Agreed, though that is obvious from the release schedule.
But may not be obvious from the standard documentation that one reads.
How many and which type of people actually closely follow the release
schedule?
So does this mean the copyright has already expired then, since we are in
April 2011?
It doesn't mean copyright immediately expires once you stop updating
the copyright year on your project's official documentation. Copyright
laws are vastly different depending on the country you're in. But what
it does mean is that, as I said above, we care enough to keep a note
of the current year we are active within the Sage project. I'm not
saying we need to update the copyright year for every standard
documentation ever released by the Sage project. Rather, let the year
in which Sage x.y.z is released be in sync with the copyright year as
seen on the Sage standard documentation.
I'm not a lawyer, but I doubt this is legally necessary. I just did a search
of the GCC source tree and find 34235 copyright notices that do not include
the year 2011. Clearly the FSF don't seem to take this matter seriously.
Legally or not, ask yourself: Do the companies that develop
Mathematica, Maple, and Matlab care enough about copyright to actually
keep the latest copyright year in sync with the year in which the
latest versions are released? See for yourself at
http://reference.wolfram.com/mathematica/guide/Mathematica.html
http://www.maplesoft.com/documentation_center/
http://www.mathworks.com/help/techdoc/
and the various downloadable documentation.
I initially thought you were saying in all the source files, which I thought was
excessive, but I can see you are talking of a few files, in which case I don't
see it as a big drain on resources.
I did a search in some of the packages in Mathematica. Clearly Wolfram Research
don't see the need to update these files unless they have changed.
