Migration
=========
Before performing any operation on NOC upgrade be sure:

* You have mercurial 1.3 or later
* python's system path contain no *protobuf* or *south*

With 0.5 release new application permission system introduced, leaving old
Django permissions obsolete. You need to reassing user permissions after upgrade.

General
=======

New Application Framework
-------------------------
0.5 release is a major step towards open telecom application platform. New
django-based application framework supports common development patterns
while containing a lot of telecom-related features. Web interface was completely
rewritten as a set of applications.

Four basic application classes are introduced:

* Applications - common application
* ModelApplication - wrapper for django's ModelAdmin, integrating django-based code in new framework
* Reports - common reporting engine
* SAApplication - Service Activation application wrapping map/reduce tasks

Each application define own set of permissions for granular access. Unittests included with every application,
helping to maintain code quality
