-Subject: [PATCH] config: support .include directive
-
-OpenSSL 1.1.1 introduces a new '.include' directive. Update our config
-parser to support that.
-
-As mentioned in the referenced GitHub issue, we should use the OpenSSL
-API instead of implementing the parsing logic ourselves, but it will
-need backwards-incompatible changes which we can't backport to stable
-versions. So continue to use the Ruby implementation for now.

 * Mon Feb 24 2020 Vít Ondruch <vondruch@redhat.com> - 2.8.0-1
-- Upgrade to Ruby 2.8.0 (83705c42ce).
+- Upgrade to Ruby 2.8.0 (810d66f3e7).
 - 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.
