Some updates create bliss, and others create nightmares.
Once you determine there is an update for your unit(s), search this
site and the internet for problems with it. If the update has been out,
say a couple of months, and you can't find any significant
complaints about it, then you are probably OK to update with it.
I would not recommend installing an update as soon as it
comes out. I've been there, done that, and regretted doing
that.
