Description: 

YAML files for contextual links, local tasks, and local actions have been renamed to improve the developer experience. The new naming scheme makes it easier for a developer to determine what a module implements, and does not require module developers to know special names for each subsystem.

Also, the the naming is more consistent and as an added bonus makes the files appear grouped together in a directory listing.

  • *.local_tasks.yml has been renamed to *.links.task.yml
  • *.local_actions.yml has been renamed to *.links.action.yml
  • *.contextual_links.yml has been renamed to *.links.contextual.yml
  • *.menu_links.yml has been renamed to *.links.menu.yml
