-Various completion features have been simplified. The options
-@code{completion-cycle-threshold} and
-@code{completion-category-overrides} have been removed. Due to the
-latter removal, Emacs uses a single consistent scheme to generate
-completions, instead of using a separate scheme for (say) buffer name
-completion. Several major modes, such as Shell mode, now implement
-their own inline completion commands instead of using
-@code{completion-at-point}.
