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](https://docs-classic.cognigy.com/ai/escalate/migration.md). > [!WARNING] > > Deprecations: > > * The [Extension runtime](https://docs-classic.cognigy.com/ai/for-developers/extensions.md#extension-runtime) is required starting with Cognigy 2026.21.0. The legacy runtime for trusted and untrusted Extensions has been deprecated. The removal is planned for Cognigy 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 the Extension runtime. > * For on-premises installations, [install the Extension runtime](https://docs-classic.cognigy.com/ai/administer/installation/serverless-installation) before upgrading to Cognigy 2026.21.0. Otherwise, all Extensions will stop working after the upgrade. > * As of Cognigy 2026.4.0, the Step and Message explorers in Insights are deprecated. These explorers will remain functional until their full removal in Cognigy 2026.18.0. > * The [`GET /v2.0/profiles`](https://docs-classic.cognigy.com/api-reference/contact-profiles/get-contact-profiles) API method has been deprecated. The removal is planned for Cognigy 2026.24.0. Use [`GET /v2.1/profiles`](https://docs-classic.cognigy.com/api-reference/contact-profiles/get-contact-profiles-performance) instead for improved performance when retrieving Contact Profiles. ## 2026.16.1 ### Cognigy Voice Gateway **Released** August 18, 2026 #### Bug Fixes * Fixed the issue where the audio connection wasn't properly updated during certain call transfers, causing audio issues after the transfer * Fixed the issue where DTMF-only barge-in settings weren’t restored after the system finished waiting for caller input. As a result, calls incorrectly accepted speech as an interruption when only key presses were allowed * Fixed the issue where speech transcription unexpectedly reconnected after a call transfer. This issue also occurred after a speech provider failover * Fixed the issue where the system reported a media path change as successful while the call continued using the previous path * Fixed the issue where audio failed to decrypt after one call side disconnected while the other remained active ## 2026.16.0 ### Cognigy **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](https://docs-classic.cognigy.com/ai/escalate/handover-features/real-time-queue-notifications.md#configure-settings-in-genesys-cloud-open-messaging). #### Improvements * Standardized the Endpoints-specific API authentication key header for the [REST](https://docs-classic.cognigy.com/ai/agents/deploy/endpoint-reference/rest.md) and [Webhook](https://docs-classic.cognigy.com/ai/agents/deploy/endpoint-reference/webhook.md) Endpoints. Now, use the `x-cognigy-endpoint-key` request header for both Endpoints. The legacy `x-rest-endpoint-key` and `x-webhook-key` headers are still accepted for backward compatibility, but `x-cognigy-endpoint-key` takes precedence if both are provided * Added the `isMasked` field to the [GoalEvents](https://docs-classic.cognigy.com/ai/agents/analyze/odata.md#goalevents) collection for the Cognigy OData endpoint 2.4 * Added the [`POST /v2.1/projects/{projectId}/logs/package`](https://docs-classic.cognigy.com/api-reference-logs/logs-v21/package-log-entries-into-a-downloadable-file) and [`GET /v2.1/projects/{projectId}/logs/package/{logsFileId}/download`](https://docs-classic.cognigy.com/api-reference-logs/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`](https://docs-classic.cognigy.com/api-reference-logs/logs-v21/get-log-entries) API method. The methods are available to some customers via the `FEATURE_PACKAGE_LOGS` feature flag. Contact [Cognigy technical support](https://docs-classic.cognigy.com/help/get-help.md) to activate them for your installation * Removed the beta label from [NiCE CXone handover](https://docs-classic.cognigy.com/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](https://docs-classic.cognigy.com/ai/agents/deploy/snapshots.md#limitations) and [Packages](https://docs-classic.cognigy.com/ai/platform-features/packages.md#limitations) to 8 GB. Direct Cognigy API upload limits remain unchanged * Increased the default size limit for the [Context](https://docs-classic.cognigy.com/ai/agents/develop/ai-agent-memory/context.md#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 the Extension runtime 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 the Region option to the [Voice Preview settings](https://docs-classic.cognigy.com/ai/agents/test/voice-preview.md#set-up-a-speech-provider) for the Deepgram speech provider * Added the option to opt in to the [Deepgram Model Improvement Program](https://docs-classic.cognigy.com/ai/agents/test/voice-preview.md#set-up-a-speech-provider) for Deepgram and Deepgram Flux under **Speech > Speech Service** in the Voice Gateway Self-Service Portal. Opting in allows Deepgram to use call audio and transcripts to improve its models and may reduce per-request costs. Customers can opt out to keep their call data private #### 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 ### Infrastructure #### Version Compatibility Matrix The version compatibility matrix was updated for the following Cognigy products: * [Cognigy, Insights, and Agent Copilot](https://docs-classic.cognigy.com/ai/administer/installation/version-compatibility-matrix) * [Cognigy Live Agent](https://docs-classic.cognigy.com/live-agent/installation/deployment/version-compatibility-matrix) * [Cognigy Voice Gateway](https://docs-classic.cognigy.com/voice-gateway/installation/version-compatibility-matrix) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
