This allows file operations (such installing extensions or updating the main configuration) without having to make all the folders and files writeable. This makes the site admin's life a lot easier and increases security of the site

You can check the write status of relevent folders by going to ''Help->System Info" and then in the sub-menu to "Directory Permissions". With FTP even if all directories are red, Joomla! will operate smoothly.

NOTE: the FTP layer is not required on a Windows host.

This is now implemented by inserting a tag (button is in the editor area) a dotted line appears in the edited text showing the split location for the "Read more...". A new bot takes care of the rest.

It is worth mentioning that this does not have a negative effect on migrated data from older sites. The new implementation is fully backward compatible.
