What's New in PowerShell 7.6

PowerShell 7.6-preview.5 includes the following features, updates, and breaking changes. PowerShell 7.6 is built on .NET 9.0.101 GA release.

For a complete list of changes, see the CHANGELOG in the GitHub repository.

Updated modules

PowerShell 7.6-preview.5 includes the following updated modules:

  • Microsoft.PowerShell.PSResourceGet v1.1.0
  • PSReadLine v2.4.4-beta4
  • Microsoft.PowerShell.ThreadJob v2.2.0
  • ThreadJob v2.1.0

The ThreadJob was renamed to Microsoft.PowerShell.ThreadJob module. There is no difference in the functionality of the module. To ensure backward compatibility for scripts that use the old name, the ThreadJob v2.1.0 module is a proxy module that points to the Microsoft.PowerShell.ThreadJob v2.2.0.
