Release Overview

This release brings significant enhancements, new features, breaking changes, and dependency updates. Please see the Special Note and Breaking Changes for important notices about this release.

Special Note

We are releasing version 4.0 with four known bugs, two of which are fully related to the Project Manager. The Project Manager is turned off by default, so we hope this impact is minimal. We are actively working on the bug fixes and hope to have a 4.0.1 patch sooner than later. See below for more details on the bugs:

  • #4048 The path_selector widget continues to spin even after the directory options are shown. The impacted applications are batch connect apps, such as VS Code, and the Project Manager.

  • #4052 The Project Manager template creation is broken. Only when creating a project from a template do issues arise. Creating a new project works as expected.

  • #4053 The Project Manager icon picker is broken when creating a new project.

  • #4056 The batch connect cards incorrectly display cores. For example, if a user submits a 4 core job, the job will run with 4 cores as selected, but it will only display 1 core. As a reference point for impact, we received one OSC support ticket from our hundreds of users.
