This release inadvertently raised the minimum Node.js version from v20.0.0 to v20.19.0+, v22.12.0+, v24.0.0+. (This happened via a dependency update.) This probably should have been a breaking (major) change, instead of happening in a patch version, since it prevents using earlier Node.js versions.

After further testing, we found that most of our development dependencies also require these versions, and so it's not feasible for the jsdom project to support earlier Node.js versions. (For example, our testing frameworks will not run on them.) If you need to use such earlier versions, or otherwise are working in an environment which gives related errors such as ERR_REQUIRE_ESM, then please stick with the v26.1.0 release of jsdom. (Noting, of course, that such versions are unsupported, and we will not respond to bug reports opened against them.)
