13 May 2024 - 1.93 Release Notes

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

Cluster Update on
United Kingdom 01 / Switzerland 02 13.05.2024
Switzerland 01 / Germany 02 14.05.2024
Germany 01 15.05.2024
  • Dashboard Widgets - Service / User Limitation - To keep the performance on huge Dashboard Widgets manageable, query limits of 200 users / 200 services each were introduced on filtering, e.g. when large Organization Units containing many users and services were selected as “Data Source”.
    • A warning and counters are shown when a total user / service count limit is exceeded.
    • The limit applies summed-up across all widgets on the same Dashboard.
  • Assistant - Blind Transfer - 💡Only for incoming calls 
    • Added a “Blind Transfer” button in Assistant for ongoing service calls. Clicking it allows to search for a name or type in a PSTN Number to quickly transfer the call towards.
  • Historical Sessions - Service Session Details
    • Introduced a Service Session Details Popup in the Historical Sessions view.
    • The session details popup shows call metrics, users involved, Codes, Tags, Session Details for a service session.
    • Session details are shown as configured in Extensions Service Settings per service. Historical call details are only stored when the “Store Conversation Context Data” setting was enabled back when a service session was concluded.
  • Power BI Improvements:  
    • DayOfMonth which is used in the Sessions Overview tile "Session Volume by date and Hour, % Handled Rate" has been updated to ensure that it sorts in chronological order.
    • When drilling down to the day of month, the data is now sorted in a meaningful way.
  • GDPR - Historical Data Retention Settings
    • Data Retention Time: New: Added a “Data Retention Time” setting to Tenant Administration > Data Privacy. 💡 This setting was released read only. We plan to make the retention threshold setting user-configurable in the near future (up to 24 months).
    • Unchanged behavior: Historical data exceeding the retention time is purged within the next 24 hours.
  • Service Distribution Settings - Auto Redirect in Emergency Case.
    • Added a new toggle Auto Redirect in Emergency Case in Distribution Service Settings. You can define where to forward calls when they are being blocked by Nimbus.  Currently, there are three options for redirecting calls:
      • PSTN number
      • User UPN
      • Service UPN
    • This feature is meant as a fallback during technical analysis of service degradation/downtime to allow to route incoming calls to a temporary (emergency) number. Calls will be blocked from being handled in regular workflows and distribution, allowing Luware technicians to perform maintenance and analysis. 💡Note that an “Emergency Case” is engaged and managed by Luware System Administrators. When it applies, Luware support blocks the calls on cluster level. In such case you will find more information on
  • Power Automate Connector - Address Books limitation
    • Added character limits per Address Books contact properties within Power Automate Connector > Flow Actions. Specific backend error messages will be shown when these limits are exceeded.
  • Other Changes and Improvements
    • Adaptive Cards “Solved”  status -  Fixed an issue that prevented Adaptive Cards with status “New” from being marked as “Solved”. ☝ Please note that this fix will only work on newly incoming Voicemails and their corresponding Adaptive Cards.
    • Extensions Service Settings "Store Custom Context Data" option
      • Historical Data - Fixed an issue that prevented Custom Parameters from being correctly stored historically, according to the "Store Custom Context Data" setting individually enabled per Service Settings.
      • KB: Updated the "Store Custom Context Data" wording to make its effects more clear, when storing (potentially private) parameter data in a Multi-Service Transfer context.
    • Workflows
      • Workflows > Input Customer Activity (IVR) - Improved internal handling of DTMF inputs to speed up processing.
      • Workflows - Fixed a workflow scenario issue that prevented IVR recognition after previous transfers.
    • Instant Messaging / Interact
      • Added support for emojis within chat.
      • Updated limit of 249 characters for the initial chat topic (service name + customer's name).
    • Other Fixes and Improvements

22.April 2024 - 1.91-4 Release Notes

Feature deployment (Wave 2)

🔖 / 🔥 This is a combined feature toggle and hotfix update. We also enabled Transcription (Beta) capabilities on the remaining tenants. 

UK01 / CH02* 22.04.2024
CH01 / DE02* 23.04.2024
DE01 24.04.2024
1.91-4 Modality and Transcription planned deployment dates

* For this cluster features were already deployed during 1.91-3. For feature descriptions read on further below.


Hotfixes and Improvements - changes on existing functionality:

  • Attendant - Consultation Call - Fixed a UI status delay issue which prevented outright taking a parked call back after a previous consultation call.
  • My Sessions Status updates:
    • Fixed an issue that showed a terminated call still as active on the UI.
    • Fixed an issue where task status updates on “My Sessions” were not immediately  reflected.
  • Non-/Personal Dashboards > Dashboard Widgets  > Service KPI Tabular - Fixed an erroneously long number shown in the “Longest Waiting Task” column of the “Service KPI Tabular ” widget.

15.April 2024 - 1.91-3 Release Notes

Feature deployment (Wave 1)

🔖 This is a feature toggle update. It's finally time to increase the list supported modalities. We also enabled Transcription capabilities.

DE02/CH02 16.04.2024
Other clusters See above, 1.91-4
1.91-3 Modality and Transcription deployment dates
  • Email is now here as new supported modality.
  • Instant Messaging (Chat) was rolled out for a while yet, but was reliant on Microsoft public preview functionality. As this restriction is now removed, handling instant messaging is now supported in production.
    • Instant Messaging is now usable in production.
    • The dependency on Interact remains in place, as native MS Teams Client support is still missing. In the meantime we're using the time to lower the technical requirements and simplify related setup steps for the productive rollout.
    • Instant messages are handled via Adaptive Cards and Assistant App, you can learn more on Instant Message Handling.
  • Transcription Feature (Closed Beta) - Transcription allows to record a customer-to-Nimbus-user interaction in real time and keep written record of the entire content. The main interaction remains in the My Sessions UI and works otherwise in the background without further actions necessary by the end-user.
  • General Licensing UI and related KB changes - As the new modalities also brought many changes to the Nimbus UI, restructuring of license display and related settings was necessary. We took the opportunity to redesign some parts of the Knowledge Base to make the transition easier. 
  • Knowledge Base: 
    • Completely reworked the Workflow Activities Overview to allow readers to distinguish modality-specific properties and settings, as well as better see license requirements.
    • Completely reworked the Nimbus Features matrix to match the Nimbus UI and licensing. This should allow users to easier understand what additional features come with each additional license toggle.

25. March 2024 - 1.91 Release Notes

🔖 This last major feature update, was rolled out on all productive clusters already. The update leaned heavily into UX and UI improvements alongside with many, less-visible backend changes.

27 Feb 2024 - 1.90 Release Notes

🔖 This is a major feature update, bringing many new changes and options into Nimbus. This update will be rolled out sequentially on our clusters: 

Cluster Update on
United Kingdom / Germany 02 26.02.2024

Ongoing backend improvements - Learn more

In recent months - especially in our German cluster -  the call volume has increased massively. As Nimbus is growing we want to ensure to offer you the usual high quality in future. To achieve this, we currently focus more development resources on making extensive adjustments to our infrastructure.  In recent and coming weeks we implement backend design changes to better handle the current load, react to future spikes and thus ensure availability at the usual level.

What does this entail for our customers?

  • To unlock the full potential of Microsoft Teams with Luware Nimbus, we continue to work on exciting new features. However, we have decided to hold back some major features for a few more weeks in order to be able to focus on transitioning the infrastructure.
  • In order to alleviate the load on the system that would arise with new customers, we will add additional capacity for the regions of Germany and Switzerland by means of new clusters.
  • As soon as the transition within the infrastructure is complete, we will also make the new features available in our production environment.
  • Assistant Changes
    • Introduced as a new “Appearance” tab in the Settings.
    • Assistant  > Settings > “Appearance” - New “Bring to the foreground” option
      • Default disabled. When enabled, brings Assistant to the foreground upon incoming events (Session, RONA, etc.)
      • Configurable via MSI Switch in the Assistant Installation.
    • Restructured options to “Notifications” and “Appearance” tabs in the Settings.
    • Open Logfolder - Icon replaced, text moved into tooltip. 
      • Moved from the Info page into the menus.
      • Fixed a German translation issue on the Logfiles-Folder description.
  • Other Fixes and Improvements
    • Tenant Settings > Extensions Tab > Presence Tracking: Added a “copy fields to clipboard" so guest users can be easily retrieved for invitation into the Azure Tenant. 
    • Resources > Upload validation  - Introduced an upload limit validation. Prior to upload, individual audio files are checked to have maximum of 10 min lenght or 20 MB size. 💡If you need to chain multiple files, please resort to using multiple “Announcement” activities or use Playlists.
    • Address Books: Now following Organization Units “Read along the path” rule.
      • Previous behavior: Users were formerly just able to find Address Books on root level. 
      • New behavior: Address Books correctly follow the User's Organization Unit level. For example, a user should: 
        • a) have access to OUs on their level and Tenant OU address books (up the tree to the root)
        • b) not have access to Address Books on same-level OU (even if the user could be part of that service). 
    • Workflows > Input Customer Activity: Reduced "Max Input Timeout" to a maximum of 30 min. Existing Workflow items will not be affected.
    • Historical Sessions  - UI Fix: Fixed filter dropdown entries in dark theme showing the wrong font color.
    • Attendant Console - Contact Groups: Fixed cut-off icon shown next to user icons when editing contact groups.
    • Opening Hours - UI Fix and UTC time zone change:
      • Corrected Special pulldown colors for Opening Hours Default Type pulldown to match the periods
      • Editing single exceptions from a series of events will now correctly convert the period to UTC-based timezones based on on the original event, ignoring the users current device timezone. ☝ Existing Opening Hours periods will NOT be migrated to avoid impacts on existing produtive hours. When you create new recurrent series exceptions, the new behavior will apply.
  • Relevant Knowledge Base Changes. 
    • Use Cases Rework - As our Use Cases section has grown significantly over the last years, we aim to rework it in both structure and content.
      • To keep the visual load on our visitors smaller, we will hide Use Cases in most main menu entries, instead listing them in one or several categories such as Power Automate and Nimbus Administration. 
      • You can still find all hidden pages in our Page Index located at the footer of our KB.
    • KB Resource Library - As all our products rely on Microsoft Azure infrastructure, Whitepaper Documents and other technical information will get more and more into focus. To reflect this, we introduced a new Resource Library section prominently in the Knowledge Base root. As a start we list our whitepapers therein, but will continue to expand as more technical or user-data relevant information become available.

02 Feb 2024 - 1.89-3 Release Notes

🔥This is a minor hotfix update, bringing many new changes and options into Nimbus.

  • Attendant Console - Fixed an issue that prevented display names to be shown in contact groups. 
  • Initial improvements to our backend infrastructure were made to ensure a smooth call experience with further growth of the platform. In the coming weeks were are further committed to more adjustments to our infrastructure in order to cover the increasing load more efficiently and ensure ongoing availability at the usual level.

19 Jan 2024 - 1.89-1 Release Notes

🔥This is a minor hotfix update, bringing many new changes and options into Nimbus.

  • Call Handling - Fixed an issue that caused users in After Call Work (ACW) to be selected for calls despite being Off Duty or DND.

18 Jan 2024 - 1.89 Release Notes

🔖 This is a major feature update, bringing many new changes and options into Nimbus.

  • Elimination of audio delay for outbound calls (Postponed due to delayed MSFT deployment) -  Improved delay handling during outbound calls, causing customer and agent to hear each other only after a while. Customer and Agent should now hear each other immediately.
  • Flexible Licensing / User Modalities - This update will introduce more licensing flexibility, adding “Modality” settings for users. This will work in conjunction with the enabled modalities on service level, effectively limiting the channels on which users of that service will receive Nimbus tasks.
    • Introduction of modality addons for individual users. For each user the following modalities can now be configured individually:
      • Instant Messaging (still not enabled on productive tenants) (Chat Handling) - default: disabled
      • External Task - default: disabled. 💡Existing users with a Contact Center license which had this modality enabled already will be migrated.
      • The License Management view has been updated accordingly to reflect the new user modality options.
      • Modalities on Nimbus Portal - As individual modalities can now be toggled per user, the modalities are also now shown in the Nimbus Portal (e.g. My Services and Dashboard  views).
    • Design changes to Service Administration and User Administration UIs (Modality tabs) to reflect the new modality selections.
    • Interact is now consolidated as a Service Addon with the according licensing contingency connected to License Management. 
  • Assistant - Status Display: The Luware Nimbus Assistant will now distinguish between the availability status for both Microsoft Teams and Luware Nimbus, allowing users to quickly differentiate between their different availability statuses. The Luware Nimbus availability status is now displayed in a new banner, making it easily visible. The Microsoft Teams status will be moved to the user icon at the top of the Nimbus Assistant. 
  • Assistant App changes and fixes: 
    • The “Notifications” tab in the settings now allows to configure notifications per modality (IM, External Task)
    • Fixed an issue with Extended toast-pop up not being displayed during a call
    • Assistant - Call Templates - Fixed a rare issue where call details from a cancelled call were not cleared correctly and shown on the followup call.
  • Historic Reporting - Aggregated Data, Short Abandons, OpeningHours 
    • Aggregated user an service statistics data is now part of the OData interface. Nimbus now generates 15 minutes timeslots and stores it in the reporting database. Users with WFM (Workforce Management Tools) use this data to get user involvements within service sessions e.g. to plan shifts with accurate data. ☝️ Please note: Reporting data prior to this update is not aggregated / migrated retroactively.
    • Added aggregation support to TiDB (OData interface) in 15' intervals each. Data is aggregated for: 
      • User sessions
      • Service user sessions
      • Service statistics
  • Reporting: Short Abandons - New settings added to General Service Settings  > Reporting section > Short Abandons Threshold
    • Calls below this threshold are considered “Abandoned" and also added to reporting / aggregated data.
    • Added Opening Hours service session data to the ServiceSessions table in the OData interface. 
    • Opening Hours are now also included a BI Template update.
    • KB: Updated the Nimbus Reporting Model to reflect aggregated and Opening Hours data.
  • Chat Handling Improvements (still disabled on productive tenants at this point):
    • Chat Handling  / Use Case - Setting up Instant Messaging  - removed the requirement for an own ACS instance requirement.
    • Modalities Tenant Settings  - Instant Messaging tab.
    • Now allows to invite 2 guest users instead of ACS instance (invited on the tenant level, similar to presence tracking)
    • New account info messages belwo form field inform about the account guest status
    • New Test UPN field to send a test chat message
  • Workflows - New Wait for Parameter Activity: Will wait for any Parameters changes away from the default (e.g. within Flow Actions). This feature allows you to pause your Luware Nimbus workflows for a define period so that Power Automate can update the value of a parameter, for example from your CRM system. The element will wait a defined time and play either a TTS you define or a resource you provide (e.g. music).
  • Nimbus Power Automate Connector (MS Flow): 
    • 💡As a reminder: Future feature updates will only be added to the new (to be certified V1) connector. Existing custom connectors (V0) will only receive minor updates and fixes to ensure ongoing productive use. When a transition or related action is necessary, we will inform about necessary steps via release notes and with according advance notification.
    • As the new Power Automate Connector is still undergoing Microsoft Certification (to be made available in the Microsoft store), we started updating first KB pages. 
    • KB changes:
      • Added a Legacy and Certified Connector Differences page to explain technical differences and prepare all users for the upcoming transition.
      • Reworked Trigger Events and Flow Actions pages mentioning first connector differences.
      • Nimbus Power Automate Connector page split up and reworked to make future updates easier to read.
      • Separated page: Update Nimbus Power Automate Connector
      • New “Integrations” category started in the Knowledge Base.
  • V1 Connector changes:
    • Fix / Change:  only "Enterprise Routing" and "Contact Center" licensed Services are shown in the Action / Trigger pulldowns. This has already been the case according to the Nimbus Features matrix, but was never checked within service / user pulldown entries.
    • Previously - if you call the "Update Task" action multiple times - you had to provide all previous values (e.g. for the customer details). Otherwise set values get overwritten with NULL/null.
    • The new V1 connector now allows to “skip” overwriting values for properties passed with null/NULL to backend by using the function “string(null)”. Also see Stack Overflow source
  • Other Changes and Improvements:
    • Dashboards - All users with rights to edit Non-Personal Dashboards in the Admin UI can now add any widget. This does not impact the filtering approach on the Frontend.
    • General Service Settings  - New GDPR setting Hide on Historical Sessions page - will hide the service and related tasks from the page.
    • Outbound Service Call / Call On Behalf - Now shows alternative phone destinations on existing contacts within search results.
