Stop the presses! 
exactly that, no big changes at all.
rb153 is not crashing anymore with certain cards for us after 2.5 upgrade …
that was a RouterOS improvement, as far as I know. not firmware
I have been looking for firmware upgrade proceedures.
Curently I am showing 1.11-1.12 version on my RB532 boards. Upgrade to version 2.5 is available.
Are there any gotchas about doing the upgrade from the terminal window? How long does the upgrade take?
‘system routerboard upgrade’ and reboot the router to complete upgrade, than firmware will be upgraded. Upgrade does not take a lot of time.
