This looks to be quite dangerous version. It killed one of my testing devices. I still wonder why all the people massively install every new version without any testing in the laboratory before.
Well, let me explain what can happen in bulk upgrades, or manually working as a robot late at night (not to disturb you clients...)
All networks was running 6.27 and over time we tried some 6.28's, some 6.29's and some 6.30's. Every Time because when you do the auto upgrade sequence (or when you issue een massive script order) the software picks the latest 'current' version.
So what happened with us for instance; We were running now some tenths of units (mainly CPE's) on 6.30.2's to our satisfaction and reading the logs it seems to be pretty stable.
So we started to manually (like a robot a 2 am at night) upgrade whole networks..... only to realize after half an hour the new version was now suddenly 6.31! What? Shit, didn't want that. I'd presumed it still was 6.30.2.
So now suddenly I had some 30 units running on 6.31 but stopped upgrading the rest of the network. Let us wait what happens..... Unfortunately the next morning I found that one rb750UP started with rebooting itself after a couple of hours....
Yes, a unit in production, and yes how stupid. But actually because MT is too confident and therefore too fast by putting the new 'current' version as the proposed new to be used upgrade version.....
We are all humans you know. And people can be triggered to make unwanted mistakes just be following wrong procedures or showing too much confidence in product not ready for real world yet.
Hence we have some profession called "ergonomy" which is the study and development of the knowledge on how to design products (that includes software too!) that can not only do a certain job, but that also avoids us stupid humans to make stupid mistakes....
Hence some of us at times put new softwares on production units while we actually don't even wanted it.....
(Off course, if you did because you just wanted the latest, that even more st......)
