The second maintenance release of the NAV 4.0 series is now available, version 4.0.2.
The source code is available for download at Launchpad  and a new package for Debian Wheezy has been published in our APT repository .
The following reported bugs have been fixed:
* LP#1302403 (Unplugged HP power supplies are marked with "unknown" state) * LP#1303804 (No graphs are rendered if graphite base url doesn't end with a slash) * LP#1304279 (values in threshold alerts are always 100) * LP#1304455 (Submitting an empty search form crashes Arnold) * LP#1314503 (migrate_to_whisper.py crashes on mismatches between RRD files and database) * LP#1316091 (pping dies when carbon is unavailable) * LP#1316600 (external tools have no icons) * LP#1316965 (NAV 4.0 collects port traffic stats from EDGE devices)
Because the 3.15 and 4.0 series are maintained in parallel, you may need to use the -o option if you are executing the `navsyncdb` program manually for schema upgrades.
Happy NAVing everyone!
