v3.8.4.1 Deployed on 26/05/2026

• [TIS2020-3371] – Synchronization of the company agreements with the outbound interfaces
  Introduced a semi-automated workflow for linking company agreements with outbound interfaces. When requesting or editing a company agreement, users can opt in to data exchange via a new checkbox. Selecting it triggers a notification to TIS admins, who can then link the agreement to a specific outbound interface. Linked agreements remain intact when edited, ensuring continuous data flow.
• [TIS2020-3411] – Wagons and Containers issues and further optimizations
  Continued improvements and optimisations in the wagons and containers logic based on analysis of additional GPS data.
  Improved association of wagons to trains, reducing missing associations where IM data is available.
• [TIS2020-3450] – Task List for Approvals
  Introduced a new "Tasks" menu entry that provides company administrators with a centralized list of pending approvals, including user registration requests, company agreement requests. Email notification links now redirect to the task list, and tasks display a pending/done status with a visual red-dot indicator for open items.
• [TIS2020-3470] – Show Nearby Trains based on current location
  Added a GPS-based "Nearby Trains" feature. Users can tap a GPS icon button on the map to center the view on their current location and display all running trains within a configurable radius (default 20 km). Available on both desktop and mobile in Advanced and Mobile views. Location permission is requested on first use.
• [TIS2020-3479] – Excluding locations from train search
  Refined the train search panel to only propose locations that have been used in trains, reducing irrelevant location results and improving search accuracy for both current and historical trains.
• [TIS2020-3486] – Prevent deletion of company agreements (set validity end period instead)
  Company agreements can no longer be deleted. Instead, users can expire an agreement by setting its validity end time to the current system time. Expired agreements are displayed in a visually distinct style.
• [TIS2020-3494] – Change retention logic for MESSAGE table
  Reduced the retention period for stored XML messages in the MESSAGE table from 45 days to 14 days. The simplified retention logic improves database performance while still covering the operational need for resending past messages to newly involved companies.
• [TIS2020-3477] – Optimize Outbound Interfaces
  Redesigned the Outbound Interface Overview page with a hierarchical and organized company → queue → interface structure.
• [TIS2020-3500] – Prevent blocking of processing when receiving lots of messages for same train
  Improved message processing logic to detect and automatically recover from worker queue saturation when very high volumes of messages for the same train are received. The system now remains stable and message flow is restored automatically even under excessive load from a single source.
• [TIS2020-3504] – Improve grouping of trains (multiple trains at same location) on map
  Improved the labelling and visual presentation of train groups on the map when multiple trains are located at the same position.
• [TIS2020-3511] – Visibility of registered users
  Added a new "Registrations" page for company administrators, showing the status of users who have not yet completed the full registration process. Statuses include Rejected, Pending Azure, Email Confirmed, and Pending Email Confirmation. Company admins can also delete registration entries to allow users to re-register.
• [TIS2020-3519] – Collect statistics about number of trains sent via interface/queue/company
  Introduced data aggregation for counting the number of trains sent per outbound interface. Data is aggregated daily and monthly for use in reporting.
• [TIS2020-3539] – Retention time for user registrations and expired company agreements
  Added configurable retention periods (default 1 year) for user registrations and company agreement requests based on status (pending, accepted/done, rejected). Removing pending registrations or agreements also removes the corresponding task.
• [TIS2020-3469] – Remove linkable flag of train sections after 24–48h if there is no counter part available
  Train sections that remain unlinked after a configurable period (24–48h) are no longer considered linkable. Previously, sections ending in a linking region retained their linkable flag indefinitely, even when no matching counterpart existed. Removing the flag improves the accuracy of linking statistics by excluding trains that have no realistic linking opportunity.

• [TIS2020-3468] – Intermediate Section Linking
  Fixed an issue where trains were automatically unlinked after receiving running information for an intermediate section. The intermediate section insertion logic has been optimized to prevent incorrect unlinking of previously established train associations.
• [TIS2020-3521] – RFC Layer error messages
  Resolved an issue where users with a previously saved RFC layer received persistent error messages upon login. The error could not be cleared through the UI. Handling of legacy RFC layer selections has been corrected so that invalid saved layers no longer cause errors.
• [TIS2020-3524] – NPE when viewing interruptions
  Fixed a NullPointerException that occurred when certain users navigated to the overview of interruptions.
• [TIS2020-3527] – Company Agreements for a company with location restrictions
  Fixed an issue where a terminal with a location restriction could not see trains covered by a company agreement because the OTN on the relevant section did not fall within the expected range. Train visibility through company agreements now correctly accounts for location-restricted companies.
• [TIS2020-3534] – Authorized Company cannot see 'Add new Agreements'
  Fixed an issue where an authorized company (granted access via "Add new Agreement") could view trains on the map but could not see the corresponding agreement in the Company Agreements menu.
• [TIS2020-3535] – Company page not editable with Edit own Company right
  Fixed a permission issue where company administrators with the "Edit own Company" right were unable to edit their company's page. The page now correctly allows editing for users with the appropriate permissions.
• [TIS2020-3553] – TCRMessage error
  Fixed an error in TCR message processing that caused a NullPointerException when creating interruption notification emails.
• [TIS2020-3550] – Duplicate entries for multiple locations
  Fixed a display issue where certain locations (e.g. in Bern) appeared as duplicate rows (2–3 entries each) on the train detail page.
• [TIS2020-3555] – Red Dot on Incident Management menu
  Fixed an issue where the unread-message indicator (red dot) on the Incident Management menu could not be cleared even after marking all messages as read. The read/unread tracking logic has been corrected.
• [TIS2020-3563] – Wrong date format in the frontend
  Fixed a display issue where dates were shown in American format (MM/DD/YYYY) instead of the expected European format in certain parts of the UI.
