We have just released rsyslog 4.7.2, a member of the v4-devel branch. 4.7.2 is a bugfixing-release. Its primary bugfix solves problems with atomic instruction emulation. Users who have compiled rsyslog for older CPUs (like Intel 386) or CPUs for which gcc lacks atomic instruction support (like Sparc) are strongly encouraged to upgrade to the new versions. For all others, an update is optional. See Changelog for more details.
As always, feedback is appreciated.
