Do not update to version 4.4 (yet)

Today I’ve update to version 4.4 all my wordpress installation (including this) but I’ve some problem in the comment form (I’ve wrote here https://wordpress.org/support/topic/wp-comments-postphp-return-blank-page-on-44?replies=1 ) Are you having the same problem? I’m waiting for news, or I’ll downgrade to 3.3.1 before the week end
