React in particular puts out a point release with breaking change warnings, along with an upgrade guide, several months before the next major version so that developers have plenty of time to prepare for any required changes. (For React 19, this was the 18.3 release at the end of April 2024.) They also try to provide scripted code updates ("codemods") to ease the upgrade process. This is admittedly rare in the JS ecosystem.
