Description: 

BreadcrumbManager::build() now caches the built breadcrumb in the cache.memory bin. The cache is keyed by route name and raw route parameters. A cached breadcrumb is only reused within the request it was built for.

BreadcrumbManager::__construct() has two new arguments: $memoryCache and $requestStack. Calling the constructor without them is deprecated in drupal:12.1.0. They are required in drupal:13.0.0.

Code that creates BreadcrumbManager directly, or extends it, must pass the new arguments.

Before:

$manager = new BreadcrumbManager($module_handler);

After:

$manager = new BreadcrumbManager(
  $module_handler,
  $container->get('cache.memory'),
  $container->get('request_stack'),
);

Service definitions that extend the breadcrumb service must add the arguments:

arguments: ['@module_handler', '@cache.memory', '@request_stack']
