 Change Log
 ==========
 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.
 
+2007.02.13
+----------
+Boris Dessy pointed out that the library threw an exception on "a *= a", so I changed all the put-here operations to handle aliased calls correctly using a temporary copy instead of throwing exceptions.
+
+2006.08.14
+----------
+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.
+
+2006.05.03
+----------
+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!
+
+2006.05.01
+----------
+I fixed incorrect results reported by Mohand Mezmaz and related memory corruption on platforms where Blk is bigger than int.  I replaced (1 << x) with (Blk(1) << x) in two places in BigUnsigned.cc.
+
+2006.04.24
+----------
+Two bug fixes: BigUnsigned "++x" no longer segfaults when x grows in length, and BigUnsigned == and != are now redeclared so as to be usable.  I redid the Makefile: I removed the *.tag mechanism and hard-coded the library's header dependencies, I added comments, and I made the Makefile more useful for building one's own programs instead of just the sample.

 ----------
 A few tweaks in preparation for a group to distribute the library.  The project Web site has moved; I updated the references.  I fixed a typo and added a missing function in NumberlikeArray.hh.  I'm using Eclipse now, so you get Eclipse project files.

 After months of inactivity, I fixed a bug in the `BigInteger' division routine; thanks to David Allen for reporting the bug.  I also added simple routines for decimal output to `std::ostream's, and there is a demo that prints out powers of 3.
