# 4.81
* The Chatbase analytics integration will be removed in Cognigy.AI 4.82.0. The Chatbase platform has not been supported since 2021.
* The `facebook-bot-messenger` module within a Code Node will be removed in Cognigy.AI 4.83.0.
* The Any Slots feature will be removed in Cognigy.AI 4.84.0. Instead, use the [LLM Entity Extraction](/ai/agents/develop/node-reference/other-nodes/llm-entity-extract) Node to identify Slots in the user input via LLMs.
In recent releases, we have updated the connection settings to Azure OpenAI LLMs and added new parameters, such as the Resource Name.
If you have an older connection (for example, created in the 4.53 release) to Azure OpenAI LLMs, especially Azure OpenAI `text-embedding-ada-002` for knowledge search features, you might encounter the following error when an LLM is triggered:
`Error while performing knowledge search. Remote returned error: Search failed: Could not fetch embeddings due to missing API resource name for Azure OpenAI.`
To resolve this issue, recreate the LLM and the connection so that both have the latest format.
For SaaS installations, we provide the [Cognigy SaaS Service Health](https://status.cognigy.ai/) platform as a public resource. This platform enables Cognigy SaaS customers to access real-time and historical data on system performance and check the status of Cognigy products.
For more information about the platform benefits, read the [Cognigy SaaS Service Health](/ai/administer/installation/saas-service-health) article.

## 4.81.0
### Cognigy.AI
**Released** July 23, 2024
#### Improvements
* Added the Stream Buffer Flush Tokens and Stream Buffer Flush Overrides options to the [Storage and Streaming](/ai/agents/develop/node-reference/service/llm-prompt) in the LLM Prompt Node
* Added the [Enable input sanitization](/ai/agents/deploy/endpoints/data-protection-and-analytics) option to disable HTML text input sanitization within the Endpoint Settings
* Removed the `New` badge from the Knowledge AI sidebar and Knowledge Stores page
* Added a tooltip with the full name for long Flow names in the Flow select field
* Fetched the trainer records from the secondary MongoDB replica, which can be disabled to read from the primary by setting the environment variable `DISABLE_SECONDARY_MONGO_REPLICA_READ_TRAINER`
* Made duplicate trainer record removal configurable with the `DISABLE_DUPLICATE_TRAINER_RECORD_REMOVAL` environment variable. This operation, which can be performance-intensive, can now be disabled on demand
* Redesigned the Cognigy.AI sidebar
* Removed the Cognigy.AI Journeys API
* Improved by preselecting the current flow in the Case Nodes of the Lookup Node
* Changed the styles of Cancel buttons in sidebars
#### Bug Fixes
* Fixed the issue where the Intent description of an attached Flow's Intent was missing in the NLU inference results
* Fixed the issue where the Endpoint editor had problems with saving because of the default value of Enable Quick Replies
* Fixed the issue where an incorrect tooltip text was shown in the Knowledge AI Settings section under Document Processing > Connection to Azure AI Document Intelligence

* Fixed the issue with the Genesys Open Messaging handover provider where messages containing structured content were incorrectly displaying as `UNSUPPORTED_STRUCTURED_DATA`. This issue prevented the structured content from being rendered properly in the message
### Cognigy Voice Gateway
**Released** July 23, 2024
#### Improvements
* Improved by supporting complex `refer-to` and `referred-by` URI
* Added new metrics to track the duration of Voice Gateway commands
* Added the [Enable User No Input Timeout](/ai/agents/develop/node-reference/voice/voice-gateway/parameter-details) option in the Set Session Config Node to enable or disable the User No Input Timeout feature
#### Bug Fixes
* Fixed the issue where the `Contact` header in the `200 OK (INVITE)` response used the `sips` scheme instead of `sip`
* Fixed the issue where the `Contact` header did not contain the private IP on a private CIDR
* Fixed the issue where the `Contact` header in a re-INVITE request had the wrong scheme
* Fixed the issue where users with the Service Provider role were unable to delete an account phone number
* Fixed the issue where escape characters such as `\r`, `\t`, and `\n` in a text lead to invalid SSML when Azure streaming was enabled
* Fixed the issue where using the `inject` API failed when the sessionId was changed through the input transformer. Before 4.81, we stored the Voice Gateway client based on the callSid. The Voice Gateway client is now stored based on the sessionId
* Fixed the issue where no event was sent after a successful `Refer` transfer with the reason `Gone`
* Fixed the issue where an error occurred after hangup when the `ENDPOINT_VG2_TIMEOUT_FOR_AI_RESPONSES_IN_SECONDS` environment variable was set
* Fixed the issue where a timeout was triggered when a message was sent to AI Agent. In some scenarios, no answer is expected. The solution for now is to only trigger the timeout when an environment variable specifying the timeout period is set

### Infrastructure
#### Cognigy.AI + Insights + Agent Copilot
##### Rollback Instructions
In case you need to revert to version 4.80.1, run the following script since we've added a new field for the Endpoints.
1. Establish a connection to the MongoDB instance within your cluster and execute the database script:
```bash theme={null}
kubectl exec -it -n mongodb mongodb-0 -- bash
mongo -u $MONGODB_ROOT_USER -p $MONGODB_ROOT_PASSWORD --authenticationDatabase admin
use service-resources;
db.endpoints.updateMany({},{$unset:{"settings.behavior.enableCollectMetadata":""}});
```
2. Execute the Helm Chart rollback.
##### Insights Schema Migration for PostgreSQL Databases
Due to an improvement to Insights OData, a schema migration is required for all customers using a PostgreSQL database.
This schema migration is a one-time job that runs automatically during the upgrade to release 4.81.0.
The migration job will be disabled in release 4.84.0.
#### Cognigy Voice Gateway
* Updated `vg-freeswitch-mrf` to `0.9.1`
* Added the `AZURE_SPEECH_USE_SINGLE_CONNECTION` environment variable to the `feature-server` Deployment and StatefulSet - container `freeswitch`. It can be controlled via `.Values.freeswitch.azureSttUseSingleConnection`. The default value is `true`
* Changed the freeSWITCH `.Values.freeswitch.bufferSecs` default value to `5` seconds
