In that case, do not update. Emacs and Org-mode are showing gear signs that the development is active, the software is constantly improving, and bugs are constantly getting squashed.

It is in your hands if you want to keep using the same version of org-mode and Emacs, or update to the latest and greatest and fix few necessary backward incompatible changes.

The ORG-NEWS also provide elisp snippets that help quickly make those fixes for you. So if you choose to update, give some time to read through ORG-NEWS.
