27.0.91; How to remove Emacs 27 changes to minibuffer? |

NEWS says this:
** Minibuffer
+++
*** A new user option, 'minibuffer-beginning-of-buffer-movement', has
been introduced to allow controlling how the 'M-<' command works in
the minibuffer. If non-nil, point will move to the end of the prompt
(if point is after the end of the prompt).
+++
*** When the minibuffer is active, echo-area messages are displayed at
the end of the minibuffer instead of hiding the minibuffer by the echo
area display. The new user option 'minibuffer-message-clear-timeout'
controls how messages displayed in this situation are removed from the
minibuffer.
---
*** Minibuffer now uses 'minibuffer-message' to display error messages
at the end of the active minibuffer.
+++
*** 'y-or-n-p' now uses the minibuffer to read 'y' or 'n' answer.
---
*** Some commands that previously used 'read-char-choice' now read
a character using the minibuffer by 'read-char-from-minibuffer'.
Emacs 27 is unfortunately _totally_ unusable for me. Cannot do the
slightest thing.
I think that some of the problems come from the changes to minibuffer
and echo-area behavior. Regardless of whether that is the case, I want
to undo those changes. Is there an option for that? (I hope so.) If
not, what changes do I need to make from Lisp, to get back the prior
behavior?

There are a lot of such preprocessing lines in your libraries
(< emacs-major-version 23)
(= emacs-major-version 24)
so you could add something like
(>= emacs-major-version 27)
to handle changes in Emacs 27.
Since NEWS describes how to get back a previous behavior,
I'm closing this report.
