Nagios Core 4.0.8 Available

Nagios Core 4.0.8 has just been released and can be downloaded from 
http://nagios.org/download

This version of Nagios Core incorporates many improvements, notably:
* JSON API output is better aligned with the standard, and output size 
limits have been lifted.
* Check scheduling has been modified to prevent bunching checks at the 
start of their timeperiod.
* Auto-rescheduling of checks has been reimplemented. This can be 
enabled by setting auto_reschedule_checks=1 in nagios.cfg, and adjusted 
by setting auto_rescheduling_interval and auto_rescheduling_window as 
described in the Core 4 Documentation: 
http://nagios.sourceforge.net/docs/nagioscore/4/en/configmain.html#auto_reschedule_checks. 
Auto-rescheduling smoothes the check schedule as it changes over time, 
and together with the previous improvements, helps to give a more 
uniform system load.
* Core workers handle variable assignments at the start of simple 
commands that otherwise don't require a subshell, eliminating the need 
for most uses of env.


Thanks to all who reported bugs, contributed patches, and helped test
