Felix Arntz explains how the Fatal Error Protection feature had to be dropped from WordPress 5.1 due to several security concerns.

Felix also writes about two new proposed web standards, Feature Policy and Reporting API. The Google team has been working on two plugins to bring support for these two new APIs to WordPress.
