PowerShell 7.2: What’s New for DevOps

PowerShell 7.2 is the new LTS (Long Term Support) release built on .NET 6. It consolidates the cross-platform story.

ANSI Color Support

PS 7.2 introduces the $PSStyle automatic variable which makes decorating output easier and cross-platform compatible.

Write-Host "$($PSStyle.Background.Red)CRITICAL ERROR$($PSStyle.Reset)"

Parallel ForEach-Object

While introduced earlier, the improvements to ForEach-Object -Parallel in 7.x make it indispensable for DevOps tasks like restarting 50 servers or checking status of 100 endpoints.

$servers | ForEach-Object -Parallel {
    Restart-Computer -ComputerName $_ -Force
