I've reimplemented outline-occur using Xref, so now it is named outline-xref. The reason is that Occur is designed around regular expressions, while Outline supports both regular expressions and custom search functions to find outline headings. If we want to provide a navigable outline that matches the headings identified by Outline, we have to support both search strategies and Xref is better suited for this task.

For more information, see the following commit:

My package outline-occur is now part of GNU Emacs core. Therefore, its source code repository has been archived and is now read-only.

Note that its API changed during integration into core. Please refer to the docstring of outline-occur for up-to-date documentation.

For more information, see the following commits:

• 8a88f3ed5aee "Add `outline-occur' command and `display-buffer-default-alist' variable"
• 9e6f03993b82 "* lisp/outline.el (outline-occur): Autoload."

Outline-occur allows users to navigate the current buffer's outline using Occur. Take a look at its source code repository for more details.
