Acrobat Pro 2021 fully supports PAdES (PDF Advanced Electronic Signatures) , compliant with the EU’s eIDAS regulation. The software allows for certificate-based digital IDs, making it legally binding for contracts. A critical flaw noted in 2021 was a delay in validating revocation status for certain root certificates (CVE-2021-28548), patched in the August 2021 update. adobe acrobat pro 2021

With the 2021 update, Adobe emphasized cloud-native reviews. The Shared Review feature allows multiple users to add comments, highlights, and stamps simultaneously without creating conflicting copies. The “@mention” function, borrowed from Slack/Teams paradigms, integrates directly with Microsoft Teams and Outlook, closing the loop between PDF annotation and corporate communication. | Feature | Adobe Acrobat Pro 2021 |
