Improvements

Connectors

  • Replaced P12 key with JSON for Google Drive Classic service account.

  • The Connectors API returns the intermediate Deploying and Deleting states to improve the installation and deletion experience. This allows the UI to correctly categorize the displayed connectors list with appropriate state-tags, colors, and labels.

  • V2 connectors index content via key_shared indexing subscriptions. This helps increase indexing performance while maintaining ordering of same document ID updates to Solr.

  • FS connectors have an additional configuration option with Attitiona mounting points to use the FS connector in a cloud environment.

Fusion AI

  • The Query Rewrite ML jobs have a frequency column generated that is shown in the UI. This column should be used to sort in descending order and focus on the high frequency rewrites.

Bug fixes

Fusion

  • In Fusion 5.2, there is no /api/apollo/* API, so the Banana default API settings use /api/* instead.

  • Fixed a bug where foreign characters were skipped during query rewrites.

Connectors

  • Prometheus metrics are integrated with connectors REST, classic, and connector-plugin services.

  • Creating a new datasource fills performance setting parameters with default values for classic connectors.

  • Fixed a bug where config validation failed when provided credentials had S3 bucket access permission but not bucket ownership.

  • Installing from the connector repository installs the latest plugin available.

  • Connectors can now decrypt datasource config after a migration from 5.1.4 to 5.2.0.

Predictive Merchandiser

  • The "Show applied rules" modal works in Details view even when a document is missing signals due to symbol encoding errors.

  • Fixed a bug where facets were not consistently applied to zones.

  • Facets shown in URLs are reapplied on page reload even when cookies are reset.

  • When a user navigates away from unsaved template and zone edits, a confirmation modal is shown.

  • The initial default Home template is renamed as Search Results.

Other changes

  • Before starting a crawl, FTP Pytests checks for a subdirectory and creates the folder if it does not exist.

  • Updated Banana version to banana-fusion@1.6.27.
