fix(deps): mark support for `react<19.2` and `@sanity/ui<3` as deprecated #11238

bjoerge · 2025-11-24T15:26:48Z

Description

This marks React < 19.2 as deprecated, which will issue a warning when running sanity dev from now on:

> sanity dev

[WARN] The following package versions have been deprecated and should be upgraded:

  react (installed: 18.3.1, want: ^19.2)
  react-dom (installed: 18.3.1, want: ^19.2)

Support for these will be removed in a future release!

  To upgrade, run either:

  npm install "[email protected]" "[email protected]"

  or

  yarn add "[email protected]" "[email protected]"

  or

  pnpm add "[email protected]" "[email protected]"


Read more at https://docs.sanity.io/help/upgrade-packages

✓ Checking configuration files...
✓ Starting dev server
Sanity Studio using [email protected] ready in 254ms and running at http://localhost:3333/

Note that React 18 is still supported, and will be so for the remaining releases on the 4.x line.

Remaining tasks

The linked help article needs updating
Publish a blog post outlining why we're doing this

What to review

The warning feels a bit heavy-handed to me. It's only deprecated after all. Should we change wording and/or offer a way to silence it?

Testing

Follow instructions to install preview build in an existing studio. Make sure react and react-dom versions are in the 18.x range. Observe the deprecation warning appear.

Notes for release

TBD

📚 Glossary

column definitions

benchmark — the name of the test, e.g. "article", followed by the label of the field being measured, e.g. "(title)".

latency — the time between when a key was pressed and when it was rendered. derived from a set of samples. the median (p50) is shown to show the most common latency.

p75 — the 75th percentile of the input latency in the test run. 75% of the sampled inputs in this benchmark were processed faster than this value. this provides insight into the upper range of typical performance.

p90 — the 90th percentile of the input latency in the test run. 90% of the sampled inputs were faster than this. this metric helps identify slower interactions that occurred less frequently during the benchmark.

p99 — the 99th percentile of the input latency in the test run. only 1% of sampled inputs were slower than this. this represents the worst-case scenarios encountered during the benchmark, useful for identifying potential performance outliers.

blocking time — the total time during which the main thread was blocked, preventing user input and UI updates. this metric helps identify performance bottlenecks that may cause the interface to feel unresponsive.

test duration — how long the test run took to complete.
