How it has lived

  1. Release 2.2.1 published

    Release 2.2.1 was published on 2026-10-09. It is a Godot load fix on an unchanged format. Text grammar 1.0 stays frozen. npm, the Swift tag, and crates.io threemd are 2.2.1.

  2. Added to this roadmap

    3md joined the public record from its page. Swift, TypeScript, and Rust pass the shared text contract. The viewer can open a document, rotate its cubes, and paint a slice. Sculpt.3md stays a separate app with no packaged download. Quill, atlas, and agent.3md stay off this list.

  3. Make, in the door

    The visit door has a Make shelf of 3md documents in the site viewer, including sculptures and small games. A document with no cube grid opens in Preview instead of an empty Cubes pane. Sculptures that have cubes still open in Cubes.

Latest published update

3md is a plain-text format for documents with depth, with libraries and a viewer on this site. Release 2.2.1 was published on 2026-10-09. npm, the Swift tag, and crates.io threemd are 2.2.1. Text grammar 1.0 stays frozen. Swift, TypeScript, and Rust pass the shared text contract. The release includes the Godot 4.7 addon. The viewer can open a document, rotate its cubes, and paint a slice. Sculpt.3md is the Mac app for this format, and that app is still in development with no packaged download.

What’s next

Keep the libraries and the site viewer current. Sculpt.3md remains a separate app with no packaged download.
