Walkthrough

The changes update the minimum supported Node.js version from 18 to 20 across documentation, CI workflows, Docker configuration, TypeScript, and build tooling. Code previously accommodating Node.js 18 polyfills is removed. Build and test targets are updated to ES2023 and Node.js 20/22. Minor internal symbol changes improve timeout error identification.

Changes

File(s)	Change Summary
.github/workflows/meilisearch-prototype-tests.yml .github/workflows/pre-release-tests.yml .github/workflows/tests.yml	Node.js 18 removed from test matrices; integration tests now run only on Node.js 20 and 22.
CONTRIBUTING.md	Updated minimum required Node.js version from 18 to 20 in the development requirements section.

Poem

🐇
Goodbye to Node 18,
Now 20’s on the scene!
Tests and builds are shiny new,
With ES2023 in view.
Crypto’s clear, the code is tight—
This rabbit hops with future’s light!
