# Preserve operations for collaborative document edits

**Version:** v2.17.0

**Published:** July 16, 2026

This release adds an opt-in way to send and receive patch operations directly, so collaborative editors, starting with Portable Text, don't lose edits when two clients change the same field at once. This is a core `@sanity/sdk` change. If you use `@sanity/sdk-react`, nothing changes for you here.

## Send patches without diffing

Pass `preserveOperations: true` to `editDocument()` to forward your patches to the server as-is, instead of re-deriving them from a diff. Keyed array operations stay addressable, so concurrent edits interleave instead of overwriting each other.

**index.ts**

```
import {editDocument} from '@sanity/sdk'

editDocument(doc, patches, {preserveOperations: true})
```

Existing calls to `editDocument()` are unaffected.

On the read side, `applyRemoteDocument` now emits a `remote-patches` event with the transaction's patches and an `origin` of `'local'` or `'remote'`. If a preserved patch can't reapply during a rebase, the transaction is skipped and surfaced as a `rebase-error` event instead of failing the store.
