This is a crude changelog of the website. Changes will be listed with the date in DDmmmYY format, a description of the change, and a text string that can be used to search for the change on the web page, using your browser's "find in this page" function.

I have not done this sooner because I am doing all this manually, not using any CMS. Translation: this is going to be a real pain in the posterior to keep up to date.
