What I'd like to suggest is to move the target release dates to early May and November. Or would this create a conflict with any holiday season we care about? In order not to have a very short release cycle for 4.11 I'd do the shift in two steps (so 4.11 target release date mid of May, 4.12 early November). What do you think?
