My apologies if this is answered somewhere searching does not work.
My Pi3 is currently running the jessie SD image v2.1-5. I am wondering if I wget the 3.0.2 release, and make install will it break things badly, or is this the method we can take. I would rather not reimage the SD as there are quite a few customizations I have made and other feeders that are running nicely on it as it is. apt-get is not pulling any updates past 2.1-5, and all of the debian stuff is already on the latest.
