Add a TTL to Core update checks
|Reported by:||dd32||Owned by:||nacin|
Currently WordPress checks for a new version every 12 hours, and once per minute if you're hitting the updates page.
The attached patch introduces a TTL field in the core update response, this allows us to tell an install "Hey, there's an update coming out in the near future, can you please check for an updated version more often?".
The primary use of this would be to alert site administrators to an update as fast as possible, for example, if someone checks their Updates page at 10am, and we release an update at midday, presently they won't get an alert unless they view their updates page again, or visit their site again after 10pm.
