Yes.

You fetch a newer distribution from www.squid.org, build it like you did
the first time and make some minimal updates to your squid.conf (I think
this is only required if you use proxy_auth)

If you installed a binary distribution the last time then I'd recommend
you to look for an updated binary Squid distribution from the same
pacakger who made the binary package you installed previously.

I always recommended to stay reasonably current unless you have reasons
not to. The current release of Squid for which there will be bug fixes
is currently 2.2.STABLE5(+ a couple of patches). Generally later
releases contains fewer bugs and glitches than earlier versions (with
some exceptions).

Upgrading is not strictly requrired if you don't experience any problems
with your current Squid-2.1 installation. The choice is yours. I also do
not recommend upgrading immediately once a new release comes out if you
have a well working system. Sometimes there are errors in the
distribution, and it is not fun to be the first taking these errors if
you previously had a good working system.

I think you will also effectively loose your current cache if you
upgrade. There has been some changes in how Squid stores it's on disk
objects and I think 2.1.PATCH2 is prior to this change.
