==================== Summary ====================

Name: Installer-Core-ul.422
Author: ul
Time: 18 June 2018, 10:43:46.226618 pm
UUID: 418fafe0-8243-4179-b2b3-ca7691208a9b
Ancestors: Installer-Core-ul.421

Do not load MetacelloPreview in Installer class >> #ensureRecentMetacello, because it'll render SqueakSSL unusable by loading an older version of WebClient and SqueakSSL. The method still loads Metacello.
