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.
-2005.01.11
+2005.03.30
----------
-A fix to some out-of-bounds accesses reported by Milan Tomic (see the comment under `BigUnsigned::divideWithRemainder'). `BigUnsigned::multiply' and `BigUnsigned::divideWithRemainder' implementations neatened up a bit with the help of a function `getShiftedBlock'. I (finally!) introduced a constant `BigUnsigned::N', the number of bits in a `BigUnsigned::Blk', which varies depending on machine word size. In both code and comments, it replaces the much clunkier `8*sizeof(Blk)'. Numerous other small changes.
+Sam Larkin found a bug in `BigInteger::subtract'; I fixed it.
+
+2005.01.18
+----------
+I fixed some problems with `easyDataToBI'. Due to some multiply declared variables, this function would not compile. However, it is a template function, so the compiler parses it and doesn't compile the parsed representation until something uses the function; this is how I missed the problems. I also removed debugging output from this function.

+A fix to some out-of-bounds accesses reported by Milan Tomic (see the comment under `BigUnsigned::divideWithRemainder'). `BigUnsigned::multiply' and `BigUnsigned::divideWithRemainder' implementations neatened up a bit with the help of a function `getShiftedBlock'.

In both code and comments, it replaces the much clunkier `8*sizeof(Blk)'. Numerous other small changes. There's a new conversion routine `easyDataToBI' that will convert almost any format of binary data to a `BigInteger'.
I have inserted a significant number of new comments. Most explain unobvious aspects of the code.
---------
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.
