What’s new in 2.0
Editortech X v2.0 is the biggest update we’ve shipped since launch. We rewrote the editor core for startup speed, rebuilt collaboration on top of a new CRDT engine, and opened up a proper extensions API so AI tooling can plug directly into the editing surface.
Headline changes
- Editor core rewrite. Cold-start time is down 40% on the machines we tested, and typing latency is flat up through 100k-line files.
- Real-time collaboration. Conflict-free shared edits, plus a first-class presence and cursor-sharing layer.
- Extensions API. Third parties can now contribute language features, commands, and AI actions without forking the editor.
Under the hood
The collaboration rewrite is the one we’re proudest of. v1 shipped with a best-effort OT implementation that held up under small teams but got tangled in edge cases when more than a handful of people edited the same file. v2 is built on a CRDT foundation that makes concurrent edits boring — merges always converge, even through flaky networks and long offline sessions.
“Collaboration you don’t have to think about is the only kind that actually gets used.”
For extension authors
The new API surface is contribution-first: instead of patching the editor, extensions declare what they contribute — commands, completion providers, code actions — and the editor stitches them together. There’s a starter template in the docs and a sample AI-refactor extension you can fork today.
What’s next
We’re already working on v2.1: remote pair-programming sessions, a built-in AI assistant contributed through the new extensions API, and a slimmed-down mobile build. Expect an early preview in the coming weeks.
