1.9.1 (12.02.2024)

This is a patch release that address a bug in Delta during the update of resources:

From 1.9.0 during update operations, Delta does not create a new revision of a resource if no change is detected. When the resource was large or contained too many blank nodes, the complexity increased too much and this could cause CPU starvation.

1.9.0 (18.12.2023)

Breaking changes

Deprecations

  • Fetching resources using organization and project uuids
  • Tagging operations for resolvers/storages/views
  • Indexing projects within views
  • Removing generic endpoints to create/update/deprecate resources
  • Global SSE endpoint
  • SSE endpoints for realms/acls/organizations
  • SSE endpoint to fetch indexing errors
  • Injecting org/project uuids in SSEs related to resources

New features / enhancements

  • Aggregations of resources by @type and project
