I have released syslog-ng 2.0.1, available at the usual places . I have added various missing bits that fell out in the 1.6.x -> 2.0.x change. These include: DNS cache support, overwrite_if_older (used to be called remove_if_older), various fixes, All-in-all 2.0.0 was a successful release, hopefully this one will not be much worse. See the NEWS entry of 2.0.1 for more information.
This blog describes my Home Automation related projects featuring KNX, a Buderus (Bosch) Boiler, custom built electronics, etc.
