 * Wed Oct 07 2020 Vít Ondruch <vondruch@redhat.com> - 3.0.0-1
-- Upgrade to Ruby 3.0.0 (6be9d18a4d).
+- Upgrade to Ruby 3.0.0 (1cfc6e7b7a).
 - Extract RSS and REXML into separate subpackages, because they were moved from
   default gems to bundled gems.
 - Obsolete Net::Telnet and XMLRPC packages, because they were dropped from Ruby.
