 ## 1.12.0 (Unreleased)
 
+UPGRADE NOTES:
+
+- On Unix systems OpenTofu now considers the `BROWSER` environment variable as a possible override for the default behavior for launching a web browser.
+
+    If you run OpenTofu in a context where an environment variable of that name is already set, it may cause OpenTofu to now open a web browser in a different way than previous versions would have. Unsetting that environment variable will restore the previous platform-specific behavior.
+
+ENHANCEMENTS:
+
+- OpenTofu now uses the `BROWSER` environment variable when launching a web browser on Unix platforms, as long as it's set to a single command that can accept a URL to open as its first and only argument. ([#3456](https://github.com/opentofu/opentofu/issues/3456))
+
 BUG FIXES:
 
-* `for_each` inside `dynamic` blocks can now call provider-defined functions. ([#3429](https://github.com/opentofu/opentofu/issues/3429))
