QPDF 이전 버전 및 전체 버전

This is qpdf version 12.4.2. In addition to a few small bug fixes, this release features two significant improvements：inclusion of several new binary platform releases and substantial improvements to linearization. We now include official release binaries for MacOS (intel and arm64), Windows arm64, and Linux aarch64 (arm64) both as an AppImage and as stand-alone binaries. For linearization, for certain types of files, qpdf is vastly more memory efficient (we've seen 30× improvements in some cases) and slightly faster. Also, there are a few small fixes to linearization object ordering, so linearized output may differ for some rare files relative to previous releases.

This is qpdf version 12.1.0. This release features a number of small bug fixes and feature enhancements including new CLI flags --remove-structure and --jpeg-quality for helping to create smaller PDFs. 12.1 is planned to be the last minor release to build with C++-17. We plan on requiring C++-20 starting in 12.2.

This is qpdf version 12.0.0. This release has no functional changes beyond a few small bug fixes. This release includes minor breaking changes to ABI (binary interface) and API (source interface) to remove some deprecated functions, improve efficiency, and set the stage for future enhancements. Most code will not be affected, and all the changes have easy fixes that are documented in the release notes. If you are updating your code from a version earlier than 10.6.0, you will have to deal with the PointerHolder transition. If you ran version 11 and are already setting POINTERHOLDER_TRANSITION to 4, you can remove that. A full discussion can be found in the manual in the Smart Pointers section. This version of qpdf still builds with C++-17 compiler, but we will be switching the minimum version to C++-20 soon, but no earlier than April 2025.

This is qpdf version 11.10.0. This release is mostly accumulated fixes and minor improvements. Several improvements were made to qpdf's ability to recover broken files, and several long-standing but minor bugs were fixed. Notable enhancements include allowing qpdf to be built with the zopfli library (slow but good compression) and the addition of --remove-metadata and --remove-info options.
