The only reason for a 7.5.10 would be a security issue that would need fixed immediately; of which, none have been reported. As for a release date of 7.6.0, it'll be before any subscriptions end a year from now; we're completely against giving any firm release dates as if it should pass there would be a holy panic like there has been in the past, we don't want any broken promises.
Brooks agreed to 3-4 releases per year, we've released one in 2015; take that as you will.
