7.1.0-rc.1 - 2020-09-29

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.
