CHANGES IN VERSION 1.53.1
-------------------------

BUG FIXES

    o Wrapped the Ensembl BioMart queries in the mapToSymbol examples in
      try() so that a temporary outage of the Ensembl service no longer
      aborts 'R CMD check'.

    o Replaced the removed biocLite() calls in the vignette installation
      instructions with BiocManager::install().

OTHER CHANGES

    o Added biocViews terms to DESCRIPTION so that the package is
      categorized on the Bioconductor package index.
