+*** No longer warns about command substitutions by default.
+Checkdoc used to warn about "too many command substitutions" (as in
+"\\[foo-command]"), even if you only used ten of them in a docstring.
+On modern machines, you can have hundreds or thousands of command
+substitutions before it becomes a performance issue, so this warning
+is now disabled by default.  To re-enable this warning, customize the
+user option 'checkdoc-max-keyref-before-warn'.
+
+---
+*** New user option 'checkdoc-column-zero-backslash-before-paren'.
+Checkdoc warns if there is a left parenthesis in column zero of a
+documentation string.  That warning can now be disabled by customizing
+this new user option to nil.  This is useful if you don't expect
+your code to be edited with an Emacs older than version 27.1.
+
+---
+*** Now checks the prompt format for 'yes-or-no-p'.
+In addition to verifying the format of the prompt for 'y-or-n-p',
+checkdoc will now check the format of 'yes-or-no-p'.
+
+---
+*** No longer checks for "A-" modifiers.
+Checkdoc recommends usage of command substitutions ("\\[foo-command]")
+in favor of writing keybindings like "C-c f".  It now no longer warns
+about the "A-" modifier as it is not used very much in practice, and
+this warning therefore mostly led to false positives.
