# 2026.16 (latest)

<Danger>
  Removals:

  * OpenAI's and Microsoft Azure OpenAI's `gpt-5-chat-latest` models have been removed. To avoid any issues with your AI Agent, migrate to a more modern model, for example, `gpt-5.6-sol`.
  * The **Handover Settings** section has been removed from the Endpoint settings. Consequently, the **Legacy** option was removed from the **Handover Provider** list in the Handover to Human Agent, Question, and Check Agent Availability Nodes. If you haven't migrated to the new interface for handover providers, refer to the [migration guide](/ai/escalate/migration).
</Danger>

<Warning>
  Deprecations:

  * [Cognigy Serverless](/ai/for-developers/extensions#cognigy-serverless) is required starting with Cognigy.AI 2026.21.0. The legacy Extension runtime for trusted and untrusted Extensions has been deprecated. The removal is planned for Cognigy.AI 2026.21.0.
    * For SaaS installations, Cognigy performs the migration and no action is required. If Cognigy hasn't contacted you, your Extensions are already running on Cognigy Serverless.
    * For on-premises installations, [install Cognigy Serverless](/ai/administer/installation/serverless-installation) before upgrading to Cognigy.AI 2026.21.0. Otherwise, all Extensions will stop working after the upgrade.
  * As of Cognigy.AI 2026.4.0, the [Step](/insights/explorers/step) and [Message](/insights/explorers/message) explorers in Insights are deprecated. These explorers will remain functional until their full removal in Cognigy.AI 2026.18.0.
</Warning>

## 2026.16.0

### Cognigy.AI

**Released** August 4, 2026

#### Features

##### Real-Time Queue Notifications for Genesys Cloud Open Messaging

Introduced real-time queue notifications for the Genesys Cloud Open Messaging handover provider. End users can now receive estimated wait-time updates while waiting for a human agent. This feature improves transparency during handovers. For more information, refer to [Real-Time Queue Notifications](/ai/escalate/handover-features/real-time-queue-notifications#configure-settings-in-genesys-cloud-open-messaging).

#### Improvements

* Added the [`POST /v2.1/projects/{projectId}/logs/package`](/api-reference/logs-v21/package-log-entries-into-a-downloadable-file) and [`GET /v2.1/projects/{projectId}/logs/package/{logsFileId}/download`](/api-reference/logs-v21/download-a-packaged-logs-file) API methods to package log entries into a JSON file you can download. These API methods allow you to avoid paginating through logs when using the [`GET /v2.1/projects/{projectId}/logs`](/api-reference/logs-v21/get-log-entries) API method
* Standardized the Endpoints-specific API authentication key header for the [REST](/ai/agents/deploy/endpoint-reference/rest) and [Webhook](/ai/agents/deploy/endpoint-reference/webhook) Endpoints. Now, use the `x-cognigy-endpoint-key` request header for both Endpoints instead of `x-rest-endpoint-key` or `x-webhook-key`
* Added the `isMasked` field to the [GoalEvents](/ai/agents/analyze/odata#goalevents) collection for the Cognigy.AI OData endpoint 2.4
* Removed the beta label from [NiCE CXone handover](/ai/escalate/handover-reference/nice-cxone/overview) providers. They are now displayed as generally available
* Increased the default maximum upload size for UI uploads of [Snapshots](/ai/agents/deploy/snapshots#limitations) and [Packages](/ai/platform-features/packages#limitations) to 8 GB. Direct Cognigy.AI API upload limits remain unchanged
* Increased the default size limit for the [Context](/ai/agents/develop/ai-agent-memory/context#limitations) object from 65 kB to 256 kB

#### Bug Fixes

* Fixed the issue where newly created Locales and Snapshots were displayed in the Locale and Snapshot lists in the Interaction Panel only after the page was reloaded
* Fixed the issue where Cognigy Serverless unexpectedly terminated Extension executions
* Fixed the issue where opening Flows, Endpoints, Locales, and Snapshots returned a `500` error
* Fixed the issue where the status message for the NiCE CXone handover provider showed the incorrect text
* Fixed the issue where the names of API keys created without a name or named `ApiKey` weren't displayed in the API Keys list on the My Profile page. Now, you must enter a name when generating an API key
* Fixed the issue where updating or deleting an AI Agent failed with a `500 Internal Server Error`
* Fixed the issue where fullscreen mode in the mock code editor didn't close when the user pressed `Escape` after typing in the editor
* Fixed the issue where file-size limits weren't enforced for Snapshots and Packages uploaded through the UI
* Fixed the issue where incorrect text was displayed in the Copilot: Set Grid Node
* Fixed the issue where assertions always failed in a Playbook run from the Interaction Panel Test tab
* Fixed the issue where messages from Live Agent to the end user weren't displayed when the Flow included a data-only or an empty Say Node

### Cognigy Voice Gateway

**Released** August 4, 2026

#### Improvements

* Added a Region option to the [Voice Preview settings](/ai/agents/test/voice-preview#set-up-a-speech-provider) for the Deepgram speech provider

#### Bug Fixes

* Fixed the issue where barge-in failed after a previous barge-in was incorrectly handled

### Cognigy Live Agent

**Released** August 4, 2026

#### Improvements

* Improved service stability and performance

### Cognigy Insights

**Released** August 4, 2026

#### Bug Fixes

* Fixed the issue where the `This Session Transcript was deleted` message was displayed instead of the conversation when a session was opened from a Contact Profile
* Fixed the issue where very large conversation messages weren't recorded in Insights
* Fixed the issue where Conversation Analyzer failed for OpenAI's and Microsoft Azure OpenAI's `gpt-5.6` models because an unsupported parameter was sent in the request to the LLM provider
