[Modeling-users] Notification Framework v0.5 released

[Sebastien B. <sbi...@us...>]

        Hi all,

  The NotificationFramework is a python implementation of the "Observer"
Design Pattern, allowing one-to-many dependency between objects even when
they have no idea of who and where the other objects live.

This release fixes two important bugs implying:

  - addObserver() not reporting when an object tries to register two or
    more different callbacks,
=20=20
  - postNotification() copying the observers back to its own list,
    making it grow and causing degradation of performance each time it
    is called.

It also offers an implementation for RFE#742511 allowing multiple
callbacks per observer.

  The modeling framework itself is not affected by these changes and did
  not even triggered the bugs. However and since it may take advantages
  of these changes in the future, you'll probably want to upgrade your
  local copy.
