Got two RB750s (amongst other things) here in the office. Saw 4.4 was out and decided to upgrade.

The backup 750 (i.e. the one we keep on the shelf ready for a disaster) upgraded from 3.29 to 4.4 with no problems what so ever.

The main 750 (running 4.2) refused to reboot after the upgrade.

It also refused to reboot after a factory-reset.

I ended up having to do a NetInstall on it before it sprang back into life.

Let this be a warning to you!

I have updated 2x RB750, 1x RB433, 1xRB433UAH, 1x RB600 and 1x x86 (soekris net5501) from 4.2 to 4.4 and no problems so far.

does anyone know if any new changes or bug fixes to the usermanager?

user manager beta-test package is not yet released

Also updated a Crossroads (no problem at all) and a RB411 which didn't come back until it was power-cycled.
