Known problems

The recommended SNMP library for use with ipdevpoll is `pynetsnmp`. If you
choose to go with the original TwistedSNMP, the latest version (0.3.13)
contains a bug that manifests in table retrieval operations. Timeouts and
retries aren't handled properly, and this may cause slow or otherwise busy
devices to be bombarded with requests from NAV. The `contrib/patches`
directory contains a patch for TwistedSNMP that solves this problem. The
patch has been submitted upstream, but not yet accepted into a new release.

Dependency changes

There are none :-)

Cabling and patches

The cabling and patch registry was introduced originally with NAV 3.0, but
never gained widespread usage, and had therefore fallen behind the rest of

The University of Linköping has graciously sponsored a reworking of the SeedDB
cabling and patch forms, so that these are now actually usable in a NAV
installation with more than a handful of switches, cables and patches.
Information about patch points is now also displayed on each port's ipdevinfo


NAV 4.5 adds a simple program, `navstats`, that can be used to periodically
extract stats from the NAV database and store those stats as Graphite metrics.
To configure your own stats, however, you need to know your way around SQL and
the NAV DB schema.

For more information, see the `navstats` reference documentation.

API changes

API tokens can now be managed more flexibly via the User Admin tool. Multiple
tokens can be issued and revoked separately. Each token has its own expiry
time and list of authorized API endpoints.
