+- update to 1.84:
+  * The old parser stores information in a
+    Bio.Blast.NCBIXML.Blast object, with attribute names based on
+    plain-text Blast output. The new parser stores information in
+    a Bio.Blast.Record object. This class follows the DTD that
+    describes the XML in terms of attribute names and dictionary
+    key names, class structure, and object types. This makes it
+    easier to find the detailed description of each field in the
+    NCBI Blast documentation.
+  * The old parser stores alignment information directly as seen
+    in the BLAST XML output, i.e. as strings with dashes to
+    represent gaps. The new parser stores the alignment
+    information as a Bio.Align.Alignment object, which can then
+    be used to e.g. print the alignment in a different format.
