How to Install / Upgrade: Jotai v2.20: Rework Store Building Blocks for High-Throughput Performance and Sets the…

Jotai v2.20.0 reworks internal store building blocks to improve performance in high-throughput scenarios and to address earlier performance regressions. The everyday application API is unchanged. Library authors should note deprecations that prepare the ground for Jotai v3.

Upgrade by installing jotai at version 2.20.0 with your package manager, for example npm install jotai@2.20.0, yarn add jotai@2.20.0, or pnpm add jotai@2.20.0. Lock the version in package.json, reinstall dependencies if your lockfile does not update cleanly, then rebuild and restart your app so the new package is what runs.

Gotchas mainly affect library authors: deprecations in this release matter for code that depends on internal store building blocks, while most app code can stay as it is. Verify by confirming package.json and the lockfile resolve jotai to 2.20.0, running your usual tests and high-throughput paths, and checking the build or test output for deprecation warnings so you can plan fixes before v3.
