Just a pointer about the deprecated variables in org-ref v3

[zenny]

Hi @sunnyhasija

The configs are getting more matured.

Meanwhile, there are some variables going to be deprecated/removed in org-ref v3 which needs modifications in your configurations. just a pointer!

Warning (:warning): Warning: You are using deprecated variables in org-ref that will be removed in version 3.

The following variables will not be used in version 3:
- org-ref-bibliography-notes
- org-ref-default-bibliography
- org-ref-pdf-directory 

They are replaced by these variables in `bibtex-completion':
- bibtex-completion-notes-path
- bibtex-completion-bibliography
- bibtex-completion-library-path

There are some other changes that are likely to break existing workflows, for example all non-LaTeX exports will be handled by CSL, and all the old export code has been removed.

For more details see https://github.com/jkitchin/org-ref/tree/org-ref-3#readme.

The release date for org-ref version 3 is planned for [2021-10-18 Mon].

Cheers,
