Breaking: #72464 - Removed deprecated code from EXT:workspaces

Description

The following components have been changed during the development of TYPO3 CMS 7 and lead to deprecated code which is removed in TYPO3 CMS 8.

• remove rewritten toolbar item (forge#62800)
• remove rewritten notification parts (forge#35245)

Impact

Using or extending \TYPO3\CMS\Workspaces\ExtDirect\ToolbarMenu will fail since it has been removed.

Using \TYPO3\CMS\Workspaces\Service\StagesService::getNotificationMode($stageId) will fail.

Relying on the following database fields in the tables sys_workspace and sys_workspace_stage will fail:

• sys_workspace.edit_notification_mode
• sys_workspace.publish_notification_mode
• sys_workspace.execute_notification_mode
• sys_workspace_stage.notification_mode

Affected Installations

All installations using workspaces and notifications that have not been migrated to TYPO3 CMS 7, yet.

Migration

First migrate to TYPO3 CMS 7 and use the accordant upgrade wizard (WorkspacesNotificationSettingsUpdate) and then upgrade to TYPO3 CMS 8.
