Version 1.0.0

• Initial Release

Version 1.0.1

• Bugfix for problem with predictions too close to 1 or 0 causing infinite misfit
• Corrected the dependencies for the package

Version 1.1.0

• "connectors" parameter added to LKT which allows controlling component interactions

Version 1.2.0

• Added automatic KC generation using covariance clustering
• "curvefeats" parameter added to allow other inputs for curvilinear effects
• Added HDIntervals (coefficient credibility intervals)

Version 1.3.0

• Updated examples
• Large test sample added
• Bugfix for bug in predict function causing random catastrophic failure

Version 1.5.0

• computeSpacingPredictors speed upgrade using better functions
• buildLKTModel
• LASSOLKTModel
• New examples

Version 1.6.0

• usefolds input to LKT specifies subset of data to fit and precomputed features for test folds are also created for convenience
• restrict LASSOLKT and buildLKTModel by optionally removing component feature pairs that are known to be unjustified

Version 1.7.0

• corrected namespace bug
