+ CHANGES IN APE VERSION 2.6-1
+
+
+NEW FEATURES
+
+ o The new speciesTree calculates the species tree from a set of gene
+ trees. Two methods are currently available: maximum tree and
+ shallowest divergence tree.
+
+
+BUG FIXES
+
+ o as.list.DNAbin() did not work correctly with vectors.
+
+ o as.hclust.phylo() failed with trees with node labels (thanks to
+ Filipe Vieira for the fix).
+
+
+
+ CHANGES IN APE VERSION 2.6
+
+
+NEW FEATURES
+
+ o The new functions rlineage and rbdtree simulate phylogenies under
+ any user-defined time-dependent speciation-extinction model. They
+ use continuous time algorithms.
+
+ o The new function drop.fossil removes the extinct species from a
+ phylogeny.
+
+ o The new function bd.time fits a user-defined time-dependent
+ birth-death model. It is a generalization of yule.time() taking
+ extinction into account.
+
+ o The new function MPR does most parsimonious reconstruction of
+ discrete characters.
+
+ o The new function Ftab computes the contingency table of base
+ frequencies from a pair of sequences.
+
+ o There is now an 'as.list' method for the class "DNAbin".
+
+ o dist.dna() can compute the number of transitions or transversions
+ with the option model = "Ts" or model = "Tv", respectively.
+
+ o [node|tip|edge]labels() gain three options with default values to
+ control the aspect of thermometers: horiz = TRUE, width = NULL,
+ and height = NULL.
+
+ o compar.gee() has been improved with the new option 'corStruct' as an
+ alternative to 'phy' to specify the correlation structure, and
+ calculation of the QIC (Pan 2001, Biometrics). The display of the
+ results has also been improved.
+
+ o read.GenBank() has a new option 'gene.names' to return the name of
+ the gene (FALSE by default).
+
+
+BUG FIXES
+
+ o extract.clade() sometimes shuffled the tip labels.
+
+ o plot.phylo(type = "unrooted") did not force asp = 1 (thanks to Klaus
+ Schliep for the fix)
+
+ o dist.dna(model = "logdet") used to divide distances by 4. The
+ documentation has been clarified on the formulae used.
+
+
+OTHER CHANGES
+
+ o rTraitCont(model = "OU") has an option 'linear = TRUE' to possibly
+ change the parameterisation (see ?rTraitCont for details).
+
+ o pic() now returns a vector with the node labels of the tree (if
+ available) as names.
+
+ o write.tree() and read.tree() have been substantially thanks to
+ contributions by Klaus Schliep.
+
+
+
+ CHANGES IN APE VERSION 2.5-3
+
+
+NEW FEATURES
+
+ o The new function mixedFontLabel helps to make labels with bits of
+ text to be plotted in different fonts.
+
+ o There are now replacement operators for [, [[, and $ for the class
+ "multiPhylo" (i.e., TREES[11:20] <- rmtree(10, 100)). They possibly
+ check that the tip labels are the same in all trees.
+
+ o Objects of class "multiPhylo" can be built with c(): there are
+ methods for the classes "phylo" and "multiPhylo".
+
+ o The internal functions .compressTipLabel and .uncompressTipLabel are
+ now documented.
+
+
+BUG FIXES
+
+ o bind.tree(x, y, where, position = 0) did not work correctly if 'y'
+ was a single-edge tree and 'where' was a tip.
+
+ o rTraitCont() did not use the square-root of branch lengths when
+ simulating a Brownian motion model.
