 	      NEW FEATURES AND BUG FIXES IN VEGAN 1.17-5				   		    	    
-    
     - anova.cca: Empty models with no constrained component have
       correct degrees of freedom. Tests 'by = "axis"' are really
       marginal for all axes (first axis used to be non-marginal to
       latter axes).
 
     - as.mlm.cca/rda, intersetcor, vif.cca: avoid bug in qr.X in R
-      2.12.0 and older to use wrong variable names in aliased models

     - betadisper: plot did not allow selecting axes. Reported by Sarah
       Goslee. 
 
     - capscale: failed with NA action (reported by Nevil Amos). Total
       inertia is defined as the sum of absolute values of all
-      eigenvalues consistently with cmdscale (from R 2.12.1 but not
-      older) and other vegan functions.

     - decorana: Fortran code prints warnings of failed convergence.
+      Default plot() uses points if items have no name labels to be
+      plotted.
 
+    - deviance.cca/rda: return 0 (instead of NA) for models with no
+      constrained component.
+
     - eigenvals: uses sum of absolute values of eigenvalues in models
       that may have negative eigenvalues (cmdscale, wcmdscale,
       capscale). Can extract eigenvalues of pcnm() and cmdscale() of R

+      2.12.1. Uses zapsmall() to print near-zero
       eigenvalues.
 
+    - mantel.correlog: P-values were slightly off, because function
+      added 1 to the numerator and denumerator, although this
+      correction was already done in mantel(). (The correction was not
+      done in older version of mantel(), but the mantel.correlog() was
+      not changed after fixing mantel()).
+
+    - metaMDS: metaMDSdist() is more verbose about connectivity and
+      handles NA values in dissimiliraties.
+   
     - nestednodf: Gustavo Carvalho's new version that also implements
       a new quantitative method of Almeida-Neto & Ulrich (Env Mod
       Software, in press; 2010).

-      temporarily for the record and consideration:
-
-      o isomap returns only axes related to positive eigenvalues
-      o mantel.correlog tried to fix an order statistic (add +1 to
-        both sides) although this was already fixed in mantel()

-      o CCorA: biplot() resests parameters it sets internally. 
-      o deviance.cca/rda: now zero for models with no constrained

-      o metaMDSdist is more verbose and handles NA values in
