Windows 10: PowerShell 7.1.0 RC1 released

Brink · Sep 30, 2020

Known Issues

This release of PowerShell is impacted by a few known regressions and a by-design breaking change in .NET 5.0.0-rc.1.

Given the impact of these regressions, particularly in interactive scenarios on non-Windows systems, we will only be publishing PowerShell v7.1.0-rc.1 packages for Windows and Linux, skipping macOS until v7.1.0-rc.2 is available with the proper fixes.

[Regression] The console API System.Console.TreatControlCAsInput is backwards on Linux and macOS: dotnet/runtime#42423. The fix was made in .NET 5.0.0-rc.2: dotnet/runtime#42432

This causes the Ctrl+c to not work in PSReadLine on Linux and macOS.

[Regression] The console API System.Console.ReadKey() incorrectly returns Ctrl+J for ENTER on macOS: dotnet/runtime#42418. The fix was made in .NET 5.0.0-rc.2: dotnet/runtime#42477

This causes ENTER to not be functional in the PSES integrated console.

[Regression] Performance regression on Linux and macOS: dotnet/runtime#41739. The fix was made in .NET 5.0.0-rc.2: dotnet/runtime#41820

This causes potential performance issues on some specific architectures, Linux distros, and macOS. For instance, the command discovery in PowerShell is up to 20x slower on Ubuntu 18.04 WSL 2.

[By-design breaking change] TLS 1.0 and TLS 1.1 were retired from the default on Linux machines where OpenSSL 1.1 and above is used: dotnet/runtime#40746

This causes Invoke-WebRequest and Invoke-RestMethod to throw AuthenticationException when using TLS 1.0 or TLS 1.1 on Linux machines where OpenSSL 1.1 and above is used.
