# 2025.18
* As of September 24, 2025, `gemini-1.5-flash` and `gemini-1.5-pro` are deprecated. [Google recommends migrating](https://cloud.google.com/vertex-ai/generative-ai/docs/learn/model-versions#legacy-stable) `gemini-1.5-flash` to `gemini-2.0-flash` and `gemini-1.5-pro` to `gemini-2.0-flash`. We strongly recommend carrying out this migration since the support for `gemini-1.5-flash` and `gemini-1.5-pro` will be removed from future Cognigy.AI versions.
Refer to the list of all upcoming removals on the [Deprecations and Removals](/release-notes/deprecations-and-removals) page.

## 2025.18.2
### Cognigy.AI
**Released** September 17, 2025
#### Improvements
* Added the End Handover on Participant Change setting to the Handover to Agent Node for the Salesforce MIAW provider. Enabling this setting ends the handover when an agent is removed, relying on the participant change event because [Salesforce can't always guarantee receipt](https://help.salesforce.com/s/articleView?id=000397177\&type=1) of the conversation close event
#### Bug Fixes
* Fixed the issue where configuring OAuth credentials in a Genesys Endpoint failed with the error `Validation failed. Field oAuth2Connection was not allowed`
* Fixed the issue where user IDs with big integer values weren't processed correctly during handover
## 2025.18.1
### Cognigy Voice Gateway
**Released** September 12, 2025
#### Bug Fixes
* Fixed the issue where it wasn't possible to enter new credentials when you selected Deepgram as a speech provider in the Voice Gateway Self-Service Portal for Cognigy SaaS installations
## 2025.18.0
### Cognigy.AI
**Released** September 2, 2025
#### Improvements
* Removed the Beta flag from the new [Handover Providers](/ai/escalate/migration) interface
#### Bug Fixes
* Fixed the issue where the Absorb Context parameter in the Go To Node didn't merge the source and destination Flow contexts as expected
* Fixed the issue in the Cognigy.AI API documentation. Now, GET APIs show the response for the `next` and `previous` cursors
* Fixed the spacing, sizing, and styling issues in the Lexicon and Any Slot input fields to align them with System Slot fields
* Fixed the issue where goals weren't created in Analytics when uploading a Snapshot, which caused missing data in the Goals Performance chart in Insights
* Fixed the issue where users with `projectAdmin` roles couldn't upload a file within the Project they administer. For example, when creating an LLM connection using the Upload JSON File option
* Fixed the issue where users couldn't save CognigyScript expressions in Node fields that support Manual Input, such as the Select Flow and Select Node fields in the Go To Node
* Fixed the issue where the AI Enhanced Output feature failed on Azure-hosted LLMs due to content policy violations
* Fixed the issue where the AI Enhanced Output feature didn't work with the following models: `gpt-4.1`, `gpt-4.1-nano`, `gpt-4.1-mini`, `claude-sonnet-4-0`, `claude-opus-4-0`
* Fixed the issue in the Endpoint settings where the Migrate to Handover Providers button for the Live Agent saved the pre-configured account instead of the manually entered configuration
* Fixed the issue in the Question Node where the Large Language Model list didn't display available models in the following scenarios:
* When LLM Prompt was selected under Reprompt Options > Reprompt Method
* When LLM-Extract Entity was selected from the Question Type list, the LLM Entity Extraction Options section showed an empty model list
* Fixed 500 errors and stack traces caused by malformed OData URLs
* Fixed the issue where additional category IDs weren't applied during handover to RingCentral Engage
### Cognigy Voice Gateway
**Released** September 2, 2025
#### Bug Fixes
* Fixed the `termination_reason` field in the Call Detail Record (CDR) for failed calls in `sbc-inbound`. Now, the `caller abandoned` reason correctly indicates that the caller initiated the call but canceled it before it was answered
* Fixed the issue where multiple `BYE` messages were sent when the voice AI Agent hung up a call in `sbc-inbound`. This fix ensures that each call termination generates only a single event, preventing duplicate call termination notifications
### Cognigy Webchat
**Released** September 2, 2025
#### Features
##### Webchat v3 npm Package
* With [version 3.29.1](https://github.com/Cognigy/Webchat/releases/tag/v3.29.1), Webchat v3 is now officially available as an [npm package](/webchat/v3/embedding/npm). This change makes it easier for developers to integrate, update, and manage Webchat v3 in modern web applications.
#### Bug Fixes

### Cognigy Live Agent
**Released** September 2, 2025
#### Bug Fixes
* Fixed the issue where the end user's profile picture didn't update in the Contact Profile details and the Conversations list. Now, profile pictures display correctly throughout the Live Agent interface
