Due to the high number of follow-up tickets and associated security concerns, it was decided to reschedule the fatal error recovery feature for WordPress 5.2, in order to address these issues properly. The feature will continue to be developed, with iterations being merged into trunk early in the 5.2 release cycle. Fixes #46141. See #44458, #45932, #45940, #46038, #46047, #46068. Built from https://develop.svn.wordpress.org/trunk@44717 git-svn-id: http://core.svn.wordpress.org/trunk@44548 1a063a9b-81f0-0310-95a4-ce76da25c4cd
