  * Fixed fuzzy matching when updating message catalogs (ticket #82).

    from different catalogs based on the same template.
  * Location lines in PO files do no longer get wrapped at hyphens in file
    names (ticket #79).
+ * Fixed division by zero error in catalog compilation on empty catalogs
+   (ticket #60).
