strace 5.9 released

[Dmitry V. Levin]

Starting with version 4.13, strace follows the schedule of linux kernel
and new versions of strace are released along with new versions of linux
kernel, so strace 5.9 is tagged and uploaded.

This release includes PID namespace translation support, implemented
by Ákos Uzonyi as his GSoC 2020 project.

I'd like to use this opportunity to welcome Elvira Khabirova back
as a contributor after two years of inactivity.

$ git tag -v v5.9 2> /dev/null | sed -n '/^$/,$p'
