        1.

 I updated orgmode package and trying to org-agenda-list, as usual. But failed 
with mistake  — org-agenda-list was empty.
 After investigation, I took advice to put this:

        ;; NB If you want to use this library, it's almost always correct to 
use:
        (eval-when-compile (require 'subr-x))

 in the beginning of .emacs. And it worked. Org-agenda-list was fine.

 The org-agenda-highlight-todo function (org-agenda.el file) uses the
 string-empty-p function from the emacs-lisp/subr-x.el module, but
 somewhere is not done (require ' subr-x), so when calling the
 org-agenda-highlight-todo function, string-empty-p is not defined,
 which leads to an error — org-agenda-highlight-todo: Symbol’s function
 definition is void: string-empty-p

        2.

 For checking I called the emacs -Q and put in it scratch:
        (string-empty-p "test")
        (require 'subr-x)
 Then I executed the command
        C-x C-e
 on
        (require 'subr-x)
 output was
        Debugger entered--Lisp error: (void-function string-empty-p)
        (string-empty-p "test")
        eval((string-empty-p "test") nil)
        elisp--eval-last-sexp(nil)
        eval-last-sexp(nil)
        funcall-interactively(eval-last-sexp nil)
        call-interactively(eval-last-sexp nil nil)
        command-execute(eval-last-sexp)
