On May 11, 2022, we released version 8.6 of the EuroLinux operating system. It is compatible with the latest upstream release. With this release we focused on the support for modern software security technologies such as OpenSSL 3.0, verification of the versions of installed SELinux policies and updated hashing algorithms. New PHP and Perl versions have been added. The system was also enhanced by a secure version of log4j. Popular C/C++, Go and Rust compiler collections have been updated. The real-time Linux kernel test suite - rteval - has received the ability to specify a threshold value in microseconds. Options' names in Samba binaries have been standardized to provide a more consistent user interface. The changes will also satisfy the people who work with deep learning and deep neural networks - the OpenCV package in EuroLinux 8.6 now ships the dnn and text modules.
