+  - Special thanks to Jochen Seeber (@jochenseeber):
     - Fix remaining delegation on Ruby 2.7 (PR #62)
+  - Remove support for Ruby 1.8.7 and REE, because they

+  - Announce that continued support for any EOL Ruby versions (that is, versions
+    prior to Ruby 2.5 as of Jan 13 2021) will be decided on **Feb 1, 2021**
+    based on comments to [issue #58](https://github.com/ms-ati/docile/issues/58)
