 ## tip
 
+* FEATURE: vmalert: add `-remoteWrite.disablePathAppend` command-line flag, which can be used when custom `-remoteWrite.url` must be specified. For example, `./vmalert -disablePathAppend -remoteWrite.url='http://foo.bar/a/b/c?d=e'` would write data to `http://foo.bar/a/b/c?d=e` instead of `http://foo.bar/a/b/c?d=e/api/v1/write`. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1536).
