Hi all,

Today we are releasing the first bug-fix release of LTTng-Tools 2.6
release cycle. This release contains 120 changes, some of which
address stability issues of the relay daemon which were reported over
the last few weeks.

Considering the large number of fixes, we strongly encourage users to
update to 2.6.1.
