Thanks Spunz. Nagios 2.0rc1 is now available for download
Depending on how well this release candidate goes, 2.0 may be released as stable in the next two or three weeks.nagios 2.0rc1
Changes since 2.0b6 include minor bug fixes and changes to the event broker API. If you are developing event broker modules, you'll need to grab a copy of the latest Nagios include files and recompile your modules. I was not expecting to change the event broker API before 2.0 was released as stable, but it seemed necessary, as a number of vital features were missing.
