v4.18.0

• The POSHACME_HOME environment variable now supports Windows-style (surrounded by %) environment variable expansion. (#497)
  • So you can set the value to %ProgramData%\Posh-ACME instead of needing to set it explicitly to C:\ProgramData\Posh-ACME for example.
  • NOTE: This requires Windows-style environment variable strings even on non-Windows OSes.
• The Azure plugin no longer tries to re-use cached authentication tokens when using the AZAccessToken parameter set. (#498)
• Fixed a bug with the Azure plugin that broke authentication when submitting multiple orders with different credentials from different tenants. (#498)
• Fixed a problem using Posh-ACME within AWS Lambda due to non-standard dotnet runtime assembly configs. (#418) (Thanks @garthmccormack)
  • This fix involved changing the RevocationReasons enum from a .NET type to a PowerShell native enum.
  • The change constitutes a minor breaking change which makes the enum no longer accessible from outside the module's context, but tab completion and string converted values for the Revoke-PACertificate -Reason parameter work exactly the same as before.
