Hi Olga,
manualy update is ok, no problem.
The new theme setting is not working well. Live view not show. See:

(my website is on maintenance mode – is in development, but standard WP settings has no problem with maintenance mode)
And that big logo in WP admin is OK? I don’t like it at all, isn’t it a bug? See:
