2 Version With the same name

Product: PowerShell Universal

On the site Downloads - Ironman Software we have two downloads
PowerShell Universal 2.3.0
PowerShell Universal 1.5.21
they both have Linux, Windows files.

Why do we have 2 and what should I pick for my production environment


2.3.0 is the new major version of PU. New features will be added here. I would pick 2.3.0 for prod

Thank you for your reply, but it does not explain the main question.

Why on the site we have 2 application with the same name.


We are maintaining 1.5 for 6 months after the 2.x release since there were breaking changes. We still have customers running 1.5.
