PowerShell 7.4 LTS
Released: November 2023 | LTS until: November 2026 | Runtime: .NET 8
PowerShell 7.4 is the recommended LTS version for production environments. All operators introduced in 7.0 are fully stable and battle-tested.
Key Features
Stable Operators (Introduced 7.0, Fully Stable in 7.4)
# Ternary operator
$label = ($count -gt 0) ? 'has items' : 'empty'
$env = ($isProd) ? 'production' : 'development'
# Null-coalescing
$port = $config.Port ?? 8080
$timeout = $env:TIMEOUT ?? 30
$name = $null ?? $null ?? 'last-resort'
# Null-coalescing assignment
$cache ??= @{}
$list ??= [System.Collections.Generic.List[string]]::new()
# Null-conditional member access
$city = $user?.Address?.City ?? 'Unknown'
$first = $arr?[0]
# Pipeline chain operators
npm install && npm test && npm run build
git pull || Write-Error "Pull failed"
Web Cmdlet Improvements (7.4)
# New timeout parameters
Invoke-RestMethod -Uri $url -ConnectionTimeoutSeconds 10 -OperationTimeoutSeconds 30
# Brotli decompression support — automatic
$r = Invoke-WebRequest -Uri 'https://example.com'
# Auto-retry on HTTP 429 with Retry-After header
Invoke-RestMethod -Uri $rateLimitedApi # respects Retry-After automatically
# Ctrl+C support when connection hangs — no code change needed
ForEach-Object -Parallel Improvements
# Better error propagation from parallel blocks
# -ThrottleLimit default raised to match processor count
1..100 | ForEach-Object -Parallel {
Get-Process -Id $PID
} -ThrottleLimit 10
ConvertTo-Json Changes (Breaking from 7.3)
# Large enums serialized as numbers (not strings)
[System.DayOfWeek]::Monday | ConvertTo-Json # produces 1 (number), not "Monday"
# BigInteger serialized as number
[System.Numerics.BigInteger]::Parse('999999999999999999') | ConvertTo-Json
PSReadLine 2.3.6
# Predictive IntelliSense
Set-PSReadLineOption -PredictionSource History
Set-PSReadLineOption -PredictionSource HistoryAndPlugin
Set-PSReadLineOption -PredictionViewStyle InlineView # ghost text
Set-PSReadLineOption -PredictionViewStyle ListView # dropdown
# Tab completion improvements
# - Better hashtable key completion
# - Parameter completion respects ValidateRange
# - Enum parameter completion
PSFeedbackProvider (Experimental in 7.4)
Enables "Did you mean Get-ChildItem?" style suggestions for mistyped commands. Graduates to stable in 7.6.
Installation
# Windows (winget)

Migration from 5.1
See the parent powershell/SKILL.md for 5.1 vs 7.x differences. Key points:
- Runtime: .NET Framework 4.x (5.1) vs .NET 8 (7.4)
- Executable:
powershell.exe(5.1) vspwsh.exe(7.x) - Side-by-side: both can coexist on the same system
- Use
Import-Module -UseWindowsPowerShellfor 5.1-only modules

kubectl command-line usage and scripting: kubeconfig and context management, output formats (jsonpath, custom-columns, go-template), all major verbs (get, describe, apply, delete, exec, logs, port-forward, rollout, scale, drain), workload resources, config/storage, networking, RBAC, node management, debugging (CrashLoopBackOff, ImagePullBackOff, OOMKilled), and scripting patterns (dry-run, diff, wait, jq, kustomize). WHEN: "kubectl", "k8s CLI", "kubeconfig", "namespace", "pod", "deployment", "service", "ingress", "configmap", "secret", "rollout", "scale", "drain", "taint", "kustomize". Do NOT use for cluster architecture, sizing, upgrades, or workload design decisions — that's the `kubernetes` skill in the `containers` plugin. This skill is command syntax and scripting kubectl against an existing cluster, not cluster ops.

Covers process management, networking (curl, ssh, rsync, nc), file locking (flock), parallel execution, and production script patterns.

Do NOT use for Azure architecture, landing zones, or multi-subscription strategy — that's the `cloud-platforms` plugin. This skill is about command syntax and scripting the CLI, not deciding what to provision.
