         CombinatoricsLib - release notes
               by Dmytro Paukov

CombinatoricsLib 2.2 (May 2018)

• Added a method for calculating factorials using BigDecimal (Issue #10).
• Added cartesian product generator.
• Switched to Java 7.
• Changed type of the input parameters for generateObjectsRange() from int to long (Issue #14)
• Factory class renamed to CombinatoricsFactory (Issue #12)

CombinatoricsLib 2.0 (October 2012)

• A new general interface ICombinatoricsVector has been introduced.
  All code has been re-factored to use this interface.
• The permutation generator can produce the permutations even
  if the initial vector has duplicates.
  For example, library can generate all permutations of (1,1,2,2).
• Factory class has been introduced to create all vectors and generators.
• All generators implement the java interface Iterable,
  so they can be used in the "foreach" statement directly.
• Filters have been introduced. All generated vectors can be easily filtered.
• Representation of the combinatorics vectors as strings has been
  changed to format: "CombinatoricsVector=( [elements], size=value)".
• Added the "complex" combination generator called ComplexCombinationGenerator
  and iterator to generate combinations in relation with
  permutations (list partitions).
• Add several methods to detect if a vector contains duplicated elements.
• SubSetGenerator has been updated to support duplicates in the original
  vector which represents the original set. To do that a new iterator
  called "SubListIterator" has been introduced.
• Added a constructor to create a combinatorics vector from an array.
• Added a factory class to make the library more flexible.
