Grants.gov made this announcement yesterday. Great progress!
Grants.gov now supports the latest version of Adobe Reader (8.1.1), which is available for free download from the Adobe Website http://www.adobe.com/products/acrobat/readstep2.html. Grants.gov continues to support Adobe Reader version 7.0.9. Only these two versions should be used when submitting grant applications. Other Adobe Reader versions are not supported.
Grants.gov is currently in the process of updating our website to reflect the latest version of Adobe Reader 8.1.1. This update will include the download software page, FAQs and associated text. We will inform you once the site update has been completed.
