Well, this is something that has been bothering me for a long time. I find the changelog messy. Initially, Kagi started just as a search page, so the changelog was fine. Many services were added over time: assistant, maps, translator, news, Kagi Mail in the coming months, and other features that will come later. Keeping everything in the changelog as it is will become a mess in my opinion; it's already becoming one.
It's purely an aesthetic issue to make it more organized and separated by products. To help you better understand what I'm talking about, take a look at the Fastmail blog and imagine Kagi's products separated. For example: Kagi Search, Kagi News, Kagi Translate, Kagi Mail, etc. Each section containing two pieces of information. This would be much more organized than simply putting all the products' changelogs on the same page.
When we go to email sites like Fastmail, Protonmail, Tutamail, Startmail, they have a blog section divided into categories that talk about changes to their products, security & privacy, notes, etc. Now, Kagi only has a changelog to list changes and updates for various products, which ends up making the page messy with information from different products, making it difficult to find a change for a specific product.
