 # with some changes inspired by Alchemist.Completer (itself based on IEx.Autocomplete).
 # Since then the codebases have diverged as the requirements
 # put on editor and REPL autocomplete are different.
-# However some relevant changes have been merged back
-# from upstream Elixir (1.13).
+# Relevant correctness/feature changes from upstream Elixir have been merged
+# back through v1.20:
+# - cursor parsing is delegated to the host compiler's Code.Fragment
+#   (cursor_context/1, container_cursor_to_quoted/2), so token-level fixes
+#   from the running Elixir apply automatically (e.g. the 1.18+
+#   :block_keyword_or_binary_operator and :capture_arg contexts)
+# - struct expansion crash fixes (elixir-lang/elixir#14308 __MODULE__,
+#   #14150 runtime values)
+# - OTP 28 nominal types
+# IEx-only module-listing memory/prefix-filter optimizations (#15140, #15143)
+# are intentionally NOT adopted: this engine fuzzy-matches module names
+# (ElixirLS.Utils.Matcher) rather than prefix-matching, and caches module
+# results in :persistent_term, so the upstream collection-time prefix filter
+# does not apply.
 # Changes made to the original version include:
 # - different result format with added docs and spec
 # - built in and private funcs are not excluded
