jruby (9.2.17.0-1) unstable; urgency=medium

  Since jruby 9.2.17 only targets ruby2.5 compatbility and since Debian now
  packages ruby2.7-compatible gems, support for loading ruby libraries from
  /usr/lib/ruby/vendor_ruby has been removed from this version of jruby.
  .
  This change might introduce breakage if you depended on this feature. See
  BTS #977981 for more details.
