ncbi-entrez-direct (14.0.20201111+dfsg-1) unstable; urgency=medium

  The main commands for working with NCBI Entrez servers have migrated from
  Perl to shell (backed by curl or wget) by default.  If this change is
  somehow a problem, you can revert to the historical Perl implementations
  by invoking these commands with the -oldmode flag or by setting the
  environment variable USE_NEW_EDIRECT to "0", "off" (case-insensitive),
  "false" (case-insensitive), or "no" (case-insensitive).  (The new
  implementation is expected to work, though.)

  Meanwhile, transmute has a wholly new Go/shell implementation with a
  somewhat different interface.  (The Go portions were originally in
  xtract, which forwards them for now, albeit on an undocumented basis.)
