How do I get a new copy of amsart?

Question

According to the comments and answers to Why is LaTeX replacing 2010 for the math subject classification with 1991?, using an old copy of amsart results in a 1991 Mathematics Subject Classification, rather than a 2010 Mathematics Subject Classification.

My question is: Where do I get a new copy of amsart, and how does one install it on OS X? (I already have MacTeX installed.)

Thanks for your help!

I personally would recommend you download the complete TeXLive2014 instead of trying to update one file at a time. For the Mac you can download it from MacTeX-2014 Distribution. — Peter Grill, Nov 04 '14 at 23:21
amsart is available here. (Read the installation instructions to find out how to generate the .cls file.) — ChrisS, Nov 04 '14 at 23:23
@PeterGrill Depending on the age of the Mac, it may not be possible to update MacTeX. — cfr, Nov 04 '14 at 23:51
another way to get the current amsart is to download the amscls distribution from http://www.ams.org/tex/amslatex. this distribution already has the .cls files "unpacked". — barbara beeton, Nov 05 '14 at 20:16

it's not really clear what the problem is here.

amsart was updated in 2009 to accept an option

\subjclass[2010]{...}

there is a large backlog of existing documents that use earlier versions of the subject classification, so versions later than 1991 must be specified as options.

if a new version of amsart is really needed, there are several ways to get it; it is part of the amscls package:

it is included in tex live
it can be retrieved from ctan
it can be downloaded from the ams server
