Changes in 6.0:

• Migration from GitHub to NotABug.
• Additional verbosity level, doTrace=3.
• Boruta for those in a hurry vignette.
• Extra-trees importance.

Changes in 5.3:

• Xgboost importance.
• Codebase modernisation.

Changes in 5.2:

• New status messages, including proper grammar and a count of still undecided attributes. (Thanks to Aristide Mooyaart for suggesting this)
• Boruta to formula conversion functions (getConfirmedFormula, getNonRejectedFormula) are back, after a silent disappearance in the 2.0 version. (Thanks to Marco Niemann)
• Documentation fixes.

Changes in 5.1:

• Documentation fix. (Thanks to Andrew Slack-Smith for spotting the problem)
• ranger VIM providers fixed to support survival problems. (Thanks to James Iremonger for spotting this)
• Various documentation updates.
• Code and issues on GitHub.

Changes in 5.0:

• ranger RF implementation replaced randomForest in default importance providers, bringing speed and parallel processing capabilities. Results should be the same, but there may be minor differences. Using getImp=getImpLegacyRfZ restores legacy behaviour. See ?getImpLegacyRf for a further discussion.
• Names of columns in the attStats output changed to reflect the fact that Boruta may use arbitrary importance source.
• Documentation fixes, better organisation of code over files.

Changes in 4.0:

• Initial rounds were dropped from the algorithm, as they seem redundant after implementation of a proper p-value adjustment. This should provide noticeable speed-up, however the results may be different than in previous versions.
• TentativeRoughFix interface changes in order to adapt to the change mentioned above.
• Output of the importance source is validated, so that wrong values will be clearly reported.
• Code clean-up.

Changes in 3.1:

• Better status messages.

Changes in 3.0:

• More importance adapters defined.
• Fixed TentativeRoughFix() bug making this function always return the original Boruta object without any modification.
• Built-in multiple-comparisons correction, which breaks compatibility with older version of Boruta. Use pValue=0.001 and mcAdj=FALSE to trigger the legacy behaviour.
• Experimental, "forced" mode of Boruta dropped. It is equivalent to fixing light argument of Boruta function to TRUE, its previously default value.

Changes in 2.1:

• Fixed attStats() bug making withTentative argument behave opposite to what it should do. (Thanks to Jitao David Zhang for spotting this)

Changes in 2.0:

• Allowed to replace randomForest with other importance source.
• Changes in output; "rand" attributes are now called "shadow" ones.
• ZScoreHistory is now ImpHistory; some scripts and old Boruta objects may become incompatible.
• Documentation updates.
• Formulae export functions become private.

Changes in 1.5:

• Improved performance of dealing with huge inputs.
• Removed redundant decisionHistory from output.

Changes in 1.4:

• Fixed manual entry suggesting that Boruta can only work for classification problems. (Thanks to Allan Engelhardt for spotting this)
• Fixed an error occurring when all attributes are claimed Rejected during one of the initial rounds. (Thanks to Allan Engelhardt for spotting this)

Changes in 1.3:

• Fixes to the output. (Thanks to Achim Zeileis for suggesting them)

Changes in 1.2:

• New plotting function plotZHistory.
• Changes in manual.

Changes in 1.1:

• Fixed a bug making get*Formula functions throw error when Boruta was run with formula provided as a variable.
• Fixed minor documentation inconsistency.

Changes in 1.0:

• First public release.
