I added a Hamilton page here, which hamiltonapp.com now redirects to as well. I’ve linked to my GitHub repository with the current set of open-source code for calculating US Savings Bond values, and a download link for Hamilton 1.1.6.
Hamilton 1.1.6 Posted
First up, in regards to this comment – Hamilton 1.1.6 is now available for download . For now, this will be the last version of Hamilton, and is available for free.
I’m rewriting the internals of Hamilton, the bits that actually calculate the values of your Savings Bonds, and plan to make them available as an open source product that you’ll be free to modify and use as you see fit. From the feedback I received about Hamilton 1.1.x people have a variety of things they’d like to be able to do and ways they’d like to manage their bonds – too many for me to reconcile into a Hamilton 2.0 product alongside the contract development that fills my days at this point.
Stay tuned for more details on the open-sourcing of some of the Hamilton code…
Hamilton 1.1.5 Posted
I just posted Hamilton 1.1.5 with a few minor bug fixes. Unfortunately haven’t made much progress on Hamilton 1.5 lately, just been too busy with work

Hamilton 1.1.4 Posted
Hamilton 1.1.4 is now available for download. It’s a 32-64 bit Universal binary for Mac OS X 10.5 and 10.6. Development slowly continues on Hamilton 1.5, still targeting a release this year – I’m swamped with contract work at the moment!
