After the removal, AI Agents using these Nodes will stop working properly. We strongly recommend migrating to [Voice Gateway Nodes](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/voice/voice-gateway/overview) before the removal date. > [!WARNING] > > In Cognigy 2025.25.0, transformers will start using the `axios` library for handling HTTP requests internally instead of `request-promise`. This change occurs to improve security and maintainability. The following HTTP request options will still be supported: > > * **URL/Endpoint Configuration** — `uri`, `url` > * **Request Method** — `method` > * **Request Headers & Configuration** — `headers` > * **Request Body/Data** — `form`, `json` > * **Query Parameters** — `qs`, `qsStringifyOptions` > * **Authentication** — `auth` > * **Connection & Network** — `proxy`, `maxRedirects`, `gzip`, `encoding` > > If you use other HTTP request options, review your transformer code to ensure it is compatible with the new `axios` library before the release of Cognigy 2025.25.0. > [!WARNING] > > As of Cognigy 4.91.0, the Understood Messages concept is deprecated. Use the [Goals and Tasks](https://docs-classic.cognigy.com/ai/agents/analyze/goals-and-tasks/overview) concepts to evaluate whether your AI Agent understood a particular phrase. In Cognigy 2025.19, the charts related to this concept were removed from the Insights reports. > > As of Cognigy 4.91.0, the `understood` field in the Cognigy OData endpoint is deprecated. The full removal of the `understood` field from the OData endpoint is planned for Cognigy 2026.1. Use the [Goals collection](https://docs-classic.cognigy.com/ai/agents/analyze/odata.md#goals) in the Cognigy OData endpoint. > > Refer to the list of all upcoming removals on the [Deprecations and Removals](https://docs-classic.cognigy.com/release-notes/deprecations-and-removals.md) page. > [!TIP] > > Help us improve our product documentation on `docs.cognigy.com` by sharing your thoughts in a [quick survey](https://forms.office.com/e/xnqneVasp2). Your feedback shapes the future of our content! ## 2025.23.2 ### Cognigy **Released** December 3, 2025 #### Bug Fixes * Fixed the issue where Cognigy OData audit events contained sensitive information ## 2025.23.1 ### Cognigy **Released** November 19, 2025 #### Bug Fixes * Fixed the issue where Microsoft Azure OpenAI models using the API Key connection type with custom URLs failed * Fixed the issue where a Tool Node couldn't be added to the LLM Prompt Node ### Cognigy Voice Gateway **Released** December 3, 2025 #### Bug Fixes * Fixed the issue in `feature-server` where the initial connection to Cognigy required more attempts than expected ## 2025.23.0 ### Cognigy **Released** November 11, 2025 #### Features ##### AI Agent Knowledge Tool Introduced the knowledge tool for AI Agents. This feature allows you to easily add a knowledge tool to your AI Agent to access Knowledge Sources in the [AI Agent editor](https://docs-classic.cognigy.com/ai/agents/develop/manage-ai-agents.md), [AI Agent Node](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/ai/ai-agent.md), or [LLM Prompt Node](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/service/llm-prompt.md) #### Improvements * Added the option to define a custom header to authenticate through [OAuth 2.0 in the Azure OpenAI LLMs](https://docs-classic.cognigy.com/ai/agents/develop/gen-ai-and-llms/providers/microsoft-azure-openai.md) * Added the [GET Latest Log Entries](https://docs.cognigy.com/api-reference-logs/logs/get-the-latest-log-entries) API endpoint to retrieve Cognigy logs with improved performance. By default, this endpoint has a time window of 2 hours. You can change the time window by setting the `FEATURE_ACTIVE_LOGGING_WITH_TAIL_CUT_OFF_HOURS` environment variable in the Helm chart. However, larger time windows may cause lower performance. If you need to retrieve logs over a very long period of time, for example, all your logs, you can use the [GET Log Entries](https://docs.cognigy.com/api-reference-logs/logs/get-log-entries) API endpoint. For better performance, pass the `startDate` and `endDate` parameters to the endpoint #### Bug Fixes * Fixed the issue where the Question Node didn't recognize email addresses containing the `old` substring * Fixed the issue where missing or incorrect Intents were displayed in debug messages * Fixed the issue where handover cancellation messages appeared inconsistently for human agents using Genesys Cloud Open Messaging * Fixed the issue where user events messages were included in conversation transcripts * Fixed the issue where Flows implemented from Snapshots checked the incorrect Project ID * Fixed the issue where GET methods displayed `previous` and `next` parameters, and the `extension` parameter of the `/v2.0/flows/{flowId}/chart/nodes/{nodeId}` endpoint was listed as `enum` type.
