I think you're best off to release a new version of the science collection and make it require 5.3 as the minimum version (one that differs from the currently released one only by sorting out this conflict). I'm not sure which version of nan? and infinte? are the right ones, tho.<div>

This isn't a problem, per se, with the code itself, but the<br>
documentation doesn't build in the pre-release because of the<br>
duplicate labels. In a perfect world, I'd just remove all traces of<br>
them from the science collection and documentation, but then (some)<br>
programs that use the science collection would fail for older<br>
versions.<br>
<br>
What is the best way to handle this?<br>
<br>
Should I remove them from the science collection and change the<br>
dependency for the new version to the latest Racket version? Can I<br>
easily do that for a pre-release version? [For example I noticed that<br>
the pre-release version I downloaded on the 20th was 5.2.901.1 and the<br>
one I downloaded today was 5.2.900.1 - at least in the filenames. So<br>
the numbers seem (to me) to have gone backwards.] Also, should I<br>
consider the new release to not be backwards compatible? [I don't<br>
think there would be any breakage of code using it, but there might be<br>
some edge cases I'm not aware of.]<br>
<br>
Should I leave them in the science collection and just change the<br>
documentation to exclude nan? and infinite? on the requires? This is<br>
what I had done previously when they popped up in the plot/utils<br>
module.<br>
<br>
Should the science collection just export the new nan? and infinite?<br>
routines so they are still provided? [That might handle any edge cases<br>
I'm not aware of.]<br>
<br>
I suspect that I will be having more of these as Neil's new math<br>
routines are released. So, I should probably figure out the best<br>
approach that doesn't break anything.<br>
