   * Misc bug fixes
   * There is now a 64-bit windows build built on windows 10
   * Biblatexml datasources now support sourcemapping and have a schema
     automatically generated from the datamodel. See new biber options
     'validate-bltxml' and 'no-bltxml-schema' in --help output.
   * New functionality in sourcemaps for creating new entries and
     looping over specified fields.
   * Sorting key used to sort names is now customisable. See
     \DeclareSortingNamekeyScheme in biblatex manual.
   * Support for Zotero RDF/XML and Endnote removed. These were
     experimental and messy.
