Knowledge Discovery 26.1.0
26.1 Release Notes

# View Component

View Component is an ACI server. For details of changes that affect all ACI servers, see ACI Server Framework.

## 26.1.0

There were no new features or resolved issues in this release.

## 25.4.0

There were no new features or resolved issues in this release.

## 25.3.0

### New Features

- The `UniversalViewing` configuration parameters `ConnectorGroupField`, `DistributedConnectorReferenceField`, `WebURLField` and `FileSystemReferenceField` now support nested field structures when searching the Content response for the field values, by separating field names with a forward slash (/). For example, you can set `ConnectorGroupField=GROUPS/CONNECTOR` to find the field value in the following XML:

      <GROUPS>
         <CONNECTOR>MyConnectorGroup</CONNECTOR>
      </GROUPS>

- You can now configure View in universal viewing mode to retrieve document information from a particular field in the Content component index if the connector fails to return the original document. To use this option, set the new `FallbackContentField` parameter to the field name in the `UniversalViewing` configuration section. By default, it uses the `DRECONTENT` field. The parameter also supports nested field structures.

- View has been updated to allow it to fetch documents from NiFi or a DistributedConnector that is protected by OEM licensing.

### Resolved Issues

- When a secure document was added to the View internal cache after viewing with a valid SecurityInfo string, these documents could be subsequently viewed by later requests that did not have a valid SecurityInfo string.

  View now enforces that a valid SecurityInfo string is provided when retrieving secure documents from the cache.

## 25.2.0

### New Features

- View can now read an AES key for data encryption directly from the new `AESKey` configuration parameter in the `[DataEncryption]` section. Previously, it was only possible to read an AES key file from disk (configured with `AESKeyFile`).

  You can use this option to import a key directly from a secret source, such as an environment variable or HashiCorp® Vault. The key protects access to your encrypted data, so OpenText strongly recommends that you do not to supply it as a plain text configuration value. Setting a plain text value returns a configuration validation error, but does not prevent the server from starting up.

- View has been updated to enable it to use NiFi-2 for connector communications.

### Resolved Issues

- The `ProxyPassword` configuration parameter in the `[Viewing]` section accepted only plain text passwords. You can now encrypt this password with the autpassword command-line tool in the same way as for other passwords. Refer to the Knowledge Discovery Administration Guide. to be encrypted (previously, they would only accept this parameter as plain text).

- When on-disk data encryption was enabled, a viewing request with `OutputType` set to `Raw` could return an incorrect value in the Content-Length: HTTP header field.

## 25.1.0

### New Features

There were no new features in this release.

### Resolved Issues

- A View request with highlighting and `Boolean` set to False could fail if the highlight text consisted entirely of non-ASCII characters.

- When using Universal Viewing, retrieving metadata for documents with a large number of sections could be overly slow (possibly causing timeout errors, in the worst case).

## 24.4.0

There were no new features or resolved issues in this release.

## 24.3.0

### New Features

- When you request a raw file (`OutputType` set to raw), View Server now respects the HTTP `Range:` header on the request, and returns a Partial Content (HTTP status 206) response. This change can improve the viewing of video files served from View server.

### Resolved Issues

- View was unable to retrieve certain binary files from NiFi or Distributed Connector when `OutputType` was set to raw.

## 24.2.0

### New Features

There were no new features in this release.

### Resolved Issues

- In the default rendering mode (that is, when `LegacyRendering` was turned off), multibyte Unicode characters were sometimes displayed incorrectly.

## 24.1.0

### New Features

- Two new KeyView options have been added as View configuration parameters to allow you to more easily set the output format for vector and rasterized embedded graphics:

  - `OutputVectorGraphicType`

  - `OutputRasterGraphicType`

  For a full list of available options, refer to the IDOL View Component Help.

  NOTE: These configuration parameters are not available when you set `LegacyRendering` to True. However, you can use the associated KeyView options in a Viewing template, including the new `KVGFX_SVG` option.

### Resolved Issues

- Some `View` actions failed with a HTTP 400 error when the URL returned a redirect response with a #anchor URL fragment.

## 23.4.0

There were no new features or resolved issues in this release.

## 23.3.0

There were no new features or resolved issues in this release.

## 23.2.0

### New Features

There were no new features in this release.

### Resolved Issues

- When using a Memcached cache and page restrictions, View sometimes returned the wrong page.
