Breaking changes (3)

  • (v4.2.0) Configuration files with secrets encoded before Linkurious Enterprise v4.0.25 can no longer be decrypted. To avoid any issue, Linkurious must be updated to v4.1 before updating to v4.2.0, so that secrets in configuration files are migrated.
  • (v4.2.0) After this update, users using the embedded Elasticsearch must re-index their data-source.
  • (v4.2.0) If your configuration contains a server.cookieSecret value that is shorter than 64 characters, you must replace it with a longer value.
