WordPress Performance Trac tickets

  • @westonruter shared that prefetching has finally been committed in changeset 64120. The next step is to default script and style concatenation to off outside development environments in PR #13090. After that, the plan is to remove load-scripts.php and load-styles.php, along with the concatenation and compression logic that has been problematic for many years.
