Hi!
For all those who would like to execute massive software update (/system packages update install) and after that massive firmware upgrade (/system routerboard upgrade (and reboot)) on your MikroTiks, now we have a solid solution.
I run a network of free public hot-spots in Slovenia called wlan.novagorica.eu and I have wanted a solution to upgrade all routers with a single click. My programming skills are not that good so my code was rewritten and upgraded by my colleague Miha (who also loves MikroTik devices) and he decided to make it open source, published on GitHub with distributions for Windows, Mac and (not yet 
) Linux.
Software is quite simple - you need to put a list of IP addresses of your routers, insert username and password and SSH port - software uses SSH to execute commands. It will make simultaneous connections to your routers so they will get updated quickly. After couple of minutes you can check if routers are back and then you can run firmware update and reboot command.
So you can download AutoMasshTik and use it for free. With Miha we will try to implement also some new features in the future.
It looks like the example below - and it is really straight-forward to use.
