Changes in 5.0:

• JIM algorithm as an alternative version of JMI which is using Gini impurity instead of information gain.
• Gini impurity feature scorer.
• Fixed instability in breaking ties between equivalent features in multi-threaded case. Now, feature of a lowest index is always returned.

Changes in 4.1:

• Fixed code used to auto-cut numerical values into bins; maximal value used to be wrapped to the minimal bin, which was substantially altering results.

Changes in 4.0:

• MI, CMI, JMI and NJMI feature scorers.
• Parallelism is now controlled by threads argument.
• Documentation improvements.
• Fixed MIM handing of many features with zero score; thanks to smilesun for spotting this.

Changes in 3.0:

• Installation possible without OpenMP support.
• Fixed segfault in NJMIM/JMIM for certain, specific inputs.
• Faster internal hash table.
• Faster CMIM/NJMIM/JMIM due to Fleuret's algorithm.
• New output format.

Changes in 2.0:

• OpenMP parallelism in all praznik functions.
• Fixed segfault for constant numerical features. Thanks to alecuba16 for spotting this.

Changes in 1.0:

• First public release.
