### Release Overview

{% tabs %}
{% tab title="CXI Teams" %}

#### **Akixi CXI Teams v4.9.1**

The Akixi CXI Teams v4.9.1 client is a minor maintenance release focused on strengthening platform security and ensuring continued stability following the introduction of Cloud Config in version 4.9.

This update includes the remediation of a DLL hijacking vulnerability through the implementation of secure DLL load paths and Microsoft safe search mode, improving protection against privilege escalation and malicious DLL injection. In addition, regression testing has been completed across all CXI Teams client variants to verify compatibility and stability for this release.

Together, these updates ensure a secure and consistent experience for Teams-integrated CXI environments, maintaining compliance with Akixi’s enterprise-grade deployment standards.

**Minimum Requirements:**

* **Akixi CX Platform:** v3.3.2 or later

{% tab title="GI Cara (Cisco BroadWorks)" %}

#### **Go Integrator Cara (Cisco BroadWorks) v4.9.1**

The Go Integrator Cara v4.9.1 client is a maintenance release focused on improving call centre presence accuracy, agent state visibility, and overall platform stability for Cisco BroadWorks environments.

Building on the feature enhancements introduced in version 4.9, this release refines ACD presence handling, ensuring agent join/unjoin events and call queue states update reliably across the client interface. These improvements strengthen the accuracy of queue participation displays and eliminate inconsistencies previously seen in multi-agent environments.

Version 4.9.1 also includes critical security and stability updates. A DLL hijacking vulnerability has been remediated through enforced secure load paths and Microsoft safe search mode, while additional fixes improve event synchronisation, add-in performance, and image handling. Together, these updates deliver a more robust, secure, and consistent experience across BroadWorks deployments.

### **New Features**

{% tab title="GI Nava (Netsapiens)" %}

#### **Go Integrator Nava (Netsapiens) v4.9.1**

The Go Integrator Nava v4.9.1 client delivers a focused maintenance update aimed at improving reliability, event handling, and state accuracy within Netsapiens environments.

This release resolves several long-standing issues affecting call state visibility, desk phone event persistence, and DND synchronisation. Agents now experience accurate call and presence updates, with the client correctly reflecting when calls are answered by another user or when DND is enabled — even if the Presence window is closed.

In addition to these behavioural refinements, version 4.9.1 includes important platform-level updates that enhance security and ensure compatibility with current Windows and .NET environments. DLL handling has been hardened through secure load paths and Microsoft safe search mode, reducing exposure to injection vulnerabilities.

Together, these updates improve client resilience and deliver a more consistent and predictable experience for Netsapiens-based users.

#### **Go Integrator WxC (Cisco Webex Calling) v4.9.1**

The Go Integrator WxC v4.9.1 client is a maintenance release focused on improving reliability, security, and integration stability for Cisco Webex Calling environments.

This release enhances compatibility with current Webex Calling APIs and refines the handling of authentication and event synchronisation. Users benefit from smoother operation during CRM-linked searches and call control actions, as well as improved reliability in hybrid Webex and desktop client configurations.

Version 4.9.1 also delivers important security and stability improvements. DLL handling has been hardened through the enforcement of secure load paths and Microsoft’s safe search mode, mitigating the risk of DLL hijacking. Additional refinements address image retrieval reliability in v3 add-ins and ensure a consistent and predictable user experience across the Venus client suite.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://akixi.gitbook.io/cx-release-notes/CmZjPH4KJOE9hML1qQw8/akixi-cxi-client-release-notes/akixi-cx-integration-release-notes/v-4.-client-windows/cxi-v4.9.1-10735.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
