# 2025.15

<Warning>
  As of June 30, 2025, `claude-3-opus` is deprecated. The expected removal date for this model is January 2026. [Anthropic recommends migrating](https://docs.anthropic.com/en/docs/about-claude/model-deprecations) to `claude-opus-4-0` before January 2026. We strongly recommend carrying out this migration since `claude-3-opus` support 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.

### Cognigy Voice Gateway

**Released** August 12, 2025

#### Bug Fixes

* Fixed the issue where updating an application via a `PUT` API call to `/v1/Applications/<app_sid>` led to the removal of `call_hook`, `call_status_hook`, and `messaging_hook`. This issue occurred when these values weren't included in the request body

## 2025.15.0

### Cognigy.AI

**Released** July 22, 2025

#### Improvements

* Removed the model selection for the deprecated GPT Conversation Node from the Generative AI Settings section in Manage > Settings
* Added the Legacy label to the `claude-3-opus` [model](/ai/agents/develop/gen-ai-and-llms/model-support-by-feature) to reflect its deprecation by Anthropic
* Added the capability to display typing indicators to end users in [Webchat v3](/webchat/v3/configuration#webchat-behavior) when using [Genesys Cloud Open Messaging](/ai/escalate/handover-reference/genesys-cloud-open-messaging)

### Cognigy Voice Gateway

**Released** July 22, 2025

#### Improvements

* Added automatic trimming of unnecessary silence at the end of generated TTS audio. This improvement enhances the recognition of short spoken replies, such as Yes or No, by ensuring they're detected more quickly and accurately after the AI Agent finishes speaking

**Released** July 22, 2025

* Updated Webchat v3 and Demo Webchat to [v3.26.0](https://github.com/Cognigy/Webchat/releases/tag/v3.26.0)

**Released** July 22, 2025

#### Bug Fixes

* Fixed the issue where, during high load or when many conversations were created simultaneously, system messages about labels added by automation rules appeared as if added by a human agent in the format: `<human-agent-name> added <label-name>`. Now, labels added by automation rules are consistently shown in the chat as messages from Automation System in the format: `Automation System added <label-name>`
* Fixed the issue where audio messages and attachments were sent after the conversation had been resolved

### Cognigy Insights

**Released** July 22, 2025

#### Bug Fixes

* Fixed the issue where retrieving data through `analyticsdata.intent` didn't work properly
* Fixed the issue where Assertions didn't validate SMS data after the execution of Send SMS Nodes
