The 7-dev release provides a major new feature. It gives each block that ability to conditionally display the title link. This is useful if you wish to store a link associated with a block but wish to have the block template render it elsewhere (ex: as an image link). The variable is still stored as $block->title_link.
There is no upgrade path for existing tokens and actions, but there are tokens and actions in Apply for Role 7 that are comparable to the ones that were available in in Apply for Role 6.
