5.9.0 — Pester 5 enters maintenance mode

With the release of Pester 6.0.0, Pester 5 moves into maintenance mode: critical bug fixes and security updates only, no new features.

Narrowed tested PowerShell versions

Pester 5 is now tested only on the PowerShell versions Microsoft still supports:

  • Windows PowerShell 5.1
  • PowerShell 7.4 (LTS) and above

CI coverage for Windows PowerShell 3.0/4.0 and PowerShell 6.2 — all end-of-life per the PowerShell support lifecycle — has been removed. The module manifest keeps its existing minimum version rather than requiring 5.1, so Pester should still load on older PowerShell versions, but those versions are no longer tested; if you run Pester 5 there, you are responsible for verifying it yourself.
