Improvements

• TUN-6560 - Redesigned the Track Engine architecture to improve resource and thread contention on a heavily loaded system. This resolves the issue where the TE disconnects from the MS due to thread starvation when running multiple trackers locally. This issue is less likely to be seen on systems using OBTs, however this change may reduce some of the network latency which results in spurious time sync warnings.

• TUN 6560 - Increased the messaging timeout to ensure that any unusual spikes in resource use do not cause a communication disconnection.

Fixes

• TUN-6556 - Fixed an issue when installing a Management Server without any other services which resulted in it being unable to start due to the data folder being unavailable.

New Features

• TUN-6388 - Added new health check that monitors track output from each radar to identify any that have dropped to zero whilst other radar continue to generate tracks. Details on the feature can be found here https://navtechradar.atlassian.net/wiki/spaces/TUN/pages/783745334/Track+Engine+Configuration#ClearWay%E2%84%A2-Tracking-Performance-Health.

• TUN-6397 - Added new OpenWeather plugin that checks the online service to analyse the weather state from the nearest weather station to the configured ClearWay™ site. The plugin supports the ability to change tracking performance profiles in response to changes in weather state. Document can be found here .

• TUN-6480 - MongoDb database authentication is now supported. This allows database access to be secured with a username and password. Both the database and ClearWay™ must be configured correctly to support authentication. Full instructions on implementing this feature can be found here . Authentication is not enabled by default, so this version will behave like all previous versions.

• TUN-6485 - The underlying .NET framework has been updated to the latest .NET 8 release. This platform offers both security and performance enhancements. This new framework is an evolution of .NET 6 which was introduced in version 4.12. There are no changes to the pre-requisites because these are all included with the normal installation / upgrade.

• TUN-6161 - The SightLogix 533-030 camera has now been integrated. Currently this is based on experimental camera firmware so is not production ready.

Improvements

• TUN-6377 - Improved exception logging for the tracker upgrade manager to include the IP address of the device being upgraded.

• TUN-6239 - Improved manual radar log capture UI notification to indicate if a capture was unsuccessful on any given radar.

• TUN-6383 - The Web Client UI now supports a splitter to enable users to adjust the relative space allocated to both the schematic and the bottom information panel.

• TUN-6422 - When using the OpenWeather service plugin, the current weather state, wind speed, temperature and weather station location will be displayed in the plugin configuration panel.

• TUN-6423 - When using a weather service plugin, there is now a user option available to display the current weather state and temperature in the application’s main title bar.

• TUN-6445 - Improved the alarm categories so the tracker health performance alarm message is more meaningful.

• TUN-6447 - Security has been improved on the Web Client UI to ensure it can’t be opened in an iFrame. This prevents scenarios where the client can be inserted into another application / site.

• TUN-6476 - Security has been improved on the Web Client web server and on the application inter-process communications. All certificates have been updated to use the latest, more secure cryptographic hashing algorithms, Where available all connections will use TLS1.3 but no lower than TLS1.2.

• TUN-6478 - Security has been improved on the Web Client UI to prevent the browser remembering previous usernames in the login dialog. This will forces users to always manually enter their username and password.

• TUN-6480 - Updated MongoDb to version 4.4.28. This version supports improvements to replication including a more efficient synchronisation method and a recovery mechanism that allows initial synchronisations to resume in the event of a minor network interruption.

• TUN-6485 - Security has been improved by updating all dependent packages which at the point of release has resolved all known vulnerabilities in these dependencies. This has also brought all the packages inline with the latest .NET 8 technology stack.

Fixes

• TUN-6396 - Fixed an issue with the tracking area list in the channel which was allowing multiple entries to be selected and removed which resulted in an exception. The logic has been changed to only allow a single entry to be removed at a time.

• TUN-6411 - Fixed an issue where an incorrectly formatted CSV file caused the radar import feature to lock up.

• TUN-6464 - Fixed issue manipulating lane nodes when stacking lanes on top of one another on the carriageway. The top node can now always be manipulated.

• TUN-6509 - Fixed the Track Correlation query to ensure it works with both lost and stale tracks. This overcomes issues when track correlation is being used.

• Fixed the log rotate script which is installed as a Windows Scheduler Task on all database servers. This now works as expected and also supports database authentication. Due to complications with updating the previous script, this updated version will install as a new task and the old task will be removed. Please refer to the for further information on how to implement authorisation with this scheduled task.

• Fixed the process checker for Helvellyn - this now correctly enforces the restriction that only a single UI can be run on the same physical system even if multiple users are logged in concurrently.

• TUN-5995 - Added the ability to copy a TA configuration to one or more sections.

• TUN-6160 - Integrated the Videotec NXPTZ2V8XR camera.

Improvements

• TUN-5510 - Added the ability to raise system alarms in the event that the Track Engine encounters a high number of disconnects from a tracker within a specified time frame.

• TUN-5602 - A new Windows Task Scheduler script is added by the installer on all database servers. This script will force a log rotate on the database every 24 hours.
