You'll notice
Plugin load-failure error messages now mask credential-looking URL segments, not just query strings
What
When a plugin loaded from a URL fails to load, the resulting error message used to only strip out query strings from that URL before showing it. Now a new helper scans the whole message for embedded URLs and also masks any segment that looks like it contains login credentials (matching an @ sign next to quote or bracket characters), in addition to still stripping query strings.
Why
This reduces the chance that a plugin load-failure message accidentally displays a URL containing a username, password, or token.
