We are announcing the deprecation of building without a configuration file (.readtehdocs.yaml) together with the deprecation of configuration file v1 as well.

Read the Docs will soon start requiring a .readthedocs.yaml configuration file for all projects in order to build documentation successfully. We will stop creating a default configuration file behind the scenes, making assumptions for your projects, and automatically fixing problems with project configurations.

Read the Docs is in the process of migrating our primary marketing website to a single site: https://about.readthedocs.com. The new site offers users more information about our products and their features, in a combined presentation of what was previously divided between two websites (Read the Docs Community and Read the Docs for Business). At the same time, the new site will also serve as a single entrypoint for users that are logging in to Read the Docs accounts. There has been a good deal of confusion around our two sites, and this change makes it more clear which site you’re going to.

Importantly, we are keeping both our Community and Business sites separate for logged in users. There are no changes in our commitment to offering free hosting for open source, or the separation of infrastructure for Business customers.
