# Nylas React SDK v3.1.4 and Web Elements v2.4.0

Source: https://developer.nylas.com/docs/changelogs/2026-02-24-javascript-nylas-react-v3-1-4/

## Added

- **Async participant search in the Scheduler Editor.** Pass a `participantSearch` callback (`participant-search` attribute) to `<nylas-scheduler-editor>` to fetch participants from your own API as organizers type, instead of listing every option up front in `additionalParticipants`. See [Search participants from your own backend](/docs/v3/scheduler/using-scheduler-editor-component/#search-participants-from-your-own-backend).

## Updated

- Upgraded `@nylas/web-elements` to v2.4.0.

## Fixed

- Fixed a regression where `<nylas-scheduling>` required a session ID for public Configurations that use `configurationId`. Validation now waits until the auth props are set.
