Other changes

  • Fixed an issue which caused new information added to fusion.properties to be appended to an existing value instead of creating a new line.

  • Fixed an issue which caused the misspelling, phrase, and synonym detection features to publish corrections which had low confidence scores.

  • Fixed an issue which caused file-extension filtering in the SharePoint connector to be case-sensitive.

  • Fixed an issue which produced a Null Pointer Exception (NPE) error while using SharePoint security trimming on a user with no user groups.

  • Fixed how Cross-Origin Resource Sharing (CORS) is handled when the port is missing from the host/origin headers.

  • Fixed an issue that caused the SmartForm login process in the Web connector to fail.

  • Fixed an issue with the Slack connector that caused only non-public information to appear when security trimming was enabled.

  • Fixed minor issues with the drag-to-reorder feature in the Fusion UI.

  • Fixed an issue that caused the Confluence connector to not create the title field or update the last modified date value.
