2009-12-20: Version 0.3.9-beta
---------------------------------
* Module 'utils.py' improved to have two main new functions: memoize and run_under_process
  - 'memoize' is a decorator that stores function results in memory and use it when the
    function is called again with the same arguments
  - 'run_under_process' is a decorator that run a function under a multiprocessing.Process
    instance, that means you use better the power of multi-core servers to generate reports

* To make the things easier to use decorator 'run_under_process', we created a new method
  on geraldo.base.Report class: 'generate_under_process_by', that stores the generation
  output in a temp file, using a process, and loads that file in the file-like object.

  is important to work with inheritance, and it is important to make a future
  important thing: events (specially BeforePrint and AfterPrint events)
* Fixed test of MatPlotLib support

2009-01-23: Version 0.2-alpha(4)
--------------------------------
* Removed all Django dependecy. Now when use '%(now:)s' macro in SystemField

  elements. This is important to make graphic elements in a detail band.

* graphics.Image with a new attribute 'get_image' to set manually functions
  to return image instead of load from PIL object or image. This is important
  to show images and charts depending on object values and logic.
