+New in [1.46.1b0](https://github.com/gorhill/uBlock/commit/b6981877ba8f9011292aee9556c4d4c08c1bfd2d).

+Ability to filter network requests according to their HTTP method.
+
+This option supports a list of `|`-separated lowercased method names. Negated method names are allowed. 
+
+These are valid methods:
+
+- `connect`
+- `delete`
+- `get`
+- `head`
+- `options`
+- `patch`
+- `post`
+- `put`
+
+As per DNR's own documentation:
+- https://developer.chrome.com/docs/extensions/reference/declarativeNetRequest/#type-RequestMethod
+
+Example:
+```
+||google.com^$method=post|get
+||example.com^$method=~get
+```
+
+The logger shows the method used for every network request. It's possible to filter the logger output for most-common methods: `get`, `head`, `post`.
