Wait a minute, the "new codes" are not really new, they were used since long ago. Simply "the old ones" won't work anymore... but as I saw we have still some time, because they are still working on the wiki with version 1.19.

An example of incorrect/correct code is the one I posted, but sometimes it's better check case by case, especially with templates.
