     CHANGES in PHANGORN VERSION 2.5.4

NEW FEATURES

     o dist.ml, dist.hamming, dist.logDet and dist.p also take DNAbin or

       AAbin objects as input

BUG FIXES

    o bootstrap.pml returned an error with argument optNni=T

      Best practise is to always use TRUE and not T as shortcut

OTHER CHANGES

    o  several more unit tests


     CHANGES in PHANGORN VERSION 2.5.2

NEW FEATURES

     o pratchet, optim.parsimony, optim.pml all may now return trees with

       multifurcations in case duplicated sequences are discovered. This may

       lead to speeding up computations and improved tree topology search.

     o function codonTest which adds codon models to detect positive selection

       (M1a, M2a) and several options to estimate codon frequencies

       (F3x4, F1x4). Can be pretty slow and still experimental.

     o broom type tidy function for several objects to easier compare models

     o new "equal_angle" layout for 2D-networks (now the default)

     o tiplabels, nodelabels, edgelabels from ape work for plot.networx if

       plotted with base R

OTHER CHANGES

     o several small improvements to more intuitively use pml and phyDat

       objects, like subsetting phyDat objects with "[i, j]".

     o several more unit tests

     o two new contributors, Keren and Richel

     o optim.parsimony, pratchet, pmlMix and pmlPart may return the current best

       tree or object when interrupted.

     o roxygen2 is used to generate NAMESPACE file


     CHANGES in PHANGORN VERSION 2.4.0

NEW FEATURES

    o new function add.tips

BUG FIXES

    o midpoint works now for trees with only 2 tips

    o densiTree, bug report by Richel Bilderbeek

    o tree rearrangement in optim.pml return tree with double edge matrix

    o phyDat should work now for named vectors

OTHER CHANGES

    o many more unit tests

    o more consistent coding style

    o flashClust and seqLogo are not suggested packages any more


     CHANGES in PHANGORN VERSION 2.3.0

NEW FEATURES

    o new function mast to compute the maximum agreement subtree

    o identify.networx to identify splits in a network

    o densiTree got more attributes

    o unique.dist, to filter duplicate distances

    o ancestral.pml and ancestral.pars are now may return proper phyDat objects

      and in for DNA may return ambiguous states

BUG FIXES

    o densiTree may if the consensus tree had different ordering of labels

OTHER CHANGES

    o acctran allows multiPhylo objects as input

    o rNNI has been completely rewritten and is faster


     CHANGES in PHANGORN VERSION 2.2.0

NEW FEATURES
