The PowerShell team has introduced a new preview version of PowerShell. Here is what to expect in the upcoming PowerShell 7.1 platform, and what has already changed in Preview 6.
The preview release of PowerShell 7.1 includes .NET 5 preview 1. Starting with PowerShell 7.0, devs have shifted to align with .NET’s release and support life-cycle more closely. PowerShell 7.1 is expected to become available within a week or two of .NET 5’s release date of winter 2020 and align with their annual release cadence going forward.

- Improvements made to PowerShell Jupyter Kernel

Finally, PowerShell may get a minimal setup, that only includes the parts of PowerShell needed for your scripts. Not only would it take less disk space, but more importantly, a minimal set of code means less patching and security attack surface.
