OMG! I've been using Mikrotik routers for well over a year now, thought I was always keep them all up-to-date. Today, however, I was poking around on one and noticed a separate section for Firmware updates. I've never done them. Prior to doing this, I just wanted to be sure about any concerns I should have. That is that a major firmware update might have issues or something? Thanks!

Usually there are no issues with the FW upgrade. On the other hand it will not help to anything most probably, especially if your devices are year or so old.
