Interestingly, the expiration date was changed in the newest version, but the message is not:

\ifnum\count@>24144 %% (December 2011)
\message{***********************************************************}%%ascii
\message{! YOU HAVE AN OUT OF DATE VERSION OF COMMUTATIVE DIAGRAMS! *}%%

I guess it will never make it to TeX Live due to its extremely restrictive license:

%% COPYRIGHT NOTICE:                                                    %
%%      This package may be copied and used freely for any academic     %
%%      (not commercial or military) purpose, on condition that it      %

%%      included in any published work making substantial use of it.    %
%%                                                                      %

%%      If you are doing something where mistakes cost money (or where  %

%%                                                                      %
%%      You may use this package as a (substantial) aid to writing an   %

%%       (i) you contact me at a suitable time to ensure that you have  %
%%           an up-to-date version (and any infelicities can be fixed), %
%%      (ii) you send me a copy of the book when it's published.        %

So it must not be altered or used for commercial purposes, which is unacceptable for TeX Live. I think the phrase "not altered in any way" includes renaming, so even uploading it to CTAN as diagrams.sty would be illegal.
