JPEG 9 Logo

In January 2018 the Independent JPEG Group released a new version 9c of libjpeg. This version contains numerous improvements in security, performance and stability. Few days after the release a first application ( included the new library into its new version. Other companies announced the use of the library for the next release, e.g. PhotoLine, Directory Opus or StudioLine Photo.

Libjpeg developer Guido Vollbeding: “It is recommended that application developers always integrate the latest release for security and performance reasons. They are also invited to create their own instances on the basis of the reference libjpeg. With this new release we could maintain the anticipated release cycle of two years.” The platform build systems were also updated to the latest status. For the Microsoft Windows system the build system was upgraded to Visual Studio 2017 and Windows 10 SDK.
