• Add additional arguments to the function that downloads and loads the
  krebsregister data. The argument missing_values is used to fill missing
  values. Default: nothing is done. The argument shuffle is used to
  shuffle the records. Default is True.
• Remove the lastest traces of the old package name. The new package name is
  'Python Record Linkage Toolkit'
• Better error messages when there are only matches or non-matches are passed
  to train the classifier.
• Add AirSpeedVelocity tests to test the performance.
• Compare for deduplication fixed. It was broken.
• Parameterized tests for the Compare class and its algorithms. Making use
  of nose-parameterized module.
• Update documentation about contributing.
• Bugfix/improvement when blocking on multiple columns with missing values.
• Fix bug #29. Package
  not working with pandas 0.18 and 0.17. Dropped support pandas 0.17 and fixed
  support for 0.18. Also added multi-dendency tests for TravisCI.
• Support for dedicated deduplication algorithms
• Special algorithm for full index in case of finding duplicates. Performce is
  100x better.
• Function max_number_of_pairs to get the maximum number of pairs.
• low_memory for compare class.
• Improved performance in case of comparing a large number of record pairs.
• New documentation about custom algorithms
• New documentation about the use of classifiers.
• Possible to compare arrays and series directly without using labels.
• Make a dataframe with random comparison vectors with the
  binary_comparisons in the recordlinkage.datasets.random module.
• Set KMeans cluster centers by hand.
• Various documentation updates and improvements.
• Jellyfish is now a required dependency. Fixes bug #30.
• Added tox.ini to test packaging and installation of package.
• Drop requirements.txt file.
• Many small fixes and changes. Most of the changes cover the Compare
  module. Especially label handling is improved.
