There shouldn't be a difference between master and release branch. Can
you please check lisp/net/tramp-loaddefs.el? There should be something like

--8<---------------cut here---------------start------------->8---
(tramp--with-startup (add-to-list 'tramp-methods `(,tramp-sshfs-method 
(tramp-mount-args (("-C") ("-p" "%p") ("-o" "idmap=user,reconnect"))) 
(tramp-login-program "ssh") (tramp-login-args (("-q") ("-l" "%u") ("-p" "%p") 
("-e" "none") ("%h") ("%l"))) (tramp-direct-async t) (tramp-remote-shell 
,tramp-default-remote-shell) (tramp-remote-shell-login ("-l")) 
(tramp-remote-shell-args ("-c")))) (add-to-list 'tramp-connection-properties 
`(,(format "/%s:" tramp-sshfs-method) "direct-async-process" t)) 
(tramp-set-completion-function tramp-sshfs-method 
tramp-completion-function-alist-ssh))
--8<---------------cut here---------------end--------------->8---

Perhaps you regenerate this file? Try

--8<---------------cut here---------------start------------->8---
$ rm lisp/net/tramp-loaddefs.el
$ make -C lisp autoloads
--8<---------------cut here---------------end--------------->8---

Best regards, Michael.
