Note:

1. Known issue about some filesystem cmdlets do not work correctly with long paths, such as Remove-Item, Rename-Item and Set-Location. For details see: #15466
2. PSReadLine 2.2.0-beta1 and 2.2.0-beta2 do not work with this preview of PowerShell due to breaking changes in the prediction interface. The upcoming PSReadLine 2.2.0-beta3 release will resolve this. Use PSReadLine 2.1.0 as the temporary workaround.
