 - Fixed search highlighting the wrong line. [#10468](https://github.com/sourcegraph/sourcegraph/issues/10468)
 - Fixed an issue where searches of the form `foo type:file` returned results of type `path` too. [#17076](https://github.com/sourcegraph/sourcegraph/issues/17076)
 - Fixed queries like `(type:commit or type:diff)` so that if the query matches both the commit message and the diff, both are returned as results. [#16899](https://github.com/sourcegraph/sourcegraph/issues/16899)
+- Fixed a nonexistent field in site configuration being marked as "required" when configuring PagerDuty alert notifications. [#17277](https://github.com/sourcegraph/sourcegraph/pull/17277)
