+ CHANGES IN APE VERSION 2.6-4
+
+
+NEW FEATURES
+
+ o There is a new image() method for "DNAbin" objects: it plots DNA
+ alignments in a flexible and efficient way.
+
+ o Two new functions as.network.phylo and as.igraph.phylo convert
+ trees of class "phylo" into these respective network classes
+ defined in the packages of the same names.
+
+ o The three new functions clustal, muscle, and tcoffee perform
+ nucleotide sequence alignment by calling the external programs
+ of the same names.
+
+ o base.freq() gains an option 'all' to count all the possible bases
+ including the ambiguous ones (defaults to FALSE).
+
+ o read.nexus() now writes tree names in the NEXUS file if given a
+ list of trees with names.
+
+
+BUG FIXES
+
+ o prop.part() failed in some situations with unrooted trees.
+
+ o read.nexus() shuffled node labels when a TRANSLATE block was
+ present.
+
+ o varCompPhylip() did not work if 'exec' was specified.
+
+ o bind.tree() shuffled node labels when position > 0 and 'where'
+ was not the root.
+
+
+OTHER CHANGES
+
+ o BaseProportion in src/dist_dna.c has been modified.
+
+ o A number of functions in src/tree_build.c have been modified.
+
+ o The matching representation has now only two columns as the third
