0.3.4

• Previously the Reader would hold onto the underlying file and FileChannel,
  not closing them until the Reader was closed. This was unnecessary; they
  are now closed immediately after they are used. Fix by Andrew Snare; GitHub
  issue #7.
• The Reader now discards the reference to the underlying buffer when
  close() is called. This is done to help ensure that the buffer is garbage
  collected sooner, which may mitigate file locking issues that some users
  have experienced on Windows when updating the database. Patch by Andrew
  Snare; GitHub issue #8.
