> Our biggest release yet — rebuilt collaboration, a faster editor core, and a new extensions API designed for AI workflows.


## 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.
