 Apply the following changes to code written against Amaranth 0.4 to migrate it to version 0.5:
 
+* Update uses of :py:`reset=` keyword argument to :py:`init=`.
+* Ensure all elaboratables are subclasses of :class:`Elaboratable`.
 * Replace uses of :py:`m.Case()` with no patterns with :py:`m.Default()`.
 * Replace uses of :py:`Value.matches()` with no patterns with :py:`Const(1)`.
-* Update uses of :py:`amaranth.utils.log2_int(need_pow2=False)` to :func:`amaranth.utils.ceil_log2`.
-* Update uses of :py:`amaranth.utils.log2_int(need_pow2=True)` to :func:`amaranth.utils.exact_log2`.
-* Update uses of :py:`reset=` keyword argument to :py:`init=`.
-* Convert uses of :py:`Simulator.add_sync_process` used as testbenches to :meth:`Simulator.add_testbench <amaranth.sim.Simulator.add_testbench>`.
-* Convert other uses of :py:`Simulator.add_sync_process` to :meth:`Simulator.add_process <amaranth.sim.Simulator.add_process>`.
-* Convert simulator processes and testbenches to use the new async API.
-* Replace uses of :py:`amaranth.hdl.Memory` with :class:`amaranth.lib.memory.Memory`.
+* Ensure clock domains aren't used outside the module that defines them, or its submodules; move clock domain definitions upwards in the hierarchy as necessary
 * Replace imports of :py:`amaranth.asserts.Assert`, :py:`Assume`, and :py:`Cover` with imports from :py:`amaranth.hdl`.
 * Remove uses of :py:`name=` keyword argument of :py:`Assert`, :py:`Assume`, and :py:`Cover`; a message can be used instead.
-* Ensure all elaboratables are subclasses of :class:`Elaboratable`.
-* Ensure clock domains aren't used outside the module that defines them, or its submodules; move clock domain definitions upwards in the hierarchy as necessary
-* Remove uses of :py:`amaranth.lib.coding.*` by inlining or copying the implementation of the modules.
+* Replace uses of :py:`amaranth.hdl.Memory` with :class:`amaranth.lib.memory.Memory`.
 * Update uses of :py:`platform.request` to pass :py:`dir="-"` and use :mod:`amaranth.lib.io` buffers.
+* Remove uses of :py:`amaranth.lib.coding.*` by inlining or copying the implementation of the modules.
+* Convert uses of :py:`Simulator.add_sync_process` used as testbenches to :meth:`Simulator.add_testbench <amaranth.sim.Simulator.add_testbench>`.
+* Convert other uses of :py:`Simulator.add_sync_process` to :meth:`Simulator.add_process <amaranth.sim.Simulator.add_process>`.
+* Convert simulator processes and testbenches to use the new async API.
 * Update uses of :meth:`Simulator.add_clock <amaranth.sim.Simulator.add_clock>` with explicit :py:`phase` to take into account simulator no longer adding implicit :py:`period / 2`. (Previously, :meth:`Simulator.add_clock <amaranth.sim.Simulator.add_clock>` was documented to first toggle the clock at the time :py:`phase`, but actually first toggled the clock at :py:`period / 2 + phase`.)
 * Update uses of :meth:`Simulator.run_until <amaranth.sim.Simulator.run_until>` to remove the :py:`run_passive=True` argument. If the code uses :py:`run_passive=False`, ensure it still works with the new behavior.
+* Update uses of :py:`amaranth.utils.log2_int(need_pow2=False)` to :func:`amaranth.utils.ceil_log2`.
+* Update uses of :py:`amaranth.utils.log2_int(need_pow2=True)` to :func:`amaranth.utils.exact_log2`.

 The :mod:`amaranth.lib` module, also known as the standard library, provides modules that falls into one of the three categories:
 
-1. Modules that will used by essentially all idiomatic Amaranth code, or which are necessary for interoperability. This includes :mod:`amaranth.lib.enum` (enumerations), :mod:`amaranth.lib.data` (data structures), :mod:`amaranth.lib.wiring` (interfaces and components), and :mod:`amaranth.lib.meta` (interface metadata).

 As part of the Amaranth backwards compatibility guarantee, any behaviors described in these documents will not change from a version to another without at least one version including a warning about the impending change. Any nontrivial change to these behaviors must also go through the public review as a part of the `Amaranth Request for Comments process <https://amaranth-lang.org/rfcs/>`_.
