I got very scared that free users can only create 3 frames in each file, and only 3 files. But this is only for collaboration. If you've been using Figma solo, you can have unlimited frames, this change doesn't affect you.

> Drafts is becoming a personal space for work. In drafts, you’ll still have unlimited files, pages, and viewers. However, if you want to co-edit with others, you have to move the file to a team space.

> In the team space, we’re removing the two-editor limit, which means you'll now be able to collaborate more freely with unlimited editors. In order to introduce unlimited editors for free, we'll be adding a new maximum of three files in the team space. Each file will have a cap of three pages.
