+ o as.hclust.phylo() failed with trees with node labels (thanks to
+ Jinlong Zhang for pointing this bug out).
+
+ o read.dna(, "fasta") failed if sequences were not all of the same
+ length.
+
+ o plot.phylo() did not recycle values of 'font', 'cex' and
+ 'tip.color' correctly when type = "fan" or "radial".
+
+
+OTHER CHANGES
+
+ o In drop.fossil() the default tol = 0 has been raised to 1e-8.
+
+ o The help command ?phylo now points to the man page of read.tree()
+ where this class is described. Similarly, ?matching points to the
+ man page of as.matching().
