In the 5.2.1 release, the bundled JVM for the crawler plug-in and customer connector features will be transitioned to IBM Semeru Runtimes, Version 21. If your crawler plug-in or custom connectors used in version 5.2.0 or earlier utilize any features that are incompatible between IBM SDK, Java Technology Edition, Version 8 and IBM Semeru Runtimes, Version 21, you need to revise your code to ensure compatibility with future releases, and re-deploy the built package for version 5.2.1.
{: note}

For JVM migration, see the following pages:

## Knowledge Studio for IBM Cloud Pak for Data deprecation announcement
{: #wks-on-cp4d-deprecation}

After version 4.7, the operator for IBM Knowledge Studio will no longer be supported and will be removed from the IBM Watson Discovery Cartridge for IBM Cloud Pak for Data and from github.com. The service will not be displayed in the Cloud Pak for Data catalog. This change will not impact existing deployments of the operator.

Migrate your solutions to Watson Discovery, which has powerful custom natural language processing capabilities. Any existing Watson Knowledge Studio for Cloud Pak for Data rules-based or machine learning models can be imported to Watson Discovery and applied to your data as custom enrichments. And the recent release of the custom entities extraction feature brings equivalent function to label and train custom entity models into Watson Discovery. For more information about these features, see [Choose enrichments](https://cloud.ibm.com/docs/discovery-data?topic=discovery-data-domain&format=markdown).

For more information about migrating your solutions, see [Migrating Knowledge Studio solutions](https://cloud.ibm.com/docs/discovery-data?topic=discovery-data-migrate-wks&format=markdown).

## 4.0.3 release, 30 November 2021
{: #discovery-data-30november2021}

IBM Watson® Discovery Cartridge for IBM Cloud Pak® for Data 4.0.3 is available.

Another storage option is supported
:   IBM Spectrum Scale Container Native storage is now supported in addition to Red Hat OpenShift Container Storage and Portworx.

Microsoft SharePoint Online data source improvement
:   The *Sharepoint Online* data source now supports crawling your data as a service principal, which means you can access your data without disabling multifactor authentication. For more information, see [Microsoft Sharepoint Online](https://cloud.ibm.com/docs/discovery-data?topic=discovery-data-connector-sharepoint-online-cp4d&format=markdown).

Microsoft Windows File System improvements
:   Extra configuration options mean you can specify the following information:

    -   The types of files (by file extension) to include or exclude from a crawl of a Windows directory.
    -   The character encoding of the data to be crawled. Typically, the encoding is detected automatically. However, you can choose to specify the character encoding as a Java character set yourself.

    For more information, see [Windows File System](https://cloud.ibm.com/docs/discovery-data?topic=discovery-data-connector-wfs-cp4d&format=markdown).

Field selection is improved
:   When you apply an enrichment to a field or choose a field to use as the source for a facet, the fields that are displayed for you to choose from now shows only fields that are valid choices.

Search settings change
:   The spelling correction setting changed from being enabled automatically in new projects to being disabled by default. If you want to alert users when they misspell a term in their query, turn on *Spelling suggestions*. For more information, see [Customizing the search bar](https://cloud.ibm.com/docs/discovery-data?topic=discovery-data-search-bar&format=markdown).

A Salesforce crawling issue was fixed
:   Previously, Discovery had an issue where it timed out before it crawled some of the object types in a Salesforce collection. If your collection is configured to crawl the following object types, run a full data source crawl to make sure that your collection contains the most up-to-date data from all of the objects in your Salesforce data source:

    -   Attachment
    -   ContentVersion
    -   Document

## 4 release, 13 July 2021
{: #release-notes-data-13july2021}

New version now available
:   Discovery for Cloud Pak for Data 4 is available
:   This release is supported on IBM Cloud Pak® for Data 4.0.0.

Change to service name
:   The new name is IBM Watson® Discovery Cartridge for IBM Cloud Pak® for Data.

New Smart Document Understanding (SDU) predefined model
:   When you identify fields, instead of annotating documents with the SDU tool, you can choose to use a pretrained model. The pretrained model applies a non-customizable model that automatically extracts text and identifies tables, lists, and sections.

Improved contract analysis
:   To enable the Contracts enrichment that recognizes and tags contract-related concepts in your data, you can choose to create a Document Retrieval project type, and then select **Apply contracts enrichment**. You no longer need to use an installation override YAML file to enable it. This change also means that you can choose which Document Retrieval projects use the Contracts enrichment; it is not applied to all Document Retrieval projects automatically.

New LDAP directory data source
:   Connect to data that is stored in an external directory that supports the Lightweight Directory Access Protocol (LDAP), such as a corporate email directory. As the directory data is added to your collection, Discovery interprets and stores key attributes of each record, such as department and location information. Later, you can find relevant records by filtering on these attribute categories. For more information, see [LDAP directory](https://cloud.ibm.com/docs/discovery-data?topic=discovery-data-connector-ldap-cp4d&format=markdown).

Improved SharePoint OnPrem connection process
:   The steps you follow to connect to a SharePoint instance that is hosted on-premises were simplified. You no longer need to deploy a web services package on the SharePoint server before you can connect to the SharePoint OnPrem data source. For more information, see [SharePoint OnPrem](https://cloud.ibm.com/docs/discovery-data?topic=discovery-data-connector-sharepoint-onprem-cp4d&format=markdown).

New Salesforce proxy support
:   You can now connect to a Salesforce data source when using a proxy server. For more information, see [Salesforce](https://cloud.ibm.com/docs/discovery-data?topic=discovery-data-connector-salesforce-cp4d&format=markdown).

Improved custom connector improvements
:   Support was added for Optical character recognition (OCR)
:   Support was added for Document-level security

    For more information about the custom connector, see [Building a Cloud Pak for Data custom connector](https://cloud.ibm.com/docs/discovery-data?topic=discovery-data-build-connector&format=markdown).

Change to Dynamic Faceted Search
:   Support for *Dynamic Faceted Search* and its associated `suggested_refinements` API query parameter was removed.

{: #release-notes-data-26february2021}

New release now available
:   IBM Watson™ Discovery for IBM Cloud Pak for Data version 2.2.1 is available.

Support for upgrade
:   Discovery for Cloud Pak for Data supports an in-place upgrade from version 2.2.0 to 2.2.1 so that you do not need to manually uninstall an earlier version and then install the latest version of the service. For more information, see [Upgrading Discovery for Cloud Pak for Data](https://cloud.ibm.com/docs/discovery-data?topic=discovery-data-install&format=markdown#upgrade-discovery).

New SDK download support
:   You can now download the custom connector SDK package from your Discovery for Cloud Pak for Data cluster, instead of retrieving the images and the SDK package from the Docker registry. For more information, see [Downloading the custom-crawler-docs.zip file in Discovery 2.2.1 and later](https://cloud.ibm.com/docs/discovery-data?topic=discovery-data-connector-dev&format=markdown#download-ccs-zip).

:   `Invoices` and `Purchase orders` models can no longer be enabled in the tooling. If you need these models, please contact [IBM Cloud Support](https://cloud.ibm.com/unifiedsupport/supportcenter){: external} to obtain instructions for enabling these models.

Change to Contracts enrichment tables
:   In a `Document Retrieval` project that has the `Contracts` enrichment applied, tables are not included inside the `contracts` field, as they were previously in projects that had the `Contracts` enrichment enabled. Tables will continue to be included in a separate `tables` field when the `Table Understanding` enrichment is applied.

Change to support for Oracle Database 11g and Postgres 9.5
:   Support for connecting to Oracle Database 11g was removed because the vendor ended version support on 31 December 2020.
:   Support for connecting to Postgres 9.5 was removed because the vendor ended version support on 11 February 2021.

New Red Hat OpenShift support
:   Added support for installing IBM Cloud Pak® for Data on Red Hat OpenShift.

Fixed the following defects in Discovery for Cloud Pak for Data offerings purchased on or after August 30, 2019
:   During an active web crawl, if you add an enrichment, then click the **Recrawl collection** button on the **Activity** page, the collection will stop processing. If the collection does not return to a Syncing state on its own, clicking the **Recrawl collection** button an additional time might be required.
:   While training a collection in the tooling , if you rate the relevancy of a result (for example, as`Relevant`), then switch to the opposite rating (`Not relevant`), the page may go blank. To restore the page, refresh the browser. Your updated rating will be retained.
:   Chinese, Japanese, and Korean language Microsoft Word, Excel, and PowerPoint documents will not display correctly in the index or the Smart Document Understanding editor.
:   If you upload a zip, gzip, or tar file to your collection, and that file contains multiple files/file types supported by Smart Document Understanding (PDF, Word, Excel, PowerPoint, PNG, TIFF, JPEG), only one of the files in that zip, gzip, or tar file will be available for training in the SDU editor (unless the SDU document limit has already been met). All of the documents will be available in the index. Unzip the file before uploading to avoid this issue.
:   Query expansion and autocomplete return the wrong error code when the `collection_id` is invalid. Query expansion will return a `500` error code instead of a `404`. Autocomplete will return a `400` when the `collection_id` is invalid and the `prefix` parameter isn’t set. It should also return a `404`.
:   When crawling Microsoft SharePoint 2019 collections, only HTML documents will be crawled and indexed. This is a SharePoint issue with how it processes mime-types. See this Microsoft [blog post](https://blog.stefan-gossner.com/2018/11/30/common-issue-sp2019-items-in-document-libraries-are-downloaded-with-mime-type-application-octet-stream-rather-than-the-accurate-one/) for a workaround.
:   If you delete an installation of the Discovery for Cloud Pak for Data add-on, the instance will not uninstall completely and your re-installation will fail. See the Discovery for Cloud Pak for Data Readme for post-cleanup steps.
:   If a JSON document that contains nested JSON objects is ingested, the nested JSON will be indexed as a JSON string.
