveldown.destroy(location, callback) to delete an existing LevelDB store, exposes LevelDB.DestroyDB() (@rvagg)
  • leveldown.repair(location, callback) to repair an existing LevelDB store, exposes LevelDB.RepairDB() (@rvagg)
  • advanced options: writeBufferSize, blockSize, maxOpenFiles, blockRestartInterval, exposes LevelDB options (@rvagg)
  • 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)
  • 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.
  • Node 0.11 support (no compile warnings)

0.1.4 @ Mar 11 2013

  • return error when batch ops contain null or undefined (@rvagg / @ralphtheninja / @dominictarr) (additional tests in LevelUP for this)

  • compile error on Mac OS (@kesla / @rvagg)

0.1.0 @ Jan 24 2013

  • change API to export single function levelup() (@rvagg)
  • move createIterator() to levelup#iterator() (@rvagg)
  • make all options arguments optional (@rvagg)
  • argument number & type checking on all methods (@rvagg)
  • stricter checking on key & value types, String/Object.toString()/Buffer, non-zero-length (@rvagg)
  • remove use namespace and add namespace leveldown everywhere (@rvagg)
  • race condition in Iterator end()/next() fix, merged from LevelUP (@ralphtheninja / @rvagg)
  • add complete, independent test suite (@rvagg)

0.0.1 & 0.0.2 @ Jan 2013

  • finalise rename of internal components to LevelDOWN, removing LevelUP references (@rvagg)
