## July 2026
{: #watson-knowledge-studio-july26}
{: release-note}

Migrate from IBM Watson Knowledge Studio to watsonx.ai
:    IBM Watson Knowledge Studio is deprecated. Existing customers must migrate their workloads before the service is removed from IBM Cloud on 31 January 2028. The migration documentation includes the service withdrawal timeline and the guidance for using watsonx.ai Prmopt Lab for prompt engineering and watsonx.ai Tuning Studio for prompt tuning with IBM Granite foundation models. See [Migrating from Watson Knowledge Studio to watsonx.ai Studio with Watson NLP](https://cloud.ibm.com/docs/watson-knowledge-studio?topic=watson-knowledge-studio-migrating-from-watson-knowledge-studio-to-watsonxai-studio-with-watson-nlp&format=markdown).

## May 2025
{: #watson-knowledge-studio-may25}
{: release-note}

Rules editor will be ending on 30 June 2025.
:    The rules editor feature will end on 30 June 2025. Existing rules can be edited and exported until that time. Rules models that are deployed on your IBM Watson&reg; Natural Language Understanding instances can continue to run after that date. Rules models that are exported can also continue to run in IBM Watson&reg; Discovery after that date.

    After 30 June 2025, you can use IBM watsonx.ai for [detecting entities with a custom dictionary](https://www.ibm.com/docs/en/watsonx/saas?topic=models-detecting-entities-custom-dictionary){: external} and [regular expressions](https://www.ibm.com/docs/en/watsonx/saas?topic=models-detecting-entities-regular-expressions){: external}.

Dictionary suggestions on the editor UI will be ending on 30 June 2025.
:    The dictionary suggestions on the dictionary editor UI will be ending on 30 June 2025. After 30 June 2025, you can still edit dictionaries, but the entry suggestions panel is not available after that date.

## May 2022
{: #watson-knowledge-studio-may22}
{: release-note}

Advanced Rules Editor (Beta) will be ending on 30 June 2022.
:   The Advanced Rules Editor (ARE) (Beta) feature will end on 30 June 2022. Existing rules created in ARE workspaces can be edited and exported until that time. Any rules models that are exported can continue to be run in IBM Watson&reg; Discovery or IBM Datacap after that date.

    After 30 June 2022, Rules models can be created using the Knowledge Studio [Rules annotator](https://cloud.ibm.com/docs/watson-knowledge-studio?topic=watson-knowledge-studio-rule-annotator&format=markdown). You may also use Discovery; the creation of rules is provided by teaching Discovery to [recognize patterns in your data](https://cloud.ibm.com/docs/discovery-data?topic=discovery-data-domain&format=markdown#patterns).

## March 2020
{: #watson-knowledge-studio-mar20}
{: release-note}

Enhanced pre-annotation workflow
:   Run multiple pre-annotators at once and configure the order of pre-annotators to resolve annotation conflicts between them. Existing pre-annotator results are preserved unless you remove them with the *Wipe* option.
:   Human annotations are preserved when running pre-annotators, even when using the *Wipe* option.

## December 2019
{: #watson-knowledge-studio-dec19}
{: release-note}

### New features and changes
{: #new-december-2019}

New advanced rules tokenizer
:   Advanced rules has introduced a new tokenizer which is not compatible with the previous one. The following extractor categories are affected:

    - **Parts of Speech** extractor names are renamed automatically
        - **Cardinal** is renamed to **Numeral**
        - **Preposition** is renamed to **Adposition**
    - **Machine Data Analytics** Splitter extractors have been removed and will disappear from the canvas. There is no substitute for these extractors that is provided by the new tokenizer.
        - Generic Splitters:
            - **Date Time Splitter**
            - **Day First Splitter**
            - **Month First Splitter**
            - **Year First Splitter**
        - Syslog Splitter:
            - **Date Time Splitter**
:   Cross-sentence relations (Experimental)

    - English entities and relations workspaces can now support annotating relations between entities within spans of six sentences. To get started, see [Enabling cross-sentence relations](https://cloud.ibm.com/docs/watson-knowledge-studio?topic=watson-knowledge-studio-enabling-cross-sentence-relations&format=markdown).

:   Full support for IBM Cloud IAM

    - Knowledge Studio now supports the full implementation of IBM Cloud Identity and Access Management (IAM). API keys for Watson services are no longer limited to a single service instance. You can create access policies and API keys that apply to more than one service, and you can grant access between services.
    - For more information about IAM, see [Authenticating to Watson services](https://cloud.ibm.com/docs/watson?topic=watson-iam&format=markdown).
    - To support this change, the API service endpoints use a different domain and include the service instance ID. The pattern is `api.{location}.{offering}.watson.cloud.ibm.com/instances/{instance_id}`.

        The previous public endpoint domain was `watsonplatform.net`.

        These URLs do not introduce a breaking change. The new URLs work both for your existing service instances and for new instances. The original URLs continue to work on your existing service instances for at least one year (until December 2020).

| Region | Old | New |
|--|--|--|
| Dallas | `gateway.watsonplatform.net` | `us-south.knowledge-studio.watson.cloud.ibm.com` |

    - Users of new premium and dedicated instances can integrate IBM&reg; Key Protect for IBM Cloud&reg; with Knowledge Studio to encrypt their data and manage encryption keys. For more information, see [Protecting sensitive information in your Watson service](https://cloud.ibm.com/docs/watson?topic=watson-keyservice&format=markdown).
    - **Support for private network endpoints**
        - Users of Premium plans can create private network endpoints to connect to Knowledge Studio over a private network. Connections to private network endpoints do not require public internet access. For more information, see [Public and private network endpoints](https://cloud.ibm.com/docs/watson?topic=watson-public-private-endpoints&format=markdown).

## July 2018
{: #watson-knowledge-studio-jul18}
{: release-note}

### New features and changes
{: #new-jul18}
{: release-note}

Deployed Models page updated
:   The **Deployed Models** page was updated to include models from Knowledge Studio instances that are managed by [IAM *resource groups*](https://cloud.ibm.com/docs/iam?topic=iam-userroles&format=markdown){: external}, in addition to models that are managed by [Cloud Foundry *organizations*](https://cloud.ibm.com/docs/iam?topic=iam-cfaccess&format=markdown){: external}.

    What you see on the Deployed Models page depends on the [region](https://cloud.ibm.com/docs/resources?topic=resources-services_region&format=markdown){: external} that hosts your Knowledge Studio instance. If the region supports instances managed by both access management methods, you see a tab for each method. Models from instances that are managed by IAM are listed on the **Resource Groups** tab. Models from instances that are managed by Cloud Foundry are listed on the **Organizations** tab.

    If the region supports instances managed by only one of the access management methods, you see only one list of models, because only one access management method is applicable.

    To view the **Deployed Models** page, from the **Settings** menu in the top right menu bar, click **Manage deployed models**. For more information about undeploying models on the **Deployed Models** page, see [Undeploying machine learning models](https://cloud.ibm.com/docs/watson-knowledge-studio?topic=watson-knowledge-studio-publish-ml&format=markdown#pm-um) and [Undeploying rule-based models](https://cloud.ibm.com//docs/watson-knowledge-studio?topic=watson-knowledge-studio-wks_rule_publish).

Navigation changed to better align with the Knowledge Studio workflow.
:   In addition, the following functionality was reorganized:

    - In the previous version, management of dictionaries was included as part of the Pre-annotators page. Now, management of dictionaries is located on the Dictionaries page in the Assets section of the navigation.
    - In the previous version, human annotation functionality was distributed across the Mentions, Relations, and Coreferences tabs in the Document Annotation section of the navigation. Now, the functionality is merged under the Annotation Tasks page in the Machine Learning Model section of the navigation.
    - To manage human annotation tasks, in the previous version, you found the Tasks tab under the Assets & Tools > Documents page. Now, you add tasks and manage existing tasks on the Annotation Tasks page in the Machine Learning Model section of the navigation.
    - In the previous version, the Rules, Regex and Dictionaries pages were separate pages in the Document Annotation section of the navigation. Now, the functionality is merged under the Rules page in the Rule-based Model section of the navigation.

    For more details about the navigation changes, see Figure 1 and Table 3.
