This is qpdf version 11.3.0. The main feature of this release is more substantial performance improvements from M. Holger. This release may run as much as 30% faster than 11.2.0 and also uses less RAM. A new flag --remove-restrictions has been added to invalidate digital signatures and associated restrictions to make a signed file editable (invalidating the signature, of course). There are also a few fixes. For a full list of changes from previous releases, please see the release notes. See also README-what-to-download for details about the available source and binary distributions.
