Release 6.3 - 2025-06-18

New features

• The hw_info plugin now reports memory info units in human readable scale.

Bugfixes

• The /bin/dnf command is no longer hardcoded in the –calculate-build-dependencies code, and we use the standard config_opts['dnf5_command'] (or config_opts['dnf_command'], respectively).

• The mechanism for creating the mock group has been fixed again on Fedora/RHEL, because the built-in RPM user creation mechanism only works on F42 and newer. Mock on older distributions returned back to using %pre scriptlet.

• The mock-core-configs package files were previously owned by the mock group, same as a few files in mock package — which was unnecessary. These files are intended to be read-only and accessible by anyone. This issue was actually causing install-order problems when mock-core-configs or mock was installed before mock-filesystem. So newly those files have the default 0644, root, root ownership.

• This release includes a fix for a Python 3.14 incompatibility.

  Mock refused to start as non-root user with Python 3.14. This was because of the change in behaviour of ProcessPoolExecutor in Python. The code has been altered to work with both old and new Python.
