Version 9.26 (2018-11-20)

Highlights in this release include:

  • Security issues have been the primary focus of this release, including solving several (well publicised) real and potential exploits.

    PLEASE NOTE: We strongly urge users to upgrade to this latest release to avoid these issues.

  • IMPORTANT: We are in the process of forking LittleCMS. LCMS2 is not thread safe, and cannot be made thread safe without breaking the ABI. Our fork will be thread safe, and include performance enhancements (these changes have all be been offered and rejected upstream). We will maintain compatibility between Ghostscript and LCMS2 for a time, but not in perpetuity. Our fork will be available as its own package separately from Ghostscript (and MuPDF).

  • Thanks to Man Yue Mo of Semmle Security Research Team, Jens Müller of Ruhr-Universität Bochum and Tavis Ormandy of Google's Project Zero for their help to identify specific security issues.

  • The usual round of bug fixes, compatibility changes, and incremental improvements.
