best is to follow the git Changelog which we keep uptodate, when final 
changes are merged to 'next' from the different dev and test stages.

https://git.icinga.org/?p=icinga-core.git;a=blob;f=Changelog;hb=refs/heads/next

feature freeze is ~1 week from now, 3 weeks in advance of release, 2 
weeks before beta.

those rescheduled events did not discard the old event (and it's 
runtime) when adding a new event to host/service checks. so most likely 
your checks did get fired to often, causing a. more cpu time for that b. 
more logs c. more perfdata

in general, that would be not that much, but on larger systems, the 
number was even more severe, so that nailed down fix will suffice for 
everyone out there, regardless of the final numbers ;-)

kind regards,
