+ CHANGES IN APE VERSION 2.7-2
+
+
+NEW FEATURES
+
+ o plot.phylo() has a new option 'draw = TRUE'. If FALSE, the tree
+ is not plotted but the graphical device is set and the
+ coordinates are saved as normal.
+
+
+
+ CHANGES IN APE VERSION 2.7-1
+
+
+NEW FEATURES
+
+ o The new function trex does tree exploration with multiple
+ graphical devices.
+
+ o The new function kronoviz plots several rooted (dated) trees on
+ the scale scale.
+
+ o identify.phylo() has a new option 'quiet' (FALSE by default).
+
+
+BUG FIXES
+
+ o A bug was introduced in read.nexus() in ape 2.7.
+
+ o image.DNAbin() did not colour correctly the bases if there were
+ some '-' and no 'N'.
+
+ o .compressTipLabel() failed with a list with a single tree.
+
+ o identify.phylo() returned a wrong answer when the x- and y-scales
+ are very different.
+
+ o write.nexus() failed with lists of trees with compressed labels.
+
+
+OTHER CHANGES
+
+ o identify.phylo() now returns NULL if the user right-(instead of
+ left-)clicks (an error was returned previously).
+
+ o read.nexus() should be robust to commands inserted in the TREES
+ block.
+
+
+
+ CHANGES IN APE VERSION 2.7
+
+
+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 Four new functions, diversity.contrast.test, mcconwaysims.test,
+ richness.yule.test, and slowinskiguyer.test, implement various
+ tests of diversification shifts using sister-clade comparisons.
+
+ 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
+ column was redundant.
