Note that syntax higlighting is [currently broken](https://github.com/gorhill/uBlock/commit/01b1ed9a982965378d732ab0cb4bcd68727fe910).
 
+Starting with [1.46.1b15](https://github.com/gorhill/uBlock/commit/81498474d6d440b032681aa9952d593749b39efb), you can use regex-based values as target domain for static extended filters. Example of usage: `/img[a-z]{3,5}\.buzz/##+js(nowoif)`. Use sparingly, when no other solution is practical from a maintenance point of view -- keeping in mind that uBO has to iterate through all the regex-based values, unlike plain hostname or entity-based values which are mere lookups.

 - With the introduction of HTML filtering, the `script:contains(...)` is now deprecated and internally converted into an equivalent `##^script:has-text(...)` HTML filter. The result is essentially the same: to prevent the execution of specific inline script tags in the main HTML document. See [_"Inline script tag filtering"_](./Inline-script-tag-filtering) for further documentation.
