     with its self-documenting `struct ncplane_options` argument. So long as
     the arguments to `ncplane_new()` do not have side-effects, calls can be
     mechanically translated to their `ncplane_create()` equivalents.
-  * A single `struct notcurses` now supports multiple *planepiles* or simply
-    *piles*. Planepiles do not exist as a type (any `ncplane` bound to itself
-    is the root of a pile; the standard plane is always bound to itself, and
-    thus there always exists a *standard pile*), but as a concept. A pile is
-    made up of some root plane, and all planes recursively bound to that root.
-    Multiple threads can freely operate on distinct piles, even rendering them
-    concurrently (into distinct memory, obviously). A pile ceases to exist when
-    all its planes are destroyed, or when its root plane is reparented into
-    another pile. It is an error to call `ncplane_destroy()` on a root plane to
-    which other planes are bound; `ncplane_genocide()` must be employed in this
-    case. It remains impossible to reparent or destroy the standard plane.
-  * A `NULL` `ncplane` can now be passed to `ncplane_create()` as its first
-    argument; the created `ncplane` will root its own new pile. Similarly,
-    `ncplane_reparent()` can now be provided the same `ncplane` for both
-    arguments; the `ncplane` will root its own new pile (unless it already did,
-    in which case this is a no-op). Planes outside the standard pile *are not
-    rendered in a call to `notcurses_render()`*. An `ncplane` can be reparented
-    into any existing pile.
-  * `notcurses_render_pile()` has been added to render a particular pile.
-    `notcurses_render()` now calls `notcurses_render_pile()` with the
-    standard plane.
 
 * 2.0.4 (2020-11-10)
   * Fixed unit tests for non UTF-8 case, brown bagger, alas.
