 # Changelog
 
+## 2.1.1
+
+### Fixed
+
+- `Invoke-MgxRequest` threw `FileNotFoundException` for `System.IO.Pipelines, Version=10.0.0.0` on hosts whose PowerShell 7.6 payload does not carry that assembly, such as the Azure DevOps `windows-2025-g2` image and Microsoft's Linux container images, which unpack PowerShell over a separately installed .NET runtime.
+
 ## 2.1.0
 
 Merges upstream `gromedev/mgx` 2.1.1. The module name, version line, target framework and CI remain this fork's.

+v2.1.1
+- Fixed Invoke-MgxRequest failing with a missing System.IO.Pipelines assembly on PowerShell 7.6 hosts that do not ship it.
+
 v2.1.0
 - Added Get-MgxContent, downloading file and media content whole or by byte range.
 - Added adaptive request pacing, on by default, spacing requests per workload ahead of the token bucket. Opt out with Set-MgxOption -NoAdaptivePacing.
