 ==========
 These entries tell you what was added, fixed, or improved in each version as compared to the previous one.  In case you haven't noticed, a version number roughly corresponds to the release date of that version in `YYYY.MM.DD[.N]' format, where `.N' goes `.2', `.3', etc. if there are multiple versions on the same day.

+----------
+In BigUnsigned::bitXor, change allocate(b2->len) to allocate(a2->len): we should allocate enough space for the longer number, not the shorter one!  Thanks to Sriram Sankararaman for pointing this out.

 ----------
 I ran the sample program using valgrind and discovered a `delete s' that should be `delete [] s' and a `len++' before an `allocateAndCopy(len)' that should have been after an `allocateAndCopy(len + 1)'.  I fixed both.  Yay for valgrind!
