I bumped into this today: http://changelog.nomadlist.com/
Another example from a WordPress plugin:
As far as software developers are concerned it’s not so much a changelog as it is a timeline of noteworthy feature additions, but whatever you call it, it’s pretty neat!
The basic idea is that you’d have a category or a tag dedicated to topics that cover a feature release. From there, I can think of many ways in which this could be implemented:
Feed content to a static site generator
Probably the most cost-effective method. Could be hosted on GitHub pages, but would still require a script to be run regularly to grab the content.
Pull in and display content in a single-page application
Could still be done very cheaply through a service like Netlify for instance.
Plugin that creates a custom index page for Discourse
This might stand a chance of being put to use here on Meta (e.g. 301 Moved Permanently), but it’s probably also the hardest one to do. Requires handlebars magic.
