release 2.3.0

Not all links to a node come from another node.  Persisting OLP data
allows us to build backlinks with information about these non-node
headings.

 In this release, we improved the linking process by achieving feature parity between links to files and links to headlines. Before, we used the `file:foo::*bar` format to link to the headline `bar` in file `foo`, but this was prone to breakage upon renaming the file or modifying the headline. This is not the case anymore. Now, we use `org-id` to create IDs for those headlines, which are then stored in our database to compute the relationships and jump around. Note that this will work even if you’re not using `org-id` in your global configuration for Org-mode.

-** Installation Troubleshooting
-*** C Compiler
-Org-roam relies on an Emacs package called ~emacsql~ and ~emacsql-sqlite~ to
-work with the ~sqlite~ database. Both of them should be installed automatically
-in your Emacs environment as a prerequisite for Org-roam when you install it.
-
-~emacsql-sqlite~ requires a C compiler (e.g. ~gcc~ or ~clang~) to be present in
-your computer. How to install a C compiler depends on the OS that you use.
-
-**** C Compiler for Windows
-
-One of the easiest ways to install a C compiler in Windows is to use [[https://www.msys2.org/][MSYS2]] as at the time of this writing:

 * Customizing Node Caching
 ** How to cache

-Org-roam uses a sqlite database to perform caching, but there are multiple Emacs
-libraries that can be used. The default used by Org-roam is ~emacs-sqlite~.

-[[https://github.com/skeeto/emacsql][**emacs-sqlite**]]
-
-The default option used by Org-roam. This library is the most mature and
-well-supported and is imported by default in Org-roam.
-
-One downside of using ~emacs-sqlite~ is that using it requires compilation and
-can cause issues in some environments (especially Windows). If you have issues
-producing the customized binary required by ~emacs-sqlite~, consider using
-~emacs-sqlite3~.
-
-[[https://github.com/cireu/emacsql-sqlite3][**emacs-sqlite3**]]
-
-~emacs-sqlite3~ uses the official sqlite3 binary that can be obtained from your
-system's package manager. This is useful if you have issues producing the
-~sqlite3~ binary required by the other packages. However, it is not recommended
-because it has some compatibility issues with Emacs, but should work for most
-regular cases. See [[https://nullprogram.com/blog/2014/02/06/][Chris Wellon's blog post]] for more information.
-
-To use ~emacsql-sqlite3~, ensure that the package is installed, and set:
-
-#+begin_src emacs-lisp
-  (setq org-roam-database-connector 'sqlite3)
-#+end_src
-
-[[https://github.com/emacscollective/emacsql-libsqlite3/][**emacsql-libsqlite3**]]
-
-~emacs-libsqlite3~ is a relatively young package which uses an Emacs module that
-exposes parts of the SQLite C API to Emacs Lisp, instead of using subprocess as
-~emacsql-sqlite~ does. It is expected to be a more performant drop-in
-replacement for ~emacs-sqlite~.
-
-At the moment it is experimental and does not work well with the SQL query load
-required by Org-roam, but you may still try it by ensuring the package is
