Summary
Resolves #8578
This PR removes React 16 from
peerDependenciesand removes related CI steps running tests against React 16 environments.Why are we making this change?
React 16 reached end-of-life over 4 years ago and no actively maintained projects still use it with modern versions of
@elastic/euiinternally.Impact to users
This change doesn't break EUI compatibility with React 16, however, due to dropped support, no further changes will be tested against React 16.
Please upgrade to a modern version of React. If you can't do it immediately, consider v106.0.0 the last EUI version compatible with React 16.
