<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Updates: Only trigger Background Update processes from within the core update check when a core autoupdate is on offer.
This change reduces the number of API calls which WordPress makes to api.wordpress.org during release windows.
Previously the background updates would run upon every core update transient refresh, however now they'll only run if there's an update available.
The change also increases the cache period for plugin & theme checks when running via the cron, from never-cache to 2 hours, which should hopefully reduce the number of needless API calls.
Fixes <a href="https://core.trac.wordpress.org/ticket/43103">#43103</a> for trunk.</pre>
