**Build number: 2026.0.191**

### Improvements

- Added an on-demand option to [delete the local NuGet package cache](https://docs.uipath.com/robot/standalone/latest/admin-guide/command-line-interface#clean-nuget-cache).
- Improved tracing for attended jobs and stopped generating span IDs when tracing is disabled.
- Added the Robot version to execution logs to simplify troubleshooting.
- Improved service discovery reliability and reduced `GetResourceUrl` latency, including scenarios where the same service name exists at both tenant and organization level.

### Bug fix

- Fixed a workflow tracing issue that could throw an `ArgumentException` when an exception had an empty message.
