 * fix(sdk-trace-web): fix invalid timings in span events [#4486](https://github.com/open-telemetry/opentelemetry-js/pull/4486) @Abinet18
 * fix(resources): ensure BrowserDetector does not think Node.js v21 is a browser [#4561](https://github.com/open-telemetry/opentelemetry-js/issues/4561) @trentm
+* fix(core): align inconsistent behavior of `getEnv()` and `getEnvWithoutDefaults()` when a `process` polyfill is used [#4648](https://github.com/open-telemetry/opentelemetry-js/pull/4648) @pichlermarc
+  * `getEnvWithoutDefaults()` would use `process.env` if it was defined when running in a browser, while `getEnv()` would always use `_globalThis`. Now both use `_globalThis` when running in a browser.
