I've made the upgrade from 2.2 to 2.3.8. The upgrade went pretty smoothly with the exception of some minor CSS modifications, and the site seems mostly functional with the exception of the following issue:
The abstract and pdf links only work for the first record in each issue, present and archived. So if you click on the first title on any of the issues, you will get the corresponding pdf or abstract. However, if you click on any other title, it will take you back to the landing page. Note:
when you mouse over the link, you see the correctly url.
