# v0.2 Release Notes

Release date: 2026-07-02

V0.2 adds the compatibility floor required for a Windows agent-runtime aid: the core scripts must run under both Windows PowerShell 5.1 and PowerShell 7.

## Highlights

- Added GitHub Actions CI on `windows-latest`.
- Added matrix jobs:
  - Windows PowerShell 5.1 through `powershell.exe`
  - PowerShell 7 through `pwsh`
- Added `-PowerShellExe` to smoke and release verification scripts.
- Reworked helper invocations so nested helper calls use the current PowerShell host.
- Fixed JSON shape handling across 5.1 and 7.
- Adjusted timeout smoke tests to avoid environment-specific false failures while still catching process-tree wait regressions.

## Why It Matters

The goal is not to make PowerShell 5.1 and 7 identical. The goal is to give agents a reliable base that detects and avoids known runtime differences before command execution fails.

## Verification

```powershell
powershell -NoProfile -ExecutionPolicy Bypass -File .\scripts\verify-v0.1.ps1 -PowerShellExe powershell.exe
pwsh -NoProfile -ExecutionPolicy Bypass -File .\scripts\verify-v0.1.ps1 -PowerShellExe pwsh
```
