October brought 122 new and updated software roundups to LinuxLinks. Each one helps readers find useful free and open source software, from familiar everyday applications to specialist tools that deserve a wider audience.

Keeping those guides accurate takes ongoing work. Projects gain features, change direction, or disappear; a timely reader tip can make a big difference.
