Do you have an example of what changed? We haven't really made any breaking changes for quite some time and have been improving on the existing feature set. Smaller bundle sizes with no code changes etc are part of this.
If you take the getting started readme of Next.js 3 years ago it still works today.
Thank you for providing feedback in a friendly way, we're always happy to improve where possible! In case you're curious we have a WIP pull-request: https://github.com/zeit/next-site/pull/159
Thank you for your feedback @Ndymium, we've shipped a new version of the website that has a loading indication (based on the with-loading example posted above)
Just to explain the reason there is a login at all, this is mostly for historical reasons. The original learnnextjs.com built by Arunoda was based on another project he created for teaching Meteor.
Anyway as said we're rewriting /learn, using MDX (http://github.com/mdx-js/mdx) for content and the quizzes will store the result in your browser.
We're not even "rewriting everything in Typescript at once". We're slowly converting files over one by one. No public APIs are changed. Furthermore, we have an extensive test suite of end-to-end tests for both development and production behavior.
The cold-boot problem is an interesting one, it's heavily correlated to the serverless function size, this is why we implemented a complete output target for serverless, to output the smallest possible function that is completely standalone, no dependencies. This makes cold-boot considerably faster. For example on https://next-news.now.sh/ it's hard to tell the difference between cold-boot and warm functions.
In case of Invision it seems like images / render blocking css that was added outside of Next.js are the main culprit. I've reached out to Jon Wheeler who works on the marketing site to make him aware.
As said elsewhere, I mostly act as a curator of a very large effort of hundreds of individuals. The project was actually co-created by several other people who work on infrastructure at ZEIT (e.g..: Naoyuki Kanezawa led all the initial releases, designed important parts of the framework, Arunoda Susiripala contributed the test harness and key build pipeline infrastructure, and so on).
