15 April 2026 - 1.127 Release Notes

🔖 This is a major update, bringing many new changes and improvements into Nimbus. This update is being rolled out sequentially on our clusters:

Companion Goes to General Availability

With this update, we close the Nimbus Companion preview program and Nimbus Companion becomes generally available to Nimbus customers. Use automated transcription to create a written record of all your incoming audio calls. Let your agents catch up fast on those longer conversations, by providing an AI-powered summarization directly in the UI. With an existing transcript, Companion can also reduce the distracting busywork in your agent's after-call work by automatically suggesting codes and tags best suited to the current conversation.

🔎Added with this update:

• Companion Service Settings - Companion features will become generally available. The UI might provide these features My Sessions and Attendant Console as additional “Companion” widgets. 
  💡All features are individually configurable per service and by default turned off.
  💡"Live Captioning" features remain in preview and will require an additional license.
• New optional Companion Features (Transcription, Summarization, Codes & Tags) all become generally available for Companion licensed users. 
• Codes - New optional “Companion Context” fields for Primary and Secondary Codes, allowing you to describe how Companion should suggest codes automatically after a transcribed inbound audio call.

Nimbus Virtual Users Now Available for Outbound Call with Workflow

Nimbus Virtual Users can now be used in outbound workflows. This enables automated, AI‑driven outbound calls that follow the same configurable workflow logic as inbound scenarios—ideal for proactive customer interactions, surveys, session follow‑ups, or call campaigns without immediate agent involvement.

🔎Added with this update:

• Conversation Handling Activities - The “Add Virtual User” workflow activity supports Outbound Call Audio/Video workflows.
• Modalities Service Settings > Outbound Call > Workflows now supports “Add Virtual User” workflow activity.

Automatic Voicemail Transcription

Save agents from sitting through lengthy voicemail recordings before returning missed calls. With automatic voicemail transcription using Azure Speech Services, transcriptions can now be shown directly in the Nimbus UI (Customer Insights) and delivered as Adaptive Cards in your preferred MS Teams channel, so that agents can quickly skim the message and pick up the phone knowing what the customer needs.

🔎Added with this update:

• Modalities Service Settings: 
  • Added new “Voicemail Transcription” Service Setting to automatically transcribe voicemail. This feature is configurable per service.
  • Added a Speech Recognizers option for Voicemail. 
• With the feature enabled, transcription-enriched Adaptive Cards will be posted to the service's MS Teams channel.

Keep Track of Initial Entry Point of a Call

When a call passes through multiple hands, critical context can get lost. Nimbus now preserves the original number or identity from the moment a call first enters your system, giving agents transparency into where a call was originally received, even if it was later forwarded to a Luware Nimbus service. This also allows intelligently routing calls to preferred agents, ensuring that customer hear a trusted voice.

🔎Added with this update:

• System Fields and Parameters - Added new Nimbus System Data: Original Called Number / Original Called Target Type (User / Resource Account / Service).
• The new Parameters can be shown and used in various areas, such as Nimbus Workflows, Power Automate Connector, My Session Page.

Export Service / User Configuration Data 

Managing audits and operational reviews just got easier. A new export functionality in the Nimbus Service and User Administration lets you capture individual settings as snapshots. This way, you can now keep track of changes over time and see a personal history record. And because the export is powered directly by the internal Nimbus API, you can trust that what you see is what you get: the exact same configuration data — workflows, settings, and licenses.

🔎Added with this update:

• Configuration Export capabilities have been added to Nimbus Admin UI.
• New CSV and JSON export buttons User Administration and Service Administration.
• Possibility to bulk-export multiple entities into single files.

Virtual User - New capabilities and quality of life updates

With the addition of a new bot type (based on GPT realtime), Nimbus expands on Virtual User capabilities. The new “AI Workflow” bot type supports a wider array of use cases within workflows, all wrapped in a Nimbus-native integration and UI experience. Nimbus Administrators and Service Owners can leverage external services and formulate more detailed instructions for the AI on how to proceed with this data.

• Bots - Added extended features with a new bot type “Nimbus AI Services - AI Workflow”.
• Virtual Users - when selecting the “AI Workflow” bot, new capabilities for Web Requests and MCP servers are unlocked. 
  • AI prompt fields expanded considerably to allow for more detailed instructions.
• Conversation Handling Activities - “Add Virtual User Activity” now supports a total 3 different bot variants.
  • With the new “AI Workflow” Bot and Virtual user selected, the activity allows to directly engage with a customer in natural conversation. 
  • Added support for Fallback Parameters. These parameters are filled when the AI cannot fulfill a customer request or fails to validate the data necessary to proceed.

Instant Messaging improvements

Improving on the recent SMS/RCS and WhatsApp integration, Nimbus now offers more clarity on the UI and Configuration, clearly highlighting pending interactions, as well as highlighting potential restrictions imposed by the integration channel in use (e.g. remaining or total SMS length). This avoids costly mistakes by either sending too many or no messages to customers as the constraints were hit, or accidentally ignoring a customer's reply in chat.

• My Sessions and Nimbus Main Menu:
  • Instant Messaging tasks, widgets and menus now show "pending interaction" notifications as red bubbles.
    💡Note that this counter increments increments once per pending task, not acting as a total message count. More details can be found under Instant Message Handling > My Sessions.
  • A added validation for Twilio integration messages (WhatsApp, SMS, RCS) to avoid message sending failures due to oversized messages. Chat Widgets in the My Sessions UI will now show message limits and warnings, also display links to the KB for further information.
  • Conversation Handling Activities > “Message" - Added notes activity behavior when message length (imposed by the channel integration and protocol) is exceeded. The activity will be skipped e.g. when Parameters resolve into messages that would exceed the limit.

Other Changes and Improvements

• Various UI detail improvements made to Attendant Console and other UI areas, primarily to increase contrast and readability.
• Conversation Handling Activities > “Input Customer (Advanced)" now supports voice-enabled IVR with freely configurable Speech Recognizers.
• Virtual Users  - Flow description fields now allow up to 5000 characters for more detailed prompts and richer context.
