I have released qpdf version 4.1.0. Packagers take note: this version
of qpdf's make install now installs the libtool .la file since it is
needed by some distributions. If yours does not need or want this file,
you will have to ensure that it is not packaged.
The major enhancement in this version is new API calls for parsing PDF
content streams. I wish to express my gratitude to one of my users, who
has requested to remain anonymous, for suggesting this enhancement,
giving it some very thorough testing on numerous platforms, and making a
generous donation to support its development. The release notes in the
contain additional details on what is new in this version.
