Hi,

I reflashed today my beta Tachyon and it received:

```auto
Tachyon ubuntu 20.04 (headless, NA region)
Version: 1.0.161
[█████████████████████████] 100% | Downloading tachyon-ubuntu-20.04-NA-headless-formfactor_dvt-1.0.161.zip ...

```

While reflashing, also today, my alpha unit:

```auto
Tachyon ubuntu 20.04 (headless, NA region)
Version: 1.0.130
[█████████████████████████] 100% | Downloading tachyon-ubuntu-20.04-NA-headless-1.0.130.zip ...

```

Is this difference normal?

Thanks

Hey **[gusgonnet](https://community.particle.io/u/gusgonnet)**

The alpha units are locked on an older version for the time being - they are still fully functional, its just that we had to move fast on the beta units and so kept alpha (EVT units) at a pinned version.

Hope that helps!

Thanks

Nick.
