If there a list of changes between 3.1 and 3.0.3 ?
If you have 3.1.0rc installed, look in the HTML help system for the NEWS item. If you don't have it installed, a copy of the nightly news is on CRAN under "new features in this version" on <http://cran.r-project.org/bin/windows/base/rtest.html>. (The actual URL changes sometimes; currently it is <http://cran.r-project.org/bin/windows/base/NEWS.R-3.1.0rc.html>.)
The RSS feed that Ista pointed you to will tell you about changes to that file (i.e. sort of second differences to R).

For example, when using levels(xxxx), if xxxx was not a factor, in 3.0.3 it was changed as a factor but in 3.1 RC it returns NULL. Same for automatic conversion in numeric for characters used in algebric operations. New way is more strict and is better in my point of view. It will prevent unwanted side effect in code.
