+## Ruby 2.7 compatibility
+
+* Shrine doesn't trigger [Ruby 2.7 warnings for separation of positional and
+  keyword arguments][kwargs] anymore.
+
+* Down 5.1.0 has been released, which resolves warnings and a `FrozenError`
+  exception on Ruby 2.7. Shrine now requires at least this version of Down.
+
+  If you're using `Down::Http`, make sure you're using http.rb 4.3.0 or newer.
+
+* ImageProcessing 1.10.3 gem has been released which resolves Ruby 2.7 warnings
+  as well. If you're using it for image processing, make sure to upgrade to
+  this version:
+
+  ```rb
+  gem "image_processing", ">= 1.10.3", "< 2"
+  ```
+
+## Rack 2.1.0 compatibility
+
+* The `derivation_endpoint` plugin now uses `Rack::Files` on Rack 2.1.0 or
+  newer.
+
+## Other improvements 
+
+* The `S3#open` method now handles empty S3 objects.
