This is qpdf version 11.4.0. This release contains a few minor enhancements and bug fixes. Highlights include improving annotation flattenening to avoid losing annotations in certain technically incorrect but otherwise usable PDF files, and an enhancement to --optimize-images that allows it to traverse into form XObjects. This release also corrects a packaging error that was causing the MinGW DLL to be about 12 times larger than necessary.

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.

This is qpdf version 11.2.0. There are a few bug fixes and minor API enhancements from 11.1.1. This version also fixes a significant performance bug affecting openssl 3.0.x. This bug was causing poor performance with the Windows executables, which should be noticeably faster in this version.

This is qpdf version 11.0.0. This is a major release with lots of changes. 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. Here are some release highlights:

• qpdf JSON v2 -- a complete, unambiguous representation of PDF file contents using JSON with bidirectional conversion between PDF and JSON
• the build now uses cmake
• PointerHolder has been replaced by std::shared_ptr
• Many performance improvements
• Better memory safety for QPDFObjectHandle objects associated with destroyed QPDF objects
• A new logging facility that enables more reliable output/error redirection for library users

This is qpdf version 10.6.3.0cmake1. It is identical in functionality and binary compatible with 10.6.3. The only changes are

• The old autoconf + home-grown Makefile-based build system has been replaced with cmake
• For Windows, releases contain additional files (examples, static libraries) and executable installers are available in addition to zip files
• The documentation has been substantially updated to describe the new build system. In particular, see
  • Building and Installing QPDF
  • Notes for Packagers
  • Converting From autoconf to cmake

This is a pre-release. Who should test it out?

• There are no functionality changes, so if you're just using qpdf, there's no need to take this release.
• If you packager qpdf for a distribution or build it yourself as part of a larger system, you can use this to migrate to cmake.
• If you are a Windows developer who has been having problems using the DLL from another language, you can try with this release and see if it helps. It's possible that the way cmake builds may resolve some issues that have so far remained elusive.

This release includes a few significant changes:

• All functionality previously available only from the qpdf CLI has been exposed to the library using a new QPDFJob API, which includes fluent interfaces as well as a JSON format that's equivalent to qpdf's command-line arguments.
• Many new interfaces have been added to QPDFObjectHandle and the C API to allow more convient ways querying types and accessing object values in a more type-safe fashion.
• qpdf --help has been revamped so that help is divided into categories, and help is available for each option
• The Running qpdf section of the manual has been rewritten. The manual now includes an index of command-line arguments.

In qpdf 11, PointerHolder will be replaced by std::shared_ptr in QPDF's API. A backward-compatible PointerHolder API will be available. See Smart Pointers for details including things you can do now to prepare. See also comments in PointerHolder.hh.
