• The Resource Pack version is now 61

Data Pack Version 77

• New optional fields can_be_sheared and shearing_sound have been added to the equippable item component
• Added a way to display very simple dialogs to users
• Added custom - a new click_event action type for text components
• Users will now be prompted for confirmation before executing a command from the run_command click action in books and chat if the command can't be parsed or requires elevated permissions (i.e. higher than 0)

Dialogs

• Added a way to display simple modal dialogs to a user
• Dialogs are stored in a minecraft:dialog registry, but can also be defined inline
• Dialogs are an experimental feature
• To avoid user confusion, dialog screens are marked with a warning sign next to the title
  • Clicking on this warning leads to a dialog that explains to user that this screen is provided by custom content
  • It also gives user an option to leave current world to avoid them being locked in infinite loop of dialogs
• Dialogs can be displayed by server in play and configuration connection phases
  • However, only inline registries are allowed in configuration, since registries are not yet available in that phase
• Dialogs always close after user selects any action
• Dialogs by default will also close after Escape key is pressed
  • When this happens, dialog will run action specific to dialog type described as "exit action" below
  • This behavior is configurable
• When dialog screen is closed, game goes back to previously displayed non-dialog screen or back to gameplay
  • That means that new dialogs always replace already opened ones, if any
• Dialogs screens will pause the game in singleplayer mode
• Dialogs can be configured to be accessible from Pause menu
  • This replaces and expands "Server Links" button added in previous versions
• Most dialogs follow a common layout, however exact contents depend on type:
  • Header with title and warning button
  • Body elements (labels, inputs, buttons and submit actions), scrollable if needed
  • Optional footer, contains main buttons and submit actions

Developer's Note: Dialogs are not supposed to fully describe any in-game UI, but just to allow custom content to display simple messages and get input from users. This feature is intentionally limited to match that use case.
