Nagwin 2.0.0 is the first Nagwin package containing Nagios Core 4 binaries (4.0.2). As in earlier releases, we had to patch Nagios Core to handle external commands via a plain file based scheme, rather than pipes. In addition, all Nagwin services are now started by a new developed nagwin_service tool, solving some other challenges with the new process structure in Core 4. Nagwin 2.0.0 delivers Pnp4Nagios in bulk mode rather than the standard synchronous one, bringing performance gains for performance collection.

Existing customers can download the latest version from their customer pages at www.itefix.net, and can upgrade their existing installation by simply running the installer even if it is a major upgrade. All services will be registered again. Configuration files etc/nagios/nagios.cfg and etc/nagios/nagwin/commands.cfg will be overwritten for proper operation. However, your old files will still be available with the extension .pre-200.
