-## Liquid Representation
-
-From Jekyll 4.1 onwards, there is a minor change in how instances of `Jekyll::Page` are exposed to layouts and other Liquid
-templates. `Jekyll::Page` instances now use a `Liquid::Drop` instead of a `Hash`. This change results in greater performance
-for a site with numerous *standlone pages not within a collection*.
-
-### For plugin developers
-
-While end-users do not need to take any extra action due to this change, plugin authors depending on the existing behavior *may*
-need to make minor changes to their plugins.
-
-If a `Jekyll::Page` subclass' `to_liquid` method calls `super`, it will have to be slightly modified.
-```ruby
-class Foo::BarPage < Jekyll::Page
-  def to_liquid(*)
-    payload = super        # This needs to be changed to `super.to_h`
-                           # to obtain a Hash as in v4.0.0.
-
-    do_something(payload)  # Logic specific to `Foo::BarPage` objects
-  end
-end
-```
-
-`Jekyll::Page` subclasses won't inherit the optimization automatically until the next major version. However, plugin authors
-can opt-in to the optimization in their subclasses by wrapping the temporary `liquid_drop` method if the subclass doesn't
-override the superclass method:
-```ruby
-class Foo::BarPage < Jekyll::Page
-  def to_liquid(*)
-    liquid_drop    # Returns an instance of `Jekyll::Drops::PageDrop`.
-                   # Will be removed in Jekyll 5.0.
-  end
-end
-```
