+IMPORTANT! Some of the defaults have changed in Capybara 2.1. If you're experiencing failures,
+please revert to the old behaviour by setting:
+
+    Capybara.configure do |config|
+      config.match = :one
+      config.exact_options = true
+      config.ignore_hidden_elements = true
+      config.visible_text_only = true
+    end
+
+If you're migrating from Capybara 1.x, try:
+
+    Capybara.configure do |config|
+      config.match = :prefer_exact
+      config.ignore_hidden_elements = false
+    end
