[2.1.2] - 2026-05-26

Changed

• CI workflows migrated to PowerShellOrg reusable CI and release
  workflows (#457)

Fixed

• AddContent path separators normalised to forward slash on PS5.1 —
  Get-ChildItem -Name returns backslash-separated paths on Windows
  PS5.1, causing cross-platform inconsistencies in source/destination
  attributes
• Resolve-ModuleVersionString returned [System.Version] on PS5.1
  because [System.Management.Automation.SemanticVersion] is PS6+
  only; adds a C# shim that defines the type at module load time
  (#463,
  closes #460)
• New-PlasterManifest emitted xmlns inline on PS5.1 — .NET XML
  serializer ignores XmlWriterSettings.NewLineOnAttributes for
  namespace declarations; output is post-processed to normalise
  formatting
  (#464,
  closes #461)
• Get-Culture -Name is PS6+ only; replaced with
  New-Object System.Globalization.CultureInfo in tests
  (#462,
  closes #459)
