The latest version of Nitro PDF Professional (5.3.2) was released last week, and contains some new functionality along with a number of bug fixes. We recommend that all existing users upgrade (free) to the latest version.

New with this release is Certify document (see under Secure and Sign ribbon). A document is certified through the application of a certifying digital signature. This allows the author of a document to:

• Attest to the authenticity of the document contents.

• Select what changes recipients are able to make to the document without invalidating the certification. If an unpermitted change is made, the signature will be represented as being invalid so the recipient knows the document has been altered without permission of the author.
