+Starting in Chrome 118, the [`isUrlFilterCaseSensitive`](/docs/extensions/reference/declarativeNetRequest/#property-RuleCondition-isUrlFilterCaseSensitive)
+property in the [chrome.declarativeNetRequest](/docs/extensions/reference/declarativeNetRequest/)
+API has been changed to default to `false`. If you wish to keep the old behavior, you can explicitly set `isUrlFilterCaseSensitive` to `true` in
+your declarativeNetRequest rules.
+
+This follows [discussions](https://github.com/w3c/webextensions/issues/269) in the Web Extensions
+Community Group. Firefox and Safari have already implemented a similar change.
