One last shot this time for upcoming Icinga 1.0.1 and IDOUtils:
After getting several core patches into the master and also fixing duplicated service/hoststatus updates being sent to the neb module (thanks to Matthieu Kermagoret) there will be more improvements for IDOUtils.
Since the threaded housekeeper is doing fine, it is possible to periodically clean more tables. By popular demand, the following options have been added to ido2db.cfg

They can be used for your likings, by default they are not set.
If you want to help us test for the upcoming release, you are very welcome to do so!
To help you with GIT, we now have a quite detailed tutorial how to use GIT based on Icinga in our Developer Wiki =)
