My software has frequent updates. The changelog ontains adequate amount of information about each change (often complete sentences). It's currently more than 100,000 characters long (16,000 words over 1,000 lines) and counting. While it's a lot of data, I like to display it so customers get the message there is a long evolution behind the product.
Currently each update is separated into a few unordered lists (new features, improved, bugfixes, updated libraries).
I'd like something that is fun and also helps navigation in the page, such as a timeline slider (Wayback Machine), vertical timeline (Facebook), table of contents (Wikipedia)... Currently it's just a wall of text. While I know not many people read it, I'd still like to make it as pleasing as possible.
