It’s not inherently more or less secure than any other properly implemented escaping routine. It is closer to specifics of WP and configuration it is aware off.
Keeps asking Connection Information upon update to 3.5.1 (but not for plugins?)
WordPress primary choice is to do upgrade using direct file IO. So if it’s asking you for FTP credentials it means that it has no access to these files. The easiest way to fix this will be changing file permissions so WordPress could modify them. Of course if you changed those permissions to improve security … Read more
