+@code{IlluminaHumanMethylationEPIC} package.  It utilizes a Manifest based on
+1.0B5 annotation.  As of version 0.3.0, the
+@code{IlluminaHumanMethylationEPIC} package still employs the 1.0B2 annotation
+manifest.  A corresponding annotation package,
+@code{IlluminaHumanMethylationEPICanno.ilm10b5.hg38}, is available to ensure
+proper annotation.  The decision to maintain the same name is due to
+complications in downstream processing caused by array name lookup in certain
+preprocessing options.")
