 Release notes for NAV 3.5
===========================
Please report bugs at https://bugs.launchpad.net/nav

If you are upgrading from versions of NAV older than 3.4, please refer
to the release notes of the in-between versions before reading any
further.


Netmap vs. Traffic Map
======================

The Traffic Map has been superseded by the Netmap.  Netmap does not
require a Java servlet backend, and in combination with a rewrite of
Network Explorer this means Tomcat is no longer needed for a NAV
installation.

If, for any reason, you really miss the old Traffic Map, you can find
it as a contrib under contrib/trafficmap/.  Refer to
contrib/trafficmap/README for installation instructions.


Upgrading from NAV 3.4
======================

Database changes
----------------
Whereas NAV 3.4 used four separate PostgreSQL databases (manage,
navprofiles, logger and arnold) to store its data, NAV 3.5 uses a
single database.

Before running the normal SQL upgrade procedure (i.e. SQL scripts from
doc/sql/upgrades/), you MUST merge your four existing NAV databases
into a single nav database.  The shell script doc/sql/mergedb.sh can
help you with this.  Se doc/sql/upgrades/README for more information.


Dependency changes
------------------
The following dependencies are new to NAV 3.5:

* python-django >= 1.0 (http://www.djangoproject.com)
* psycopg2 (in addition to psycopg1,
  http://www.initd.org/pub/software/psycopg/)

The following are no longer dependencies in NAV 3.5:

* Tomcat
* PHP
* The Perl modules DBD::Pg and SNMP_Session
* The Python module forgetHTML


Files to remove
---------------
These files and directories should be removed from your installation
after the upgrade:

apache/tools/editdb.tool
apache/tools/vlanPlot.tool
apache/tools/navAdmin.tool
apache/webroot/editdb/
apache/webroot/js/editdbTemplate.js
apache/webroot/style/editdbTemplate.css
apache/webroot/images/toolbox/tools/editdb.png
lib/python/nav/web/templates/editdbTemplate.py

You should rename etc/editdb.conf to etc/seeddb.conf if you have any
local changes to editdb.conf.

These files and directories are all prefixed with /usr/local/nav/ in a
default configuration, but your mileage may vary.
