# New Functionality and Changes Introduced with Xpress Workbench 3.0

This section describes the new features and changes introduced with Xpress Workbench 3.0

Xpress Workbench version 3.0 includes the following changes and new features:

- Support for Mosel 5 and Insight 4.50
- New module browser sidebar shows all Mosel modules and their exported symbols.
- Inline documentation is now shown when autocompleting symbols from Mosel modules.
- Improved autocompletion of Mosel statements.
- Mosel models can now be run in trace mode.
- When compiling a Mosel model, the directory where bim files are created can now be specified.
- When connecting to Insight over HTTPS, certificates from the OS keystore are now used to verify the server.

Fixed in this release:

- Updated Mosel model would not be published to Insight if a .bim file already existed.
- Debugger would not connect if the Workbench window was too narrow.
- Directories within a Workbench project could be deleted or renamed when the project was open.
- Fixed an issue on macOS where Mosel models cannot be run when the project path is too long.
- Error messages printed by sub-models were not displayed when the master model was run in Workbench.
- Interrupting an Insight debug session would leave the scenario executing until manually cancelled from the Insight job queue.
