@ -1345,12 +1345,6 @@ via M-n when reading a regexp in the minibuffer.
*** minibuffer-local-must-match-filename-map is now named
minibuffer-local-filename-must-match-map.
---
*** `all-completions' may now return the base size in the last cdr.
Since this means the returned list is not properly nil-terminated, this
is an incompatible change and is thus enabled by the new variable
completion-all-completions-with-base-size.
+++
*** The `require-match' argument to `completing-read' accepts the new
values `confirm-only' and `confirm-after-completion'.
