v4.5.6 release

Brightspot 4.5.6 has 10 bug fixes, 16 improvements, and 1 new feature. 

Significant improvements

• Added ability for editors to specify whether changes made to an existing bulk schedule are automatically merged into the schedule or not. If selecting "Do not merge updates," any changes will be live exactly upon publish instead of being held in the schedule for a future publish.
• Improved Post-publish actions UI.
• Added additional handlebars rendering support for Editorial content types. Now, Editorial content types that are configured to extend another Java class or implement an interface will include fields and methods from the superclass, from modifications on the superclass, from modifications on interfaces selected in the JavaScript Class UI, and additionally now display an error message if any methods from an abstract superclass or interface are unimplemented.
  

Significant defects addressed

• Corrected an issue related to refresh times that was at times causing 503 errors.
• Corrected an issue in which the criteria for creating a workstream were not saved with the workstream itself.
• Corrected an issue that caused re-connection to the replicator server to deliver an asset's old revision (the replicator server's cache was not invalidated after re-connection to Brightspot).

Breaking changes

• As a result of improving support for extending superclasses (related to Editorial Content Types and Javascript support), a number of changes were made. Please reference the ticket named BSP-13333 when seeking guidance).
