Debian upgrade to Jessie

[Tom Fowle]

Hi all,
finally realized Debian 8.0 Jessie is released.
I see nothing in a quick perusal of the release notes effecting
accessibility,
or anything else i care about, but-----

Using an old 1.3 gig Asus P2b with doubletalk PC internal.

Are there any risks in just doing a straight upgrade from currently
installed recently updated wheezie using 
apt-get upgrade

Should I worry about backing up much, not really anything critical on
the
box.

I use almost entirely command line simple stuff, lynx, links, mutt and
the
like.

Thanks
